11:14
So uh today I'm going to cover uh you
11:14
So uh today I'm going to cover uh you know the blazer part uh basically so the
11:18
know the blazer part uh basically so the
11:18
know the blazer part uh basically so the topic name is unleashing the power of
11:20
topic name is unleashing the power of
11:20
topic name is unleashing the power of blazer the future of uh web development
11:22
blazer the future of uh web development
11:22
blazer the future of uh web development that's what I feel so as I mentioned
11:25
that's what I feel so as I mentioned
11:25
that's what I feel so as I mentioned earlier this is Chandu Shaker uh so
11:28
earlier this is Chandu Shaker uh so
11:28
earlier this is Chandu Shaker uh so currently working as an senior engineer
11:31
currently working as an senior engineer
11:31
currently working as an senior engineer for one of the uh biggest retail company
11:34
for one of the uh biggest retail company
11:34
for one of the uh biggest retail company uh so you know so you know uh I'll start
11:38
uh so you know so you know uh I'll start
11:38
uh so you know so you know uh I'll start with the introduction of to Blazer
11:40
with the introduction of to Blazer
11:40
with the introduction of to Blazer basically. So Blazer is a net print
11:43
basically. So Blazer is a net print
11:43
basically. So Blazer is a net print framework that allows you to build
11:46
framework that allows you to build
11:46
framework that allows you to build applications using C# and Razer
11:48
applications using C# and Razer
11:48
applications using C# and Razer components. So you know uh if you are
11:51
components. So you know uh if you are
11:51
components. So you know uh if you are familiar with the web development uh we
11:53
familiar with the web development uh we
11:54
familiar with the web development uh we are hearing lot of technologies like you
11:55
are hearing lot of technologies like you
11:55
are hearing lot of technologies like you know Angular, React, Vue.js JS and you
11:59
know Angular, React, Vue.js JS and you
11:59
know Angular, React, Vue.js JS and you know different different technologies
12:00
know different different technologies
12:00
know different different technologies but with
12:02
but with
12:02
but with bler we can develop the web application
12:04
bler we can develop the web application
12:04
bler we can develop the web application only with C# and uh with the Razer
12:08
only with C# and uh with the Razer
12:08
only with C# and uh with the Razer components and also we have the
12:10
components and also we have the
12:10
components and also we have the privilege or you know we have uh the
12:12
privilege or you know we have uh the
12:12
privilege or you know we have uh the capability within the blazer that we can
12:15
capability within the blazer that we can
12:15
capability within the blazer that we can interact with the JavaScript as well. So
12:18
interact with the JavaScript as well. So
12:18
interact with the JavaScript as well. So you know it's a powerful tool that
12:20
you know it's a powerful tool that
12:20
you know it's a powerful tool that enables you to create fast interactive
12:22
enables you to create fast interactive
12:22
enables you to create fast interactive and scalable web applications. So you
12:25
and scalable web applications. So you
12:25
and scalable web applications. So you know unlike other JavaScript based
12:27
know unlike other JavaScript based
12:27
know unlike other JavaScript based frameworks, Blazer allows you to write
12:31
frameworks, Blazer allows you to write
12:31
frameworks, Blazer allows you to write rich web applications entirely in C#
12:35
rich web applications entirely in C#
12:35
rich web applications entirely in C# eliminating the need to switch between
12:36
eliminating the need to switch between
12:36
eliminating the need to switch between the languages for backend and print
12:39
the languages for backend and print
12:39
the languages for backend and print development. So we can develop the
12:42
development. So we can develop the
12:42
development. So we can develop the scalable applications the web
12:44
scalable applications the web
12:44
scalable applications the web applications basically entirely in C#.
12:47
applications basically entirely in C#.
12:48
applications basically entirely in C#. It combines the uh power of net with uh
12:51
It combines the uh power of net with uh
12:51
It combines the uh power of net with uh simplicity of modern web development
12:53
simplicity of modern web development
12:53
simplicity of modern web development without relying on the JavaScript. So
12:55
without relying on the JavaScript. So
12:55
without relying on the JavaScript. So that is the biggest advantage of
12:57
that is the biggest advantage of
12:57
that is the biggest advantage of blazer and also uh it simplifies the
13:00
blazer and also uh it simplifies the
13:00
blazer and also uh it simplifies the fullstack development for net developers
13:02
fullstack development for net developers
13:02
fullstack development for net developers by allowing code sharing between the
13:05
by allowing code sharing between the
13:05
by allowing code sharing between the client and server. So it was introduced
13:07
client and server. So it was introduced
13:07
client and server. So it was introduced in 2017 by Steve Sanderson at uh Oslo.
13:11
in 2017 by Steve Sanderson at uh Oslo.
13:11
in 2017 by Steve Sanderson at uh Oslo. It leverages basically you know the web
13:13
It leverages basically you know the web
13:13
It leverages basically you know the web assembly for client side execution. So
13:15
assembly for client side execution. So
13:15
assembly for client side execution. So the blazer the name you know the history
13:18
the blazer the name you know the history
13:18
the blazer the name you know the history behind it is a mix of browser and razor.
13:21
behind it is a mix of browser and razor.
13:21
behind it is a mix of browser and razor. So you know reflecting its ability to
13:23
So you know reflecting its ability to
13:23
So you know reflecting its ability to run C# code in the browser replacing the
13:27
run C# code in the browser replacing the
13:27
run C# code in the browser replacing the traditional server side rendering within
13:29
traditional server side rendering within
13:29
traditional server side rendering within uh client side approach. So this is all
13:32
uh client side approach. So this is all
13:32
uh client side approach. So this is all about the introduction to blazer. So you
13:34
about the introduction to blazer. So you
13:34
about the introduction to blazer. So you know I would like to give an dive into
13:36
know I would like to give an dive into
13:36
know I would like to give an dive into the blazer. Uh so you know I would like
13:39
the blazer. Uh so you know I would like
13:39
the blazer. Uh so you know I would like to start with the key features of
13:41
to start with the key features of
13:41
to start with the key features of blazer. So Blazer supports or you know
13:45
blazer. So Blazer supports or you know
13:45
blazer. So Blazer supports or you know blazer is an component based
13:47
blazer is an component based
13:47
blazer is an component based architecture. So build we can build the
13:50
architecture. So build we can build the
13:50
architecture. So build we can build the reusable UI components with C#, HTML and
13:54
reusable UI components with C#, HTML and
13:54
reusable UI components with C#, HTML and CSS like we do in Angular or React. You
13:57
CSS like we do in Angular or React. You
13:57
CSS like we do in Angular or React. You know we'll have the same sort of thing
13:59
know we'll have the same sort of thing
13:59
know we'll have the same sort of thing like you know we can build our
14:01
like you know we can build our
14:01
like you know we can build our components. It supports you know two
14:04
components. It supports you know two
14:04
components. It supports you know two hosting models. I said two but I
14:06
hosting models. I said two but I
14:06
hosting models. I said two but I mentioned three. I'll give you the
14:08
mentioned three. I'll give you the
14:08
mentioned three. I'll give you the history as well. you know till net 6 or
14:11
history as well. you know till net 6 or
14:11
history as well. you know till net 6 or 7 uh we have a web blazer server and the
14:14
7 uh we have a web blazer server and the
14:14
7 uh we have a web blazer server and the blazer web assembly but in net 8 onwards
14:18
blazer web assembly but in net 8 onwards
14:18
blazer web assembly but in net 8 onwards you know we are having the blazer web
14:19
you know we are having the blazer web
14:19
you know we are having the blazer web assembly and blazer hybrid so the blazer
14:22
assembly and blazer hybrid so the blazer
14:22
assembly and blazer hybrid so the blazer server is basically you know it supports
14:25
server is basically you know it supports
14:25
server is basically you know it supports server side rendering with realtime
14:27
server side rendering with realtime
14:27
server side rendering with realtime updates via signal whereas uh the blazer
14:31
updates via signal whereas uh the blazer
14:31
updates via signal whereas uh the blazer web assembly is in you know the client
14:33
web assembly is in you know the client
14:33
web assembly is in you know the client side rendering so you know uh typically
14:36
side rendering so you know uh typically
14:36
side rendering so you know uh typically it works as in web assembly rendering
14:38
it works as in web assembly rendering
14:38
it works as in web assembly rendering like you the code whatever is compiled
14:40
like you the code whatever is compiled
14:40
like you the code whatever is compiled will be downloaded to the browser side
14:43
will be downloaded to the browser side
14:43
will be downloaded to the browser side and from there you know it will operates
14:46
and from there you know it will operates
14:46
and from there you know it will operates whereas blazer hybrid from net 8 onwards
14:49
whereas blazer hybrid from net 8 onwards
14:49
whereas blazer hybrid from net 8 onwards you know it will have uh you know it
14:52
you know it will have uh you know it
14:52
you know it will have uh you know it targets basically uh the web desktop you
14:55
targets basically uh the web desktop you
14:55
targets basically uh the web desktop you know the maui basically you know I'm
14:56
know the maui basically you know I'm
14:56
know the maui basically you know I'm talking about so as as as I mentioned
14:59
talking about so as as as I mentioned
14:59
talking about so as as as I mentioned you know the blazer supports the uh web
15:02
you know the blazer supports the uh web
15:02
you know the blazer supports the uh web development as well as the desktop
15:04
development as well as the desktop
15:04
development as well as the desktop development and mobile development
15:08
development and mobile development
15:08
development and mobile development And also it supports you know the
15:10
And also it supports you know the
15:10
And also it supports you know the JavaScript interoperability meaning that
15:12
JavaScript interoperability meaning that
15:12
JavaScript interoperability meaning that you know it integrates with the existing
15:14
you know it integrates with the existing
15:14
you know it integrates with the existing JavaScript libraries as well as from
15:17
JavaScript libraries as well as from
15:17
JavaScript libraries as well as from JavaScript we can able to call the C#
15:21
JavaScript we can able to call the C#
15:21
JavaScript we can able to call the C# code as well. So you know when we are
15:24
code as well. So you know when we are
15:24
code as well. So you know when we are looking back into the history like you
15:26
looking back into the history like you
15:26
looking back into the history like you know when we have ASP.NET
15:28
know when we have ASP.NET
15:28
know when we have ASP.NET uh ASP.NET MVC you know whatever you
15:31
uh ASP.NET MVC you know whatever you
15:31
uh ASP.NET MVC you know whatever you know we develop you know somehow we rely
15:34
know we develop you know somehow we rely
15:34
know we develop you know somehow we rely on the JavaScript here also you know it
15:36
on the JavaScript here also you know it
15:36
on the JavaScript here also you know it supports the same sort of thing but uh
15:39
supports the same sort of thing but uh
15:39
supports the same sort of thing but uh it's more into razor and you know more
15:41
it's more into razor and you know more
15:41
it's more into razor and you know more into the C# kind of thing. So these are
15:44
into the C# kind of thing. So these are
15:44
into the C# kind of thing. So these are the key features of
15:46
the key features of
15:46
the key features of blazer. Uh so you know I would like to
15:50
blazer. Uh so you know I would like to
15:50
blazer. Uh so you know I would like to elaborate more on the component based
15:54
elaborate more on the component based
15:54
elaborate more on the component based architecture. So
15:56
architecture. So
15:56
architecture. So uh blazer apps are based on the
16:00
uh blazer apps are based on the
16:00
uh blazer apps are based on the components. So a component in blazer is
16:03
components. So a component in blazer is
16:03
components. So a component in blazer is an element of UI. Say for example you
16:05
an element of UI. Say for example you
16:05
an element of UI. Say for example you know we can the button is a
16:09
know we can the button is a
16:09
know we can the button is a component. So you know uh any element of
16:14
component. So you know uh any element of
16:14
component. So you know uh any element of UI is an component such as a page or a
16:16
UI is an component such as a page or a
16:16
UI is an component such as a page or a dialogue or in data entry form you know
16:20
dialogue or in data entry form you know
16:20
dialogue or in data entry form you know whatever you know we'll call it as an
16:22
whatever you know we'll call it as an
16:22
whatever you know we'll call it as an component components are net car classes
16:25
component components are net car classes
16:25
component components are net car classes built into net assemblies basically so
16:28
built into net assemblies basically so
16:28
built into net assemblies basically so it defines the flexible UI rendering
16:30
it defines the flexible UI rendering
16:30
it defines the flexible UI rendering logic handle user events can be nested
16:34
logic handle user events can be nested
16:34
logic handle user events can be nested and reused so the main purpose is you
16:37
and reused so the main purpose is you
16:37
and reused so the main purpose is you know reusability so it increases the
16:40
know reusability so it increases the
16:40
know reusability so it increases the reusable if we create the components in
16:42
reusable if we create the components in
16:42
reusable if we create the components in an appropriate
16:44
an appropriate
16:44
an appropriate way and also the components the
16:46
way and also the components the
16:46
way and also the components the component class is as usually written in
16:49
component class is as usually written in
16:49
component class is as usually written in the form of razor markup language with
16:52
the form of razor markup language with
16:52
the form of razor markup language with dotrazer file extension. Razer is a
16:55
dotrazer file extension. Razer is a
16:55
dotrazer file extension. Razer is a syntax for combining HTML markup with C#
16:58
syntax for combining HTML markup with C#
16:58
syntax for combining HTML markup with C# code and designed for developer
17:00
code and designed for developer
17:00
code and designed for developer productivity. So see here you know on
17:02
productivity. So see here you know on
17:02
productivity. So see here you know on the right hand side I mentioned you know
17:04
the right hand side I mentioned you know
17:04
the right hand side I mentioned you know um the code basically you know at the
17:06
um the code basically you know at the
17:06
um the code basically you know at the rate code and then we are writing the
17:09
rate code and then we are writing the
17:09
rate code and then we are writing the methods that can be invoked. See here
17:11
methods that can be invoked. See here
17:11
methods that can be invoked. See here the increment count is a method that is
17:15
the increment count is a method that is
17:15
the increment count is a method that is being used at on click. So you know this
17:18
being used at on click. So you know this
17:18
being used at on click. So you know this method is being called here. So the
17:21
method is being called here. So the
17:21
method is being called here. So the components render into an inmemory
17:23
components render into an inmemory
17:24
components render into an inmemory representation of the browser's
17:25
representation of the browser's
17:25
representation of the browser's documentation that is DOM basically you
17:27
documentation that is DOM basically you
17:27
documentation that is DOM basically you know called render a tree which is used
17:30
know called render a tree which is used
17:30
know called render a tree which is used to update the UI in flexible and
17:33
to update the UI in flexible and
17:33
to update the UI in flexible and efficient way. Okay. So this is all
17:35
efficient way. Okay. So this is all
17:35
efficient way. Okay. So this is all about the component based architecture.
17:37
about the component based architecture.
17:37
about the component based architecture. So you know now I would like to you know
17:39
So you know now I would like to you know
17:39
So you know now I would like to you know go into the hosting
17:41
go into the hosting
17:41
go into the hosting models.
17:45
So as I mentioned uh you know one of the
17:48
So as I mentioned uh you know one of the
17:48
So as I mentioned uh you know one of the hosting model is blazer server. So it
17:51
hosting model is blazer server. So it
17:51
hosting model is blazer server. So it supports hosting of the Razer components
17:54
supports hosting of the Razer components
17:54
supports hosting of the Razer components on the server in an ASP.NET core
17:57
on the server in an ASP.NET core
17:57
on the server in an ASP.NET core environment. So you know assume that you
17:59
environment. So you know assume that you
17:59
environment. So you know assume that you know uh this is the server and uh we
18:01
know uh this is the server and uh we
18:02
know uh this is the server and uh we have the
18:03
have the
18:03
have the ASP.NET core here and you know resides
18:06
ASP.NET core here and you know resides
18:06
ASP.NET core here and you know resides that you know we'll have the tazer
18:08
that you know we'll have the tazer
18:08
that you know we'll have the tazer components. So these razor components
18:11
components. So these razor components
18:11
components. So these razor components basically you know will be rendered as
18:14
basically you know will be rendered as
18:14
basically you know will be rendered as in DOM but you know the interactivity
18:17
in DOM but you know the interactivity
18:17
in DOM but you know the interactivity will be happen through
18:19
will be happen through
18:19
will be happen through signaler. So uh here I I'll go uh into
18:22
signaler. So uh here I I'll go uh into
18:22
signaler. So uh here I I'll go uh into deep. So you know the UI updates and
18:26
deep. So you know the UI updates and
18:26
deep. So you know the UI updates and event handling and the JS calls are
18:28
event handling and the JS calls are
18:28
event handling and the JS calls are handled over signal connection using the
18:31
handled over signal connection using the
18:31
handled over signal connection using the websocket protocol. So in a way it's a
18:35
websocket protocol. So in a way it's a
18:35
websocket protocol. So in a way it's a blessing uh because you know the end
18:38
blessing uh because you know the end
18:38
blessing uh because you know the end user doesn't know that uh something is
18:41
user doesn't know that uh something is
18:41
user doesn't know that uh something is happening. So it will give an single
18:43
happening. So it will give an single
18:44
happening. So it will give an single page application
18:46
page application
18:46
page application uh kind of field to the end user but
18:49
uh kind of field to the end user but
18:49
uh kind of field to the end user but internally it uses signaler and it will
18:52
internally it uses signaler and it will
18:52
internally it uses signaler and it will communicate through websockets protocol.
18:55
communicate through websockets protocol.
18:55
communicate through websockets protocol. the runtime stays on the server side um
18:58
the runtime stays on the server side um
18:58
the runtime stays on the server side um and uh executes the you know the
18:59
and uh executes the you know the
19:00
and uh executes the you know the application C#ar code and sending the UI
19:02
application C#ar code and sending the UI
19:02
application C#ar code and sending the UI events from the browser to the server
19:04
events from the browser to the server
19:04
events from the browser to the server and also you know applying the applying
19:06
and also you know applying the applying
19:06
and also you know applying the applying back the UI updates to render the
19:09
back the UI updates to render the
19:09
back the UI updates to render the component that are sent back by the
19:11
component that are sent back by the
19:11
component that are sent back by the server. So the changes will be applied
19:13
server. So the changes will be applied
19:13
server. So the changes will be applied on the DOM side but you know the
19:16
on the DOM side but you know the
19:16
on the DOM side but you know the communication will be happened through
19:18
communication will be happened through
19:18
communication will be happened through signal arc in blazer server hosting
19:20
signal arc in blazer server hosting
19:20
signal arc in blazer server hosting model. So when a razor page or a view is
19:23
model. So when a razor page or a view is
19:23
model. So when a razor page or a view is rendered to the browser, every line of
19:26
rendered to the browser, every line of
19:26
rendered to the browser, every line of Razer code emits the HTML in text format
19:31
Razer code emits the HTML in text format
19:31
Razer code emits the HTML in text format so that you know it will be rendered the
19:33
so that you know it will be rendered the
19:33
so that you know it will be rendered the HTML will be rendered on the DOM side or
19:36
HTML will be rendered on the DOM side or
19:36
HTML will be rendered on the DOM side or the browser side. The blazer produces a
19:39
the browser side. The blazer produces a
19:39
the browser side. The blazer produces a graph of the components. So you know uh
19:41
graph of the components. So you know uh
19:41
graph of the components. So you know uh all the components that are rendered as
19:44
all the components that are rendered as
19:44
all the components that are rendered as in
19:45
in
19:45
in HTML will be rendered as a graph of the
19:48
HTML will be rendered as a graph of the
19:48
HTML will be rendered as a graph of the components to display on uh you know to
19:52
components to display on uh you know to
19:52
components to display on uh you know to display basically similar to HTML or you
19:54
display basically similar to HTML or you
19:54
display basically similar to HTML or you know the XML dom a component is disposed
19:58
know the XML dom a component is disposed
19:58
know the XML dom a component is disposed after the user navigates to another
20:00
after the user navigates to another
20:00
after the user navigates to another place. So to you know get the memory
20:02
place. So to you know get the memory
20:02
place. So to you know get the memory optimization. So whenever we are
20:04
optimization. So whenever we are
20:04
optimization. So whenever we are navigating from one component to another
20:06
navigating from one component to another
20:06
navigating from one component to another component the it will dispose that
20:09
component the it will dispose that
20:09
component the it will dispose that particular component which is being uh
20:12
particular component which is being uh
20:12
particular component which is being uh you know
20:13
you know
20:13
you know rendered. So after the UA components are
20:16
rendered. So after the UA components are
20:16
rendered. So after the UA components are interactive on the UI and you know the
20:18
interactive on the UI and you know the
20:18
interactive on the UI and you know the UI updates are triggered by the user
20:20
UI updates are triggered by the user
20:20
UI updates are triggered by the user interactions and the app events when an
20:24
interactions and the app events when an
20:24
interactions and the app events when an update occurs the component graph is
20:26
update occurs the component graph is
20:26
update occurs the component graph is rendered. you know I I already mentioned
20:28
rendered. you know I I already mentioned
20:28
rendered. you know I I already mentioned and also you know the signaler basically
20:30
and also you know the signaler basically
20:30
and also you know the signaler basically you know everybody knows about the
20:32
you know everybody knows about the
20:32
you know everybody knows about the signaler but you know to be
20:36
signaler but you know to be
20:36
signaler but you know to be uh to be on the point here you know on
20:39
uh to be on the point here you know on
20:39
uh to be on the point here you know on this context signal is an powerful
20:41
this context signal is an powerful
20:41
this context signal is an powerful library uh developed by Microsoft that
20:45
library uh developed by Microsoft that
20:45
library uh developed by Microsoft that uh know seamlessly incorporate realtime
20:47
uh know seamlessly incorporate realtime
20:47
uh know seamlessly incorporate realtime functionality into applications so it
20:51
functionality into applications so it
20:51
functionality into applications so it allows you to push content from the
20:53
allows you to push content from the
20:53
allows you to push content from the server to connected clients in the real
20:55
server to connected clients in the real
20:56
server to connected clients in the real time so That's how the signal works. So
20:58
time so That's how the signal works. So
20:58
time so That's how the signal works. So now I'm know uh going to blazer web
21:04
now I'm know uh going to blazer web
21:04
now I'm know uh going to blazer web assembly. So the blazer web assembly is
21:08
assembly. So the blazer web assembly is
21:08
assembly. So the blazer web assembly is completely a different approach from the
21:11
completely a different approach from the
21:11
completely a different approach from the blazer. So you know blazer web assembly
21:14
blazer. So you know blazer web assembly
21:14
blazer. So you know blazer web assembly is an single page application framework
21:16
is an single page application framework
21:16
is an single page application framework for building the interactive client side
21:18
for building the interactive client side
21:18
for building the interactive client side web apps withn
21:20
web apps withn
21:20
web apps withn net and uh running net code inside the
21:26
net and uh running net code inside the
21:26
net and uh running net code inside the browser is made possible by web web
21:28
browser is made possible by web web
21:28
browser is made possible by web web assembly as I mentioned. So you know
21:31
assembly as I mentioned. So you know
21:31
assembly as I mentioned. So you know whenever a web assembly project is
21:34
whenever a web assembly project is
21:34
whenever a web assembly project is application is built and run you know
21:37
application is built and run you know
21:37
application is built and run you know four things will happen. The C# code
21:39
four things will happen. The C# code
21:39
four things will happen. The C# code files and rather files are compiled into
21:42
files and rather files are compiled into
21:42
files and rather files are compiled into net assemblies and those assemblies will
21:45
net assemblies and those assemblies will
21:45
net assemblies and those assemblies will be downloaded to the
21:47
be downloaded to the
21:47
be downloaded to the browser and blazer boot you know the
21:50
browser and blazer boot you know the
21:50
browser and blazer boot you know the blazer web assembly bootstrap the net
21:53
blazer web assembly bootstrap the net
21:53
blazer web assembly bootstrap the net web assembly runtime and configures the
21:56
web assembly runtime and configures the
21:56
web assembly runtime and configures the runtime to load the assemblies for the
21:58
runtime to load the assemblies for the
21:58
runtime to load the assemblies for the application. So you know everything will
21:59
application. So you know everything will
21:59
application. So you know everything will be bootstrapped and you know downloaded
22:00
be bootstrapped and you know downloaded
22:00
be bootstrapped and you know downloaded to the browser. The runtime uses. So
22:04
to the browser. The runtime uses. So
22:04
to the browser. The runtime uses. So here it is not like blazer server app
22:08
here it is not like blazer server app
22:08
here it is not like blazer server app but here you know the way it works is
22:10
but here you know the way it works is
22:10
but here you know the way it works is the runtime uses the JavaScript interop
22:12
the runtime uses the JavaScript interop
22:12
the runtime uses the JavaScript interop to handle the DOM manipulations and
22:14
to handle the DOM manipulations and
22:14
to handle the DOM manipulations and browser API
22:16
browser API
22:16
browser API calls and blazer web assembly optimizes
22:19
calls and blazer web assembly optimizes
22:19
calls and blazer web assembly optimizes the payload size to reduce the download
22:21
the payload size to reduce the download
22:21
the payload size to reduce the download times. So if you are building an you
22:23
times. So if you are building an you
22:23
times. So if you are building an you know very big application the download
22:25
know very big application the download
22:25
know very big application the download time will be very you know will be huge.
22:28
time will be very you know will be huge.
22:28
time will be very you know will be huge. So you know to reduce that basically
22:30
So you know to reduce that basically
22:30
So you know to reduce that basically what they are doing is you know unused
22:32
what they are doing is you know unused
22:32
what they are doing is you know unused code is shipped out of the app when it
22:34
code is shipped out of the app when it
22:34
code is shipped out of the app when it is published by the IL trimmer and HTTP
22:38
is published by the IL trimmer and HTTP
22:38
is published by the IL trimmer and HTTP response are compressed the net runtime
22:41
response are compressed the net runtime
22:41
response are compressed the net runtime and assemblies are catched in the
22:42
and assemblies are catched in the
22:42
and assemblies are catched in the browser. So this is how you know uh on
22:45
browser. So this is how you know uh on
22:45
browser. So this is how you know uh on an high level it's all about the blazer
22:48
an high level it's all about the blazer
22:48
an high level it's all about the blazer web assembly. So I think I'm good. So
22:51
web assembly. So I think I'm good. So
22:51
web assembly. So I think I'm good. So any questions for me?
22:54
Uh okay
22:57
Uh okay
22:57
Uh okay fine. So now I'm going to
23:01
fine. So now I'm going to
23:01
fine. So now I'm going to uh
23:05
the blazer hybrid. So it is from net 8.
23:09
the blazer hybrid. So it is from net 8.
23:09
the blazer hybrid. So it is from net 8. Uh you know this functionality or you
23:11
Uh you know this functionality or you
23:11
Uh you know this functionality or you know this one is uh coming from the net
23:14
know this one is uh coming from the net
23:14
know this one is uh coming from the net 8. So Blazer hybrid enables using the
23:17
8. So Blazer hybrid enables using the
23:17
8. So Blazer hybrid enables using the Razer components in an native client tab
23:20
Razer components in an native client tab
23:20
Razer components in an native client tab with a blend of native and web
23:22
with a blend of native and web
23:22
with a blend of native and web technologies for the web mobile and
23:23
technologies for the web mobile and
23:23
technologies for the web mobile and desktop platform. So basically uh the
23:26
desktop platform. So basically uh the
23:26
desktop platform. So basically uh the code runs natively in the net process
23:28
code runs natively in the net process
23:28
code runs natively in the net process and renders the web UA to an embedded
23:31
and renders the web UA to an embedded
23:31
and renders the web UA to an embedded web view control. So web assembly isn't
23:35
web view control. So web assembly isn't
23:35
web view control. So web assembly isn't used in hybrid apps but it uses you know
23:38
used in hybrid apps but it uses you know
23:38
used in hybrid apps but it uses you know it the hybrid apps are built with net
23:41
it the hybrid apps are built with net
23:41
it the hybrid apps are built with net maui which is a crossplatform framework
23:44
maui which is a crossplatform framework
23:44
maui which is a crossplatform framework for creating native mobile and desktop
23:47
for creating native mobile and desktop
23:47
for creating native mobile and desktop apps with car and zaml. So blazer hybrid
23:51
apps with car and zaml. So blazer hybrid
23:51
apps with car and zaml. So blazer hybrid supports WPF and Windows forms to
23:54
supports WPF and Windows forms to
23:54
supports WPF and Windows forms to transition applications from earlier
23:57
transition applications from earlier
23:57
transition applications from earlier technology to net mode. So it
23:59
technology to net mode. So it
23:59
technology to net mode. So it particularly well suited for the
24:01
particularly well suited for the
24:01
particularly well suited for the building the applications that needed to
24:02
building the applications that needed to
24:02
building the applications that needed to run both desktop mobile platforms. So
24:05
run both desktop mobile platforms. So
24:05
run both desktop mobile platforms. So this is all about blazer app. So I'll
24:08
this is all about blazer app. So I'll
24:08
this is all about blazer app. So I'll talk about you know benefits,
24:11
talk about you know benefits,
24:11
talk about you know benefits, limitations and challenges but you know
24:13
limitations and challenges but you know
24:13
limitations and challenges but you know I'll come to this slide later point of
24:15
I'll come to this slide later point of
24:15
I'll come to this slide later point of time but I would like to cover the
24:17
time but I would like to cover the
24:17
time but I would like to cover the reasons to adopt
24:19
reasons to adopt
24:19
reasons to adopt Blazer. Okay. So uh the blazer offers
24:23
Blazer. Okay. So uh the blazer offers
24:23
Blazer. Okay. So uh the blazer offers unified development language. So Blazer
24:26
unified development language. So Blazer
24:26
unified development language. So Blazer allows you to use
24:27
allows you to use
24:27
allows you to use C# you know for both front end and
24:30
C# you know for both front end and
24:30
C# you know for both front end and backend development reducing the need to
24:33
backend development reducing the need to
24:33
backend development reducing the need to switch the switch between the languages.
24:35
switch the switch between the languages.
24:35
switch the switch between the languages. So Angular React primarily uses
24:38
So Angular React primarily uses
24:38
So Angular React primarily uses JavaScript TypeScript which might
24:39
JavaScript TypeScript which might
24:40
JavaScript TypeScript which might require additional learning for a net
24:42
require additional learning for a net
24:42
require additional learning for a net developer. But you know if you are
24:43
developer. But you know if you are
24:43
developer. But you know if you are developing the
24:44
developing the
24:44
developing the application using blazer you doesn't
24:47
application using blazer you doesn't
24:47
application using blazer you doesn't need to you can develop the web web
24:50
need to you can develop the web web
24:50
need to you can develop the web web application with the help of shar and
24:53
application with the help of shar and
24:53
application with the help of shar and also you know it it it offers seamless
24:55
also you know it it it offers seamless
24:55
also you know it it it offers seamless integration with net blazer integrates
24:59
integration with net blazer integrates
24:59
integration with net blazer integrates you know deeply with the net ecosystem
25:01
you know deeply with the net ecosystem
25:01
you know deeply with the net ecosystem making it easier to use existing
25:03
making it easier to use existing
25:03
making it easier to use existing libraries and tools. This can be
25:06
libraries and tools. This can be
25:06
libraries and tools. This can be streamlined development process for
25:08
streamlined development process for
25:08
streamlined development process for teams already using net technology. So
25:11
teams already using net technology. So
25:11
teams already using net technology. So you know it offers seamless integration
25:13
you know it offers seamless integration
25:13
you know it offers seamless integration with the net and also uh it offers
25:17
with the net and also uh it offers
25:17
with the net and also uh it offers component reusability. So blazer
25:19
component reusability. So blazer
25:19
component reusability. So blazer components can be reused across
25:21
components can be reused across
25:21
components can be reused across different different platforms including
25:23
different different platforms including
25:23
different different platforms including web mobile and desktop applications
25:26
web mobile and desktop applications
25:26
web mobile and desktop applications through net mi and also you know the
25:30
through net mi and also you know the
25:30
through net mi and also you know the angular and react when it comes to
25:31
angular and react when it comes to
25:31
angular and react when it comes to angular and react it al supports the
25:33
angular and react it al supports the
25:33
angular and react it al supports the component based architecture but may
25:35
component based architecture but may
25:35
component based architecture but may require different frameworks for mobile
25:37
require different frameworks for mobile
25:37
require different frameworks for mobile and desktop but in you know in if you're
25:41
and desktop but in you know in if you're
25:41
and desktop but in you know in if you're developing an
25:42
developing an
25:42
developing an application targeting
25:44
application targeting
25:44
application targeting crossplatforms with the help of net moi
25:47
crossplatforms with the help of net moi
25:47
crossplatforms with the help of net moi you know we
25:49
you know we
25:49
you know we develop the applications to support the
25:52
develop the applications to support the
25:52
develop the applications to support the cross
25:54
cross
25:54
cross platforms and uh when it comes to the
25:57
platforms and uh when it comes to the
25:57
platforms and uh when it comes to the performance improvements like you know
25:58
performance improvements like you know
25:58
performance improvements like you know the blazer web assembly has significant
26:01
the blazer web assembly has significant
26:01
the blazer web assembly has significant performance enhancements with net 8 I
26:04
performance enhancements with net 8 I
26:04
performance enhancements with net 8 I see uh as in you know I'm past 2 years
26:08
see uh as in you know I'm past 2 years
26:08
see uh as in you know I'm past 2 years or 3 years I'm working on blazer so with
26:10
or 3 years I'm working on blazer so with
26:10
or 3 years I'm working on blazer so with net 8 I'm seeing lot of enhancements
26:14
net 8 I'm seeing lot of enhancements
26:14
net 8 I'm seeing lot of enhancements uh so including the reduced app sizes
26:17
uh so including the reduced app sizes
26:17
uh so including the reduced app sizes and foster load times. Uh, Angular and
26:20
and foster load times. Uh, Angular and
26:20
and foster load times. Uh, Angular and React have their own performance
26:21
React have their own performance
26:21
React have their own performance optimizations but may not benefit from
26:24
optimizations but may not benefit from
26:24
optimizations but may not benefit from the same level of integration with net.
26:27
the same level of integration with net.
26:27
the same level of integration with net. So these are the you know four reasons I
26:31
So these are the you know four reasons I
26:31
So these are the you know four reasons I mentioned uh as uh you know the main
26:34
mentioned uh as uh you know the main
26:34
mentioned uh as uh you know the main reasons to adopt the blazer. So when to
26:38
reasons to adopt the blazer. So when to
26:38
reasons to adopt the blazer. So when to adopt the blazer? So you know we have
26:40
adopt the blazer? So you know we have
26:40
adopt the blazer? So you know we have angular, we have react and we have
26:42
angular, we have react and we have
26:42
angular, we have react and we have legacy application. So you know it is
26:45
legacy application. So you know it is
26:45
legacy application. So you know it is very important to know when to adopt the
26:48
very important to know when to adopt the
26:48
very important to know when to adopt the blazer. So if you are having an existing
26:51
blazer. So if you are having an existing
26:51
blazer. So if you are having an existing net
26:52
net
26:52
net infrastructure then you know it is
26:54
infrastructure then you know it is
26:54
infrastructure then you know it is better to adopt blazer to modernize your
26:58
better to adopt blazer to modernize your
26:58
better to adopt blazer to modernize your application. So if your organization has
27:00
application. So if your organization has
27:00
application. So if your organization has an uh you know uh already has a
27:02
an uh you know uh already has a
27:02
an uh you know uh already has a significant investment in net
27:04
significant investment in net
27:04
significant investment in net technologies adopting blazer can
27:06
technologies adopting blazer can
27:06
technologies adopting blazer can leverage existing skills and
27:08
leverage existing skills and
27:08
leverage existing skills and infrastructure. So and also the
27:11
infrastructure. So and also the
27:11
infrastructure. So and also the fullstack development as I mentioned uh
27:12
fullstack development as I mentioned uh
27:12
fullstack development as I mentioned uh you know through C#
27:16
you know through C#
27:16
you know through C# uh we can develop both front end as well
27:19
uh we can develop both front end as well
27:19
uh we can develop both front end as well as the backend code and also uh this is
27:24
as the backend code and also uh this is
27:24
as the backend code and also uh this is also I mentioned like you know the
27:25
also I mentioned like you know the
27:25
also I mentioned like you know the crossplatform application support with
27:27
crossplatform application support with
27:27
crossplatform application support with the net moi you know we can able
27:31
the net moi you know we can able
27:31
the net moi you know we can able to develop the crossplatform
27:34
to develop the crossplatform
27:34
to develop the crossplatform applications and also the realtime
27:36
applications and also the realtime
27:36
applications and also the realtime applications. So if you are looking into
27:38
applications. So if you are looking into
27:38
applications. So if you are looking into the blazer server uh you know it
27:41
the blazer server uh you know it
27:41
the blazer server uh you know it communicates from client to server using
27:44
communicates from client to server using
27:44
communicates from client to server using signal right so you know uh it is well
27:47
signal right so you know uh it is well
27:47
signal right so you know uh it is well suited for the realtime applications
27:49
suited for the realtime applications
27:49
suited for the realtime applications where server side rendering and the
27:51
where server side rendering and the
27:51
where server side rendering and the constant server connections are
27:54
constant server connections are
27:54
constant server connections are beneficial so and you know the long-term
27:58
beneficial so and you know the long-term
27:58
beneficial so and you know the long-term project so you know if you are going
27:59
project so you know if you are going
27:59
project so you know if you are going with angular or react or any other open
28:04
with angular or react or any other open
28:04
with angular or react or any other open sources like you know will the
28:06
sources like you know will the
28:06
sources like you know will the maintenance will be heavy because you
28:08
maintenance will be heavy because you
28:08
maintenance will be heavy because you know we may develop using few libraries
28:11
know we may develop using few libraries
28:11
know we may develop using few libraries those will be obsolated at one point of
28:14
those will be obsolated at one point of
28:14
those will be obsolated at one point of time and you
28:16
time and you
28:16
time and you know yeah so you know as it is uh net uh
28:22
know yeah so you know as it is uh net uh
28:22
know yeah so you know as it is uh net uh as it is in fully built on top of the
28:25
as it is in fully built on top of the
28:26
as it is in fully built on top of the net and we have a Microsoft community so
28:28
net and we have a Microsoft community so
28:28
net and we have a Microsoft community so you know for long-term projects you know
28:30
you know for long-term projects you know
28:30
you know for long-term projects you know it is suitable so you know these five
28:33
it is suitable so you know these five
28:33
it is suitable so you know these five factors I mentioned uh you know based on
28:36
factors I mentioned uh you know based on
28:36
factors I mentioned uh you know based on these these five factors you know we can
28:37
these these five factors you know we can
28:37
these these five factors you know we can adopt the blazer and you know the
28:41
adopt the blazer and you know the
28:41
adopt the blazer and you know the technical highlights basically you know
28:42
technical highlights basically you know
28:42
technical highlights basically you know uh I would like to highlight like you
28:44
uh I would like to highlight like you
28:44
uh I would like to highlight like you know blazer supports uh standard DOM
28:46
know blazer supports uh standard DOM
28:46
know blazer supports uh standard DOM events like you know on click on change
28:48
events like you know on click on change
28:48
events like you know on click on change and you know it also supports the custom
28:51
and you know it also supports the custom
28:51
and you know it also supports the custom events so the supported events are mouse
28:53
events so the supported events are mouse
28:54
events so the supported events are mouse events keyboard events events focus
28:56
events keyboard events events focus
28:56
events keyboard events events focus events and keyboard
28:58
events and keyboard
28:58
events and keyboard events like here I mentioned all uh the
29:02
events like here I mentioned all uh the
29:02
events like here I mentioned all uh the mouse events keyboard events so the
29:05
mouse events keyboard events so the
29:05
mouse events keyboard events so the event types you Say for example we have
29:07
event types you Say for example we have
29:07
event types you Say for example we have a button and we have an event called on
29:10
a button and we have an event called on
29:10
a button and we have an event called on click. So we'll mention at the rate on
29:13
click. So we'll mention at the rate on
29:13
click. So we'll mention at the rate on click and that particular method name
29:15
click and that particular method name
29:15
click and that particular method name and uh in the C# code we'll write the
29:17
and uh in the C# code we'll write the
29:17
and uh in the C# code we'll write the particular
29:19
particular
29:19
particular logic. So this is how we'll handle the
29:21
logic. So this is how we'll handle the
29:21
logic. So this is how we'll handle the events and uh the validations also you
29:25
events and uh the validations also you
29:25
events and uh the validations also you know it is pretty much easy. It supports
29:27
know it is pretty much easy. It supports
29:27
know it is pretty much easy. It supports the data annotations. So we'll open a
29:30
the data annotations. So we'll open a
29:30
the data annotations. So we'll open a tag edit form and we'll bind the model
29:34
tag edit form and we'll bind the model
29:34
tag edit form and we'll bind the model and we'll you know mention onv validate
29:38
and we'll you know mention onv validate
29:38
and we'll you know mention onv validate submit onv valid submit basically so
29:41
submit onv valid submit basically so
29:41
submit onv valid submit basically so where we'll call the data annotations to
29:44
where we'll call the data annotations to
29:44
where we'll call the data annotations to validate that particular model which we
29:46
validate that particular model which we
29:46
validate that particular model which we have b. So in the validation summary tag
29:49
have b. So in the validation summary tag
29:49
have b. So in the validation summary tag we'll get the validation error.
29:52
we'll get the validation error.
29:52
we'll get the validation error. So we'll have different different
29:55
So we'll have different different
29:55
So we'll have different different validations right you know the required
29:57
validations right you know the required
29:57
validations right you know the required range all other
30:00
range all other
30:01
range all other uh data annotations will be supported by
30:05
uh data annotations will be supported by
30:05
uh data annotations will be supported by blazer and we have JS interoptability.
30:08
blazer and we have JS interoptability.
30:08
blazer and we have JS interoptability. So Blazer allows calling JavaScript from
30:11
So Blazer allows calling JavaScript from
30:11
So Blazer allows calling JavaScript from C# vice versa like you know from C# also
30:14
C# vice versa like you know from C# also
30:14
C# vice versa like you know from C# also you know we can call the JavaScript from
30:15
you know we can call the JavaScript from
30:16
you know we can call the JavaScript from JavaScript also you know we can call the
30:18
JavaScript also you know we can call the
30:18
JavaScript also you know we can call the uh C# method. So we Microsoft provides
30:22
uh C# method. So we Microsoft provides
30:22
uh C# method. So we Microsoft provides IGS runtime to invoke JavaScript
30:25
IGS runtime to invoke JavaScript
30:25
IGS runtime to invoke JavaScript functions from C#. Say for example you
30:27
functions from C#. Say for example you
30:27
functions from C#. Say for example you know in the code we can write JS runtime
30:30
know in the code we can write JS runtime
30:30
know in the code we can write JS runtime invoke async and then the method name
30:34
invoke async and then the method name
30:34
invoke async and then the method name and we'll pass the attributes. If you
30:37
and we'll pass the attributes. If you
30:37
and we'll pass the attributes. If you want to call the C#
30:39
want to call the C#
30:39
want to call the C# method in JavaScript on top of the
30:42
method in JavaScript on top of the
30:42
method in JavaScript on top of the method we need to add JS invocable
30:45
method we need to add JS invocable
30:45
method we need to add JS invocable attribute. So in this way we can call
30:47
attribute. So in this way we can call
30:47
attribute. So in this way we can call the JavaScript
30:49
the JavaScript
30:49
the JavaScript interoperability. So uh when it comes to
30:52
interoperability. So uh when it comes to
30:52
interoperability. So uh when it comes to third party tools so
30:55
third party tools so
30:55
third party tools so the other advantage I am seeing is you
30:58
the other advantage I am seeing is you
30:58
the other advantage I am seeing is you know we have lot of components
31:01
know we have lot of components
31:01
know we have lot of components opensource components that are
31:04
opensource components that are
31:04
opensource components that are available in
31:07
available in
31:07
available in uh you know available for blazer. So we
31:09
uh you know available for blazer. So we
31:09
uh you know available for blazer. So we have mud blazer, raden, microsoft tools.
31:13
have mud blazer, raden, microsoft tools.
31:13
have mud blazer, raden, microsoft tools. You know these three are basically the
31:16
You know these three are basically the
31:16
You know these three are basically the key players which are
31:18
key players which are
31:18
key players which are offering you know very beautiful and use
31:23
offering you know very beautiful and use
31:23
offering you know very beautiful and use userfriendly components. So raden and
31:26
userfriendly components. So raden and
31:26
userfriendly components. So raden and mud blazer are widely used and Microsoft
31:29
mud blazer are widely used and Microsoft
31:29
mud blazer are widely used and Microsoft is started giving the uh are building
31:32
is started giving the uh are building
31:32
is started giving the uh are building the you know the components for the
31:33
the you know the components for the
31:33
the you know the components for the blazer. So I I mentioned the links. I
31:36
blazer. So I I mentioned the links. I
31:36
blazer. So I I mentioned the links. I don't want to open them. Uh but you know
31:38
don't want to open them. Uh but you know
31:38
don't want to open them. Uh but you know uh yeah let me open uh
31:41
uh yeah let me open uh
31:41
uh yeah let me open uh one. So in
31:47
Mudblazer you see we have a different
31:50
Mudblazer you see we have a different
31:50
Mudblazer you see we have a different different components
31:53
different components
31:53
different components uh that are here. So you know uh all
31:57
uh that are here. So you know uh all
31:57
uh that are here. So you know uh all these are different different components
31:59
these are different different components
31:59
these are different different components that when and that we can use them
32:01
that when and that we can use them
32:01
that when and that we can use them directly uh by using or you know by
32:05
directly uh by using or you know by
32:05
directly uh by using or you know by invoking um that particular blazer
32:08
invoking um that particular blazer
32:08
invoking um that particular blazer library or the new get package into our
32:10
library or the new get package into our
32:10
library or the new get package into our project and also
32:15
uh yeah before the conclusion so I would
32:18
uh yeah before the conclusion so I would
32:18
uh yeah before the conclusion so I would like to you know cover the benefits
32:20
like to you know cover the benefits
32:20
like to you know cover the benefits limitations and uh challenges part. to
32:23
limitations and uh challenges part. to
32:23
limitations and uh challenges part. to uh I'm comparing the blazer server app,
32:26
uh I'm comparing the blazer server app,
32:26
uh I'm comparing the blazer server app, blazer web assembly and the blazer
32:28
blazer web assembly and the blazer
32:28
blazer web assembly and the blazer hybrid. Uh so I would like to you know
32:31
hybrid. Uh so I would like to you know
32:31
hybrid. Uh so I would like to you know talk about the benefits of blazer server
32:33
talk about the benefits of blazer server
32:34
talk about the benefits of blazer server app. So
32:36
app. So
32:36
app. So uh blazer server app basically you know
32:38
uh blazer server app basically you know
32:38
uh blazer server app basically you know it it
32:39
it it
32:39
it it it is fast initial load times. So uh it
32:45
it is fast initial load times. So uh it
32:45
it is fast initial load times. So uh it is not like web assembly. So it will
32:48
is not like web assembly. So it will
32:48
is not like web assembly. So it will start you know the application very
32:50
start you know the application very
32:50
start you know the application very fastly. So the initial load times is
32:52
fastly. So the initial load times is
32:52
fastly. So the initial load times is less when compared with blazer web
32:55
less when compared with blazer web
32:55
less when compared with blazer web assembly and the download size is
32:57
assembly and the download size is
32:57
assembly and the download size is significantly small when compared with
32:59
significantly small when compared with
32:59
significantly small when compared with web assembly and uh the server side
33:00
web assembly and uh the server side
33:00
web assembly and uh the server side execution reducing the client side sorry
33:04
execution reducing the client side sorry
33:04
execution reducing the client side sorry client resource usage when it comes to
33:06
client resource usage when it comes to
33:06
client resource usage when it comes to the benefits of blazer web assembly you
33:08
the benefits of blazer web assembly you
33:08
the benefits of blazer web assembly you know runs directly in the browser
33:10
know runs directly in the browser
33:10
know runs directly in the browser offline capabilities you know whereas in
33:13
offline capabilities you know whereas in
33:13
offline capabilities you know whereas in the blazer server app we don't have the
33:15
the blazer server app we don't have the
33:15
the blazer server app we don't have the you know uh the offline capabilities
33:18
you know uh the offline capabilities
33:18
you know uh the offline capabilities every time it the signal communicates
33:20
every time it the signal communicates
33:20
every time it the signal communicates with the server it uses the C# instead
33:24
with the server it uses the C# instead
33:24
with the server it uses the C# instead of
33:25
of
33:25
of JavaScript. So these are the major
33:27
JavaScript. So these are the major
33:27
JavaScript. So these are the major benefits of u web assembly. So when it
33:31
benefits of u web assembly. So when it
33:31
benefits of u web assembly. So when it comes to blazer hybrid it offers the
33:34
comes to blazer hybrid it offers the
33:34
comes to blazer hybrid it offers the crossplatform support mobile desktop and
33:36
crossplatform support mobile desktop and
33:36
crossplatform support mobile desktop and web and also it offers full access to
33:39
web and also it offers full access to
33:39
web and also it offers full access to native device and capabilities the reuse
33:42
native device and capabilities the reuse
33:42
native device and capabilities the reuse of web UI components across the
33:45
of web UI components across the
33:45
of web UI components across the platforms. So those are the uh you know
33:48
platforms. So those are the uh you know
33:48
platforms. So those are the uh you know main benefits of blazer hybrid. When it
33:52
main benefits of blazer hybrid. When it
33:52
main benefits of blazer hybrid. When it comes to the limitations uh as it is a
33:56
comes to the limitations uh as it is a
33:56
comes to the limitations uh as it is a uh as blazer server heavily depends on
33:58
uh as blazer server heavily depends on
33:58
uh as blazer server heavily depends on the signaler we'll have a higher latency
34:01
the signaler we'll have a higher latency
34:01
the signaler we'll have a higher latency due to network
34:03
due to network
34:03
due to network ops. So for every user action uh it will
34:07
ops. So for every user action uh it will
34:07
ops. So for every user action uh it will try to communicate to the server through
34:10
try to communicate to the server through
34:10
try to communicate to the server through signal. So which causes higher latency
34:12
signal. So which causes higher latency
34:12
signal. So which causes higher latency due to you know the network costs the
34:15
due to you know the network costs the
34:15
due to you know the network costs the scalability concerns with the main you
34:17
scalability concerns with the main you
34:18
scalability concerns with the main you know many concurrent users. So if you
34:19
know many concurrent users. So if you
34:19
know many concurrent users. So if you have you know concurrent users
34:22
have you know concurrent users
34:22
have you know concurrent users definitely the network latency will be
34:25
definitely the network latency will be
34:25
definitely the network latency will be high and you know we'll have the at
34:27
high and you know we'll have the at
34:27
high and you know we'll have the at least you know I have seen these
34:28
least you know I have seen these
34:28
least you know I have seen these scalability concerns and it requires
34:30
scalability concerns and it requires
34:30
scalability concerns and it requires constant server connection. So if the
34:33
constant server connection. So if the
34:33
constant server connection. So if the server is down unlike web assembly it
34:36
server is down unlike web assembly it
34:36
server is down unlike web assembly it won't offer the offline capability.
34:39
won't offer the offline capability.
34:39
won't offer the offline capability. when it comes to the limitations of
34:40
when it comes to the limitations of
34:40
when it comes to the limitations of blazer web assembly the larger initial
34:45
blazer web assembly the larger initial
34:45
blazer web assembly the larger initial download size. So it will give an uh
34:50
download size. So it will give an uh
34:50
download size. So it will give an uh uncomfortable or you know uh the unuser
34:54
uncomfortable or you know uh the unuser
34:54
uncomfortable or you know uh the unuser friendly experience to the user. So uh
34:59
friendly experience to the user. So uh
34:59
friendly experience to the user. So uh larger initial download size is you know
35:01
larger initial download size is you know
35:01
larger initial download size is you know one limitation that we cannot avoid and
35:04
one limitation that we cannot avoid and
35:04
one limitation that we cannot avoid and also the restricted to browser
35:06
also the restricted to browser
35:06
also the restricted to browser capabilities. So as it is you know the
35:08
capabilities. So as it is you know the
35:08
capabilities. So as it is you know the web assembly advantage is offline
35:10
web assembly advantage is offline
35:10
web assembly advantage is offline capabilities but somehow you know uh it
35:13
capabilities but somehow you know uh it
35:13
capabilities but somehow you know uh it will restrict two browser capabilities.
35:15
will restrict two browser capabilities.
35:15
will restrict two browser capabilities. So if the browser is not supporting some
35:18
So if the browser is not supporting some
35:18
So if the browser is not supporting some capability the blazer is also you know
35:21
capability the blazer is also you know
35:21
capability the blazer is also you know not supporting that particular
35:23
not supporting that particular
35:23
not supporting that particular capability it's a restriction basically
35:25
capability it's a restriction basically
35:25
capability it's a restriction basically and also the performance issues with the
35:27
and also the performance issues with the
35:27
and also the performance issues with the complex C# code
35:29
complex C# code
35:29
complex C# code uh so you know your program has lot of
35:33
uh so you know your program has lot of
35:33
uh so you know your program has lot of complexity on the UI on the user
35:35
complexity on the UI on the user
35:35
complexity on the UI on the user interaction so it causes you know the
35:38
interaction so it causes you know the
35:38
interaction so it causes you know the performance issues and also uh the
35:41
performance issues and also uh the
35:41
performance issues and also uh the limitations
35:42
limitations
35:42
limitations of blazer hybrid is uh is you know the
35:46
of blazer hybrid is uh is you know the
35:46
of blazer hybrid is uh is you know the separate native client apps must be
35:48
separate native client apps must be
35:48
separate native client apps must be built and maintained per each
35:51
built and maintained per each
35:51
built and maintained per each platform. So the web so we may have uh
35:54
platform. So the web so we may have uh
35:54
platform. So the web so we may have uh the same components can be used in uh
35:57
the same components can be used in uh
35:58
the same components can be used in uh you know different different
35:59
you know different different
35:59
you know different different crossplatforms but we need to maintain
36:01
crossplatforms but we need to maintain
36:01
crossplatforms but we need to maintain them separately. platform dependent
36:04
them separately. platform dependent
36:04
them separately. platform dependent components and styles also you know
36:07
components and styles also you know
36:07
components and styles also you know giving maintainability pro problems and
36:11
giving maintainability pro problems and
36:11
giving maintainability pro problems and longer download and install times
36:13
longer download and install times
36:13
longer download and install times compared to uh web apps. So it is uh you
36:18
compared to uh web apps. So it is uh you
36:18
compared to uh web apps. So it is uh you know it offers longer download and
36:20
know it offers longer download and
36:20
know it offers longer download and install uh times. The challenges I have
36:23
install uh times. The challenges I have
36:23
install uh times. The challenges I have noticed with the bler server app is the
36:26
noticed with the bler server app is the
36:26
noticed with the bler server app is the connection stability in poor network
36:27
connection stability in poor network
36:27
connection stability in poor network conditions because it it requires uh the
36:31
conditions because it it requires uh the
36:31
conditions because it it requires uh the constant server connection right. So the
36:33
constant server connection right. So the
36:33
constant server connection right. So the connection stability in poor network
36:34
connection stability in poor network
36:34
connection stability in poor network conditions is a challenge and server
36:37
conditions is a challenge and server
36:37
conditions is a challenge and server resource management for multiple users
36:39
resource management for multiple users
36:40
resource management for multiple users and
36:40
and
36:41
and uh uh for multiple users and handling
36:44
uh uh for multiple users and handling
36:44
uh uh for multiple users and handling temporary network interruptions will be
36:46
temporary network interruptions will be
36:46
temporary network interruptions will be a challenge and blazer web assembly. So
36:49
a challenge and blazer web assembly. So
36:50
a challenge and blazer web assembly. So you know initially we'll see the slow
36:53
you know initially we'll see the slow
36:53
you know initially we'll see the slow initial load times deployment issues
36:56
initial load times deployment issues
36:56
initial load times deployment issues like file
36:57
like file
36:57
like file corruption you know um and also the
37:00
corruption you know um and also the
37:00
corruption you know um and also the compatibility issues. So when it comes
37:02
compatibility issues. So when it comes
37:02
compatibility issues. So when it comes to blazer hybrid uh the managing the
37:05
to blazer hybrid uh the managing the
37:05
to blazer hybrid uh the managing the real time and large scale data is an
37:07
real time and large scale data is an
37:07
real time and large scale data is an challenge and optimizing UI rendering
37:09
challenge and optimizing UI rendering
37:10
challenge and optimizing UI rendering for large data sets is a challenge and
37:12
for large data sets is a challenge and
37:12
for large data sets is a challenge and uh you know offline support and data
37:14
uh you know offline support and data
37:14
uh you know offline support and data synchronization is also you know a
37:16
synchronization is also you know a
37:16
synchronization is also you know a challenge when we adopted bler hybrid
37:19
challenge when we adopted bler hybrid
37:19
challenge when we adopted bler hybrid but apart of all these things you know
37:21
but apart of all these things you know
37:21
but apart of all these things you know uh it has reasons to adopt and it has
37:25
uh it has reasons to adopt and it has
37:25
uh it has reasons to adopt and it has you know uh cases when to adopt the
37:27
you know uh cases when to adopt the
37:27
you know uh cases when to adopt the blazer. So you know on conclusion s like
37:30
blazer. So you know on conclusion s like
37:30
blazer. So you know on conclusion s like you know uh blazer unifies web desktop
37:34
you know uh blazer unifies web desktop
37:34
you know uh blazer unifies web desktop and mobile development for net
37:36
and mobile development for net
37:36
and mobile development for net developers. It is mainly for net
37:38
developers. It is mainly for net
37:38
developers. It is mainly for net developers. Now it simplifies the net
37:40
developers. Now it simplifies the net
37:40
developers. Now it simplifies the net developer life uh to develop the web
37:43
developer life uh to develop the web
37:43
developer life uh to develop the web applications and growing the adoption
37:45
applications and growing the adoption
37:45
applications and growing the adoption and Microsoft backing uh its moment a
37:49
and Microsoft backing uh its moment a
37:49
and Microsoft backing uh its moment a key player in shaping the future of web
37:53
key player in shaping the future of web
37:53
key player in shaping the future of web development. So this is all about
37:56
development. So this is all about
37:56
development. So this is all about blazer. So any questions for me?
38:08
Thanks Chandu. Uh that was a very crisp
38:09
Thanks Chandu. Uh that was a very crisp
38:09
Thanks Chandu. Uh that was a very crisp session. We have a few questions in the
38:11
session. We have a few questions in the
38:11
session. We have a few questions in the in the chat. Uh let's take them because
38:13
in the chat. Uh let's take them because
38:13
in the chat. Uh let's take them because we have about 10 minutes before we move
38:15
we have about 10 minutes before we move
38:15
we have about 10 minutes before we move to the next session. Um this first one
38:17
to the next session. Um this first one
38:17
to the next session. Um this first one coming from okay ledger says hello from
38:20
coming from okay ledger says hello from
38:20
coming from okay ledger says hello from Africa. I know he's I can see up there.
38:24
Africa. I know he's I can see up there.
38:24
Africa. I know he's I can see up there. So maybe let's take first from Sharma
38:27
So maybe let's take first from Sharma
38:27
So maybe let's take first from Sharma Sakshi. She's asking well I think she's
38:31
Sakshi. She's asking well I think she's
38:31
Sakshi. She's asking well I think she's a Gen Z. She's asking what are the
38:33
a Gen Z. She's asking what are the
38:33
a Gen Z. She's asking what are the biggest advantages Blazer offer over
38:35
biggest advantages Blazer offer over
38:35
biggest advantages Blazer offer over traditional JavaScript framework like
38:36
traditional JavaScript framework like
38:36
traditional JavaScript framework like React and Angular. I I love React. I
38:39
React and Angular. I I love React. I
38:39
React and Angular. I I love React. I don't mind working with React.
38:42
don't mind working with React.
38:42
don't mind working with React. Right. So you know if you are a C#
38:44
Right. So you know if you are a C#
38:45
Right. So you know if you are a C# developer so you know you no need to
38:48
developer so you know you no need to
38:48
developer so you know you no need to learn JavaScript or you know TypeScript
38:51
learn JavaScript or you know TypeScript
38:51
learn JavaScript or you know TypeScript anything you can directly develop the
38:53
anything you can directly develop the
38:53
anything you can directly develop the web application and also you know it has
38:56
web application and also you know it has
38:56
web application and also you know it has a backup of Microsoft so the
38:59
a backup of Microsoft so the
38:59
a backup of Microsoft so the maintainability is very easy and also uh
39:03
maintainability is very easy and also uh
39:03
maintainability is very easy and also uh unlike the reactor or angler we have uh
39:08
unlike the reactor or angler we have uh
39:08
unlike the reactor or angler we have uh very standard or you know very good
39:10
very standard or you know very good
39:10
very standard or you know very good community support. So like I mentioned
39:13
community support. So like I mentioned
39:13
community support. So like I mentioned you know the mud blazer or the rad see
39:16
you know the mud blazer or the rad see
39:16
you know the mud blazer or the rad see we have multiple components that are
39:18
we have multiple components that are
39:18
we have multiple components that are available. So you know you can able to
39:21
available. So you know you can able to
39:21
available. So you know you can able to build a complex web application directly
39:23
build a complex web application directly
39:23
build a complex web application directly by you know consuming those
39:27
by you know consuming those
39:27
by you know consuming those components. So I say you know it is very
39:31
components. So I say you know it is very
39:31
components. So I say you know it is very easy for net developer to develop in web
39:33
easy for net developer to develop in web
39:33
easy for net developer to develop in web application. That is one of the biggest
39:35
application. That is one of the biggest
39:35
application. That is one of the biggest advantage. And the second advantage is
39:37
advantage. And the second advantage is
39:37
advantage. And the second advantage is you know the components that has uh you
39:39
you know the components that has uh you
39:39
you know the components that has uh you know that blazer
39:41
know that blazer
39:41
know that blazer has and you know the maintainability.
39:43
has and you know the maintainability.
39:43
has and you know the maintainability. Yeah. Yeah. That's right. I mean I'm
39:45
Yeah. Yeah. That's right. I mean I'm
39:45
Yeah. Yeah. That's right. I mean I'm with you when you say you know it's it's
39:47
with you when you say you know it's it's
39:47
with you when you say you know it's it's it's a piece of cake for folks who are
39:49
it's a piece of cake for folks who are
39:49
it's a piece of cake for folks who are already into the C and ecosystem. They
39:52
already into the C and ecosystem. They
39:52
already into the C and ecosystem. They don't have they don't have to learn
39:53
don't have they don't have to learn
39:53
don't have they don't have to learn anything new. But if you are if you are
39:55
anything new. But if you are if you are
39:55
anything new. But if you are if you are if you are not in the Microsoft
39:57
if you are not in the Microsoft
39:57
if you are not in the Microsoft ecosystem right and then you think of
39:59
ecosystem right and then you think of
39:59
ecosystem right and then you think of learning blazer that that might have a
40:01
learning blazer that that might have a
40:01
learning blazer that that might have a learning curve and you might feel like
40:03
learning curve and you might feel like
40:03
learning curve and you might feel like why are using C and that that may be a
40:06
why are using C and that that may be a
40:06
why are using C and that that may be a little obstacle right maybe that maybe
40:09
little obstacle right maybe that maybe
40:09
little obstacle right maybe that maybe is stopping you to learn blazer but yeah
40:11
is stopping you to learn blazer but yeah
40:11
is stopping you to learn blazer but yeah if if you are working on C# then why not
40:15
if if you are working on C# then why not
40:15
if if you are working on C# then why not right there's no harm in trying okay
40:18
right there's no harm in trying okay
40:18
right there's no harm in trying okay perfect uh there's another question
40:20
perfect uh there's another question
40:20
perfect uh there's another question coming in from Rohit he's asking um What
40:23
coming in from Rohit he's asking um What
40:23
coming in from Rohit he's asking um What are the biggest challenges you have seen
40:26
are the biggest challenges you have seen
40:26
are the biggest challenges you have seen teams face when adopting Blazer and how
40:28
teams face when adopting Blazer and how
40:28
teams face when adopting Blazer and how can they overcome?
40:31
can they overcome?
40:31
can they overcome? So that's a very big uh you know
40:32
So that's a very big uh you know
40:32
So that's a very big uh you know question. So you know uh the challenge
40:35
question. So you know uh the challenge
40:35
question. So you know uh the challenge yeah the challenges uh we noticed is you
40:38
yeah the challenges uh we noticed is you
40:38
yeah the challenges uh we noticed is you know
40:40
know
40:40
know um choosing you know either mud blazer
40:43
um choosing you know either mud blazer
40:43
um choosing you know either mud blazer or you know components creation
40:45
or you know components creation
40:45
or you know components creation basically and educating the team right
40:48
basically and educating the team right
40:48
basically and educating the team right so no one you know is everyone is new to
40:51
so no one you know is everyone is new to
40:51
so no one you know is everyone is new to blazer uh so educating them and you know
40:54
blazer uh so educating them and you know
40:54
blazer uh so educating them and you know we have learning but u for a net
40:58
we have learning but u for a net
40:58
we have learning but u for a net developer it is pretty much easy but uh
41:01
developer it is pretty much easy but uh
41:01
developer it is pretty much easy but uh you know while adopting the blazer
41:03
you know while adopting the blazer
41:03
you know while adopting the blazer uh you know
41:04
uh you know
41:04
uh you know the we have seen like you know whenever
41:07
the we have seen like you know whenever
41:07
the we have seen like you know whenever we have a poor network connectivity
41:10
we have a poor network connectivity
41:10
we have a poor network connectivity right so it will always pop up saying
41:12
right so it will always pop up saying
41:12
right so it will always pop up saying that you know it is
41:14
that you know it is
41:14
that you know it is disconnected when we develop the
41:16
disconnected when we develop the
41:16
disconnected when we develop the applications using you know the server
41:18
applications using you know the server
41:18
applications using you know the server because it continuously pull the server
41:21
because it continuously pull the server
41:21
because it continuously pull the server with the help of signal but you know on

an high level you know I'm not I haven't
41:26
an high level you know I'm not I haven't seen any challenges you know we are
41:29
seen any challenges you know we are
41:29
seen any challenges you know we are using teric basically you know the teric
41:31
using teric basically you know the teric
41:31
using teric basically you know the teric components
41:32
components
41:32
components Okay. So as we are using the teleric
41:34
Okay. So as we are using the teleric
41:34
Okay. So as we are using the teleric components to build the enterprise
41:36
components to build the enterprise
41:36
components to build the enterprise application. So we haven't seen any you
41:38
application. So we haven't seen any you
41:38
application. So we haven't seen any you know uh uh major challenges but you know
41:42
know uh uh major challenges but you know
41:42
know uh uh major challenges but you know we are enjoying developing the
41:43
we are enjoying developing the
41:43
we are enjoying developing the application with blazer because it is
41:45
application with blazer because it is
41:45
application with blazer because it is pretty much easy when compared with you
41:48
pretty much easy when compared with you
41:48
pretty much easy when compared with you know the react or you know the other
41:50
know the react or you know the other
41:50
know the react or you know the other things.

things.
41:52
things. Yeah. Yeah that is right. Uh that is
41:54
Yeah. Yeah that is right. Uh that is
41:54
Yeah. Yeah that is right. Uh that is definitely right. And one thing you know
41:56
definitely right. And one thing you know
41:56
definitely right. And one thing you know that that always confuses me with baser
41:58
that that always confuses me with baser
41:58
that that always confuses me with baser you know I don't know why it is with
41:59
you know I don't know why it is with

you know I don't know why it is with baser I know people like to compare you
42:01
baser I know people like to compare you

but for blazer you got to decide is it a client side one or is it a server side
42:20
client side one or is it a server side
42:20
client side one or is it a server side one

one
42:22
one so why why do why do Microsoft has two
42:26
so why why do why do Microsoft has two
42:26
so why why do why do Microsoft has two flavors of Blazer. I don't get it.
42:30
flavors of Blazer. I don't get it.
42:30
flavors of Blazer. I don't get it. That is true. But uh yeah, that is true.
42:33
That is true. But uh yeah, that is true.
42:33
That is true. But uh yeah, that is true. But you know if you are trying to
42:36
But you know if you are trying to
42:36
But you know if you are trying to achieve or you know developing single
42:38
achieve or you know developing single
42:38
achieve or you know developing single page application you know the Microsoft
42:40
page application you know the Microsoft
42:40
page application you know the Microsoft document clearly says that you know we
42:42
document clearly says that you know we
42:42
document clearly says that you know we need to go with web assembly. If you are
42:45
need to go with web assembly. If you are
42:45
need to go with web assembly. If you are targeting you know multiple platforms
42:47
targeting you know multiple platforms
42:47
targeting you know multiple platforms you know the Microsoft documentation
42:49
you know the Microsoft documentation
42:49
you know the Microsoft documentation says go with net maui with blazer
42:51
says go with net maui with blazer
42:52
says go with net maui with blazer hybrid. Okay. So you know if your
42:54
hybrid. Okay. So you know if your
42:54
hybrid. Okay. So you know if your application requires you know multiple
42:56
application requires you know multiple
42:56
application requires you know multiple interaction support then you know go
42:59
interaction support then you know go
42:59
interaction support then you know go with blazer server app. I see you know
43:02
with blazer server app. I see you know
43:02
with blazer server app. I see you know pe lot of people adopting web assembly
43:05
pe lot of people adopting web assembly
43:05
pe lot of people adopting web assembly and net model rather than server app.
43:09
and net model rather than server app.
43:09
and net model rather than server app. Yeah. Yeah that's right. Web assembly is
43:11
Yeah. Yeah that's right. Web assembly is
43:11
Yeah. Yeah that's right. Web assembly is is more popular right than this. That
43:14
is more popular right than this. That
43:14
is more popular right than this. That that's that's very right. Okay we have a
43:16
that's that's very right. Okay we have a
43:16
that's that's very right. Okay we have a few more questions. Um there's another
43:18
few more questions. Um there's another
43:18
few more questions. Um there's another one coming from uh let's say Prolad Cha
43:21
one coming from uh let's say Prolad Cha
43:21
one coming from uh let's say Prolad Cha is asking do you see blazer eventually
43:23
is asking do you see blazer eventually
43:23
is asking do you see blazer eventually replacing JavaScript framework? I don't
43:25
replacing JavaScript framework? I don't
43:25
replacing JavaScript framework? I don't think that's going to happen in
43:26
think that's going to happen in
43:26
think that's going to happen in enterprise environment. What do you
43:28
enterprise environment. What do you
43:28
enterprise environment. What do you think it will complement them?
43:31
think it will complement them?
43:31
think it will complement them? I don't think so is going to take place.
43:33
I don't think so is going to take place.
43:33
I don't think so is going to take place. No, you know JavaScript won't be
43:36
No, you know JavaScript won't be

No, you know JavaScript won't be replaced by any other technology. Yeah.
43:39
replaced by any other technology. Yeah.
43:39
replaced by any other technology. Yeah. Right. So end of the day
43:42
Right. So end of the day
43:42
Right. So end of the day right? So end of the day the browser
43:44
right? So end of the day the browser
43:44
right? So end of the day the browser understands JavaScript. So if you
43:46
understands JavaScript. So if you
43:46
understands JavaScript. So if you develop your application you know in any
43:48
develop your application you know in any
43:48
develop your application you know in any other language you know whether it's in
43:50
other language you know whether it's in

44:02
That is 100% right. Right. Yeah. So and
44:02
That is 100% right. Right. Yeah. So and and if I'm not wrong right correct me if
44:04
and if I'm not wrong right correct me if
44:04
and if I'm not wrong right correct me if I'm wrong but the C# code that you're
44:06
I'm wrong but the C# code that you're

but you know as a practice we'll follow the clean architecture.
44:51
the clean architecture.
44:51
the clean architecture. Yeah. Simple and straight. Let's just
44:53
Yeah. Simple and straight. Let's just
44:53
Yeah. Simple and straight. Let's just stick to that.
44:55
stick to that.
44:55
stick to that. All right. I think there there's a few

uh we integrated multiple security
45:23
uh we integrated multiple security scraps within the CI/CD pipeline

black deck scan the vera code scan you
45:35
black deck scan the vera code scan you know sneak we we integrated all of them
45:38
know sneak we we integrated all of them
45:38
know sneak we we integrated all of them when we develop the applications in uh
45:42
when we develop the applications in uh
45:42
when we develop the applications in uh blazer but we haven't seen any you know
45:46
blazer but we haven't seen any you know
45:46
blazer but we haven't seen any you know security vulnerabilities when we develop
45:48
security vulnerabilities when we develop
45:48
security vulnerabilities when we develop the application with
45:49
the application with
45:49
the application with blazer right so you know we'll have a
45:52
blazer right so you know we'll have a
45:52
blazer right so you know we'll have a feeling that you know it is uh as it is
45:54
feeling that you know it is uh as it is
45:54
feeling that you know it is uh as it is you know uh downloaded to browser side
45:57
you know uh downloaded to browser side
45:57
you know uh downloaded to browser side you know it may cause security reasons
45:59
you know it may cause security reasons
45:59
you know it may cause security reasons It won't.

Yeah, I see your slides. I have added it to the stream and
50:07
to the stream and
50:07
to the stream and next next 15 to 17 minutes is all yours.
50:11
next next 15 to 17 minutes is all yours.
50:11
next next 15 to 17 minutes is all yours. Yeah. So hello all. So this session is
50:16
Yeah. So hello all. So this session is
50:16
Yeah. So hello all. So this session is about u efficient containerization of
50:19
about u efficient containerization of
50:20
about u efficient containerization of net application using net publish. So my
50:23
net application using net publish. So my
50:23
net application using net publish. So my name is I'm a Microsoft
50:26
name is I'm a Microsoft
50:26
name is I'm a Microsoft MVP. So uh first of all why we need to
50:32
MVP. So uh first of all why we need to
50:32
MVP. So uh first of all why we need to contain the deter application. So
50:34
contain the deter application. So
50:34
contain the deter application. So basically when we are
50:37
basically when we are
50:37
basically when we are um uh like developing and deploying
50:40
um uh like developing and deploying
50:40
um uh like developing and deploying application uh earier we used to mind
50:45
application uh earier we used to mind
50:45
application uh earier we used to mind okay if I'm building a net application
50:48
okay if I'm building a net application
50:48
okay if I'm building a net application is my host also contains the same
50:52
is my host also contains the same
50:52
is my host also contains the same version of the net installed on that
50:54
version of the net installed on that
50:54
version of the net installed on that machine or some if you are using some
50:57
machine or some if you are using some
50:57
machine or some if you are using some other dependencies we have to make sure
51:00
other dependencies we have to make sure
51:00
other dependencies we have to make sure that dependencies are already installed
51:02
that dependencies are already installed
51:02
that dependencies are already installed on that machine. So all those problems
51:06
on that machine. So all those problems
51:06
on that machine. So all those problems we were able to fix with docker
51:09
we were able to fix with docker
51:09
we were able to fix with docker container. So when docker introduced or
51:13
container. So when docker introduced or
51:14
container. So when docker introduced or containerization introduced in the net
51:16
containerization introduced in the net
51:16
containerization introduced in the net code we were uh we can just build the
51:20
code we were uh we can just build the
51:20
code we were uh we can just build the application and container and we will be
51:24
application and container and we will be
51:24
application and container and we will be able to deploy it to the source.
51:27
able to deploy it to the source.
51:27
able to deploy it to the source. So uh basically uh when I started my
51:31
So uh basically uh when I started my
51:31
So uh basically uh when I started my career I used to like say okay it's
51:34
career I used to like say okay it's
51:34
career I used to like say okay it's what's on my machine and my manager and
51:37
what's on my machine and my manager and
51:37
what's on my machine and my manager and lead used to say okay we are not
51:39
lead used to say okay we are not
51:39
lead used to say okay we are not shipping your machine to the client. So
51:42
shipping your machine to the client. So
51:42
shipping your machine to the client. So uh docker actually solves that problem
51:44
uh docker actually solves that problem
51:44
uh docker actually solves that problem by pulling everything abstracting
51:47
by pulling everything abstracting
51:47
by pulling everything abstracting everything into one or encapsulating
51:50
everything into one or encapsulating
51:50
everything into one or encapsulating every dependencies everything into a
51:52
every dependencies everything into a
51:52
every dependencies everything into a single unit and you can deploy that
51:55
single unit and you can deploy that
51:55
single unit and you can deploy that unit. So these are the various uh things
51:59
unit. So these are the various uh things
51:59
unit. So these are the various uh things why we need to conduct it. We'll be able
52:02
why we need to conduct it. We'll be able
52:02
why we need to conduct it. We'll be able to port the applications very easily
52:05
to port the applications very easily
52:05
to port the applications very easily between various environments. Uh we'll
52:08
between various environments. Uh we'll
52:08
between various environments. Uh we'll be able to scale. So for example, if I'm
52:11
be able to scale. So for example, if I'm
52:11
be able to scale. So for example, if I'm running an application in uh container,
52:14
running an application in uh container,
52:14
running an application in uh container, I'll be able to scale like say I want to
52:17
I'll be able to scale like say I want to
52:18
I'll be able to scale like say I want to run a pi instance of that
52:20
run a pi instance of that
52:20
run a pi instance of that application. I can just say okay my tail
52:24
application. I can just say okay my tail
52:24
application. I can just say okay my tail value is five. then I'll be able to run
52:27
value is five. then I'll be able to run
52:27
value is five. then I'll be able to run it in five
52:30
it in five
52:30
it in five different different instances and uh
52:34
different different instances and uh
52:34
different different instances and uh it's same line. So as a developer I can
52:38
it's same line. So as a developer I can
52:38
it's same line. So as a developer I can focus on okay building the application
52:41
focus on okay building the application
52:41
focus on okay building the application and I don't need to worry about okay in
52:43
and I don't need to worry about okay in
52:43
and I don't need to worry about okay in my server that dependency is there or
52:46
my server that dependency is there or
52:46
my server that dependency is there or the same version of net is installed on
52:48
the same version of net is installed on
52:48
the same version of net is installed on that I don't need to
52:51
that I don't need to
52:51
that I don't need to worry so uh when in when we starting uh
52:56
worry so uh when in when we starting uh
52:56
worry so uh when in when we starting uh like container we need to understand
53:00
like container we need to understand
53:00
like container we need to understand okay what all things we need to so we
53:03
okay what all things we need to so we
53:03
okay what all things we need to so we need in the traditional container
53:05
need in the traditional container
53:05
need in the traditional container session These are the challenge. So when
53:07
session These are the challenge. So when
53:07
session These are the challenge. So when we are developing a container, you need
53:10
we are developing a container, you need
53:10
we are developing a container, you need a specific file called docker docker
53:13
a specific file called docker docker
53:13
a specific file called docker docker file. So it is a set of instructions
53:17
file. So it is a set of instructions
53:17
file. So it is a set of instructions what all things you need to be part of
53:19
what all things you need to be part of
53:19
what all things you need to be part of that container
53:21
that container
53:21
that container image. So it is manual process like if
53:26
image. So it is manual process like if
53:26
image. So it is manual process like if you code you will be able to generate
53:29
you code you will be able to generate
53:30
you code you will be able to generate it. But still there are some challenges.
53:32
it. But still there are some challenges.
53:32
it. But still there are some challenges. For example, I'm building a web AP
53:34
For example, I'm building a web AP
53:34
For example, I'm building a web AP application file. I am adding a I
53:38
application file. I am adding a I
53:38
application file. I am adding a I created a docker file. Then I am adding
53:40
created a docker file. Then I am adding
53:40
created a docker file. Then I am adding a library as a dependency. Then I have
53:43
a library as a dependency. Then I have
53:43
a library as a dependency. Then I have to modify my docker file to adjust that
53:48
to modify my docker file to adjust that
53:48
to modify my docker file to adjust that also. I need to copy that. I need to
53:51
also. I need to copy that. I need to
53:51
also. I need to copy that. I need to update the build step to build that
53:54
update the build step to build that
53:54
update the build step to build that assembly. All those things it should be
53:56
assembly. All those things it should be
53:56
assembly. All those things it should be again
53:57
again
53:57
again updated. That is one issue. Second is uh
54:02
updated. That is one issue. Second is uh
54:02
updated. That is one issue. Second is uh we want you will be like we have to make
54:06
we want you will be like we have to make
54:06
we want you will be like we have to make sure that container runtime is installed
54:09
sure that container runtime is installed
54:09
sure that container runtime is installed on my machine. So if you're using docker
54:12
on my machine. So if you're using docker
54:12
on my machine. So if you're using docker or man or any other container runtime we
54:16
or man or any other container runtime we
54:16
or man or any other container runtime we have to make sure it is installed and uh
54:20
have to make sure it is installed and uh
54:20
have to make sure it is installed and uh since this is a virtualization
54:21
since this is a virtualization
54:21
since this is a virtualization technology uh either you have to
54:24
technology uh either you have to
54:24
technology uh either you have to install like uh this one WSL or
54:30
install like uh this one WSL or
54:30
install like uh this one WSL or virtualization hyperV so all those
54:32
virtualization hyperV so all those
54:32
virtualization hyperV so all those things matter so that we have to enable
54:36
things matter so that we have to enable
54:36
things matter so that we have to enable virtualization in your machine if it is
54:39
virtualization in your machine if it is
54:39
virtualization in your machine if it is notable.
54:41
notable.
54:41
notable. you won't be able to do that. You have
54:43
you won't be able to do that. You have
54:43
you won't be able to do that. You have to enable WSL all those things and in
54:47
to enable WSL all those things and in
54:47
to enable WSL all those things and in PCD we have conte more step for
54:51
PCD we have conte more step for
54:51
PCD we have conte more step for addressing the uh again docker has to be
54:54
addressing the uh again docker has to be
54:54
addressing the uh again docker has to be installed on the pip pipeline all those
54:58
installed on the pip pipeline all those
54:58
installed on the pip pipeline all those things and cheaper learning curve for
55:01
things and cheaper learning curve for
55:01
things and cheaper learning curve for vin so if you're a net developer and you
55:05
vin so if you're a net developer and you
55:05
vin so if you're a net developer and you have to learn one more thing like you
55:08
have to learn one more thing like you
55:08
have to learn one more thing like you need to understand uh yl you need to
55:12
need to understand uh yl you need to
55:12
need to understand uh yl you need to create docker files. uh you need to
55:15
create docker files. uh you need to
55:15
create docker files. uh you need to understand some uh like basics of Linux
55:20
understand some uh like basics of Linux
55:20
understand some uh like basics of Linux um and what are base images how layering
55:24
um and what are base images how layering
55:24
um and what are base images how layering works all those things it may be a
55:27
works all those things it may be a
55:27
works all those things it may be a little all working for a newcomer but it
55:31
little all working for a newcomer but it
55:31
little all working for a newcomer but it is there so
55:36
how team or Microsoft
55:40
how team or Microsoft
55:40
how team or Microsoft team resolve all these issues In from 6
55:44
team resolve all these issues In from 6
55:44
team resolve all these issues In from 6 onwards uh they introduce a new
55:47
onwards uh they introduce a new
55:47
onwards uh they introduce a new capability uh we can publish
55:51
capability uh we can publish
55:51
capability uh we can publish docker images or we can create docker
55:55
docker images or we can create docker
55:55
docker images or we can create docker images without any container uh
55:58
images without any container uh
55:58
images without any container uh container run. We can use the publish
56:03
container run. We can use the publish
56:03
container run. We can use the publish command to create
56:06
command to create
56:06
command to create a docker image without any
56:10
a docker image without any
56:10
a docker image without any uh no docker file container runtime if
56:14
uh no docker file container runtime if
56:14
uh no docker file container runtime if needed and it's very simple you just
56:17
needed and it's very simple you just
56:17
needed and it's very simple you just need to say
56:18
need to say
56:18
need to say docker you can create a project as a
56:22
docker you can create a project as a
56:22
docker you can create a project as a docker publish with a uh default profile
56:28
command and If you want to customize the
56:32
command and If you want to customize the
56:32
command and If you want to customize the uh docker image settings, you can modify
56:35
uh docker image settings, you can modify
56:35
uh docker image settings, you can modify the project file and
56:39
the project file and
56:39
the project file and update. So these are the
56:41
update. So these are the
56:41
update. So these are the prerequisites. Uh you need net SDK and
56:46
prerequisites. Uh you need net SDK and
56:46
prerequisites. Uh you need net SDK and container contain again it's optional.
56:49
container contain again it's optional.
56:49
container contain again it's optional. Uh if you already installed it, good. If
56:53
Uh if you already installed it, good. If
56:54
Uh if you already installed it, good. If you want to play around and you want to
56:57
you want to play around and you want to
56:57
you want to play around and you want to test it or u like
57:01
test it or u like
57:01
test it or u like uh run in locally all those things you
57:04
uh run in locally all those things you
57:04
uh run in locally all those things you need docker or man or any other
57:08
need docker or man or any other
57:08
need docker or man or any other container. Let's jump into the demo. I
57:12
container. Let's jump into the demo. I
57:12
container. Let's jump into the demo. I already created a
57:14
already created a
57:14
already created a uh web AP
57:17
uh web AP
57:17
uh web AP application. So it's nothing just plain
57:21
application. So it's nothing just plain
57:21
application. So it's nothing just plain old net web AP application enable
57:27
API
57:31
and then uh I am already running docker
57:35
and then uh I am already running docker
57:35
and then uh I am already running docker in my
57:38
machine but I don't have any images I
57:41
machine but I don't have any images I
57:41
machine but I don't have any images I don't have any
57:42
don't have any
57:42
don't have any containers so I'm just going to export
57:47
containers so I'm just going to export
57:47
containers so I'm just going to export this command
57:59
Uh this is uh everything is net 8. Uh it
58:03
Uh this is uh everything is net 8. Uh it
58:03
Uh this is uh everything is net 8. Uh it was uh from 6
58:06
was uh from 6
58:06
was uh from 6 onward. So it is building a image hello
58:10
onward. So it is building a image hello
58:10
onward. So it is building a image hello world that is the project name with a
58:13
world that is the project name with a
58:13
world that is the project name with a tag. Tag is basically version kind of
58:17
tag. Tag is basically version kind of
58:17
tag. Tag is basically version kind of thing. So tag latest on base image
58:22
thing. So tag latest on base image
58:22
thing. So tag latest on base image Microsoft D that is the like base image
58:28
Microsoft D that is the like base image
58:28
Microsoft D that is the like base image from that it it is actually the kind of
58:32
from that it it is actually the kind of
58:32
from that it it is actually the kind of for that. Okay. Now if I say
58:37
for that. Okay. Now if I say
58:37
for that. Okay. Now if I say docker go here and images you'll be able
58:41
docker go here and images you'll be able
58:41
docker go here and images you'll be able to see it created an
58:44
to see it created an
58:44
to see it created an image. Let's run it. Docker
58:48
image. Let's run it. Docker
58:48
image. Let's run it. Docker run let's
59:01
see. So it started as uh web server uh
59:06
see. So it started as uh web server uh
59:06
see. So it started as uh web server uh listening on port 80. I don't have any
59:09
listening on port 80. I don't have any

1:00:29
Now uh there are certain things all
1:00:29
Now uh there are certain things all these things are running on time
1:00:33
these things are running on time
1:00:33
these things are running on time machine but sometime if I'm publishing
1:00:37
machine but sometime if I'm publishing
1:00:37
machine but sometime if I'm publishing to a uh hub or docker hub or any
1:00:43
to a uh hub or docker hub or any
1:00:43
to a uh hub or docker hub or any container registry. So uh docker or
1:00:46
container registry. So uh docker or
1:00:46
container registry. So uh docker or container workflow is basically you
1:00:48
container workflow is basically you
1:00:48
container workflow is basically you create a container you publish it to a
1:00:52
create a container you publish it to a
1:00:52
create a container you publish it to a container registry and your op team or
1:00:56
container registry and your op team or
1:00:56
container registry and your op team or de deployment team takes that image or
1:01:00
de deployment team takes that image or
1:01:00
de deployment team takes that image or your whatever pipeline takes that image
1:01:04
your whatever pipeline takes that image
1:01:04
your whatever pipeline takes that image and deploys to the web of in natural uh
1:01:09
and deploys to the web of in natural uh
1:01:09
and deploys to the web of in natural uh it is after container and like contain
1:01:14
it is after container and like contain
1:01:14
it is after container and like contain that is
1:01:15
that is
1:01:15
that is offer.
1:01:16
offer.
1:01:16
offer. So if I want to publish to docker hub,
1:01:20
So if I want to publish to docker hub,
1:01:20
So if I want to publish to docker hub, I'm not using a container say I'm using
1:01:23
I'm not using a container say I'm using
1:01:23
I'm not using a container say I'm using docker hub. So in that scenario, I have
1:01:27
docker hub. So in that scenario, I have
1:01:27
docker hub. So in that scenario, I have to make sure that my container name
1:01:31
to make sure that my container name
1:01:31
to make sure that my container name instead of hello world it should be in
1:01:33
instead of hello world it should be in
1:01:34
instead of hello world it should be in the format of uh hub username that the
1:01:38
the format of uh hub username that the
1:01:38
the format of uh hub username that the image name application name. So if I
1:01:42
image name application name. So if I
1:01:42
image name application name. So if I want to customize that I just need to
1:01:45
want to customize that I just need to
1:01:45
want to customize that I just need to add a property like this container
1:01:48
add a property like this container
1:01:48
add a property like this container repository. This is my docker hub
1:01:50
repository. This is my docker hub
1:01:50
repository. This is my docker hub username and this is the
1:01:53
username and this is the
1:01:53
username and this is the application. And now if I do uh
1:02:08
this Oh, sorry. I didn't save
1:02:18
the Now it build a different image. So
1:02:23
the Now it build a different image. So
1:02:23
the Now it build a different image. So Android with the
1:02:25
Android with the
1:02:25
Android with the latest. Okay. Now if I come
1:02:29
latest. Okay. Now if I come
1:02:29
latest. Okay. Now if I come here, you'll be able to see
1:02:31
here, you'll be able to see
1:02:31
here, you'll be able to see Android. The same thing no other
1:02:35
Android. The same thing no other
1:02:35
Android. The same thing no other differences. And
1:02:37
differences. And
1:02:37
differences. And uh keeping uh the latest as version is
1:02:42
uh keeping uh the latest as version is
1:02:42
uh keeping uh the latest as version is not the recommended packing. So if I
1:02:46
not the recommended packing. So if I
1:02:46
not the recommended packing. So if I want to customize the tag, I can do it
1:02:49
want to customize the tag, I can do it
1:02:49
want to customize the tag, I can do it with contain tag.
1:02:53
with contain tag.
1:02:53
with contain tag. uh tag containment tag
1:02:56
uh tag containment tag
1:02:56
uh tag containment tag elements.
1:03:01
So
1:03:03
So
1:03:03
So here these are the various customization
1:03:06
here these are the various customization
1:03:06
here these are the various customization options. So I'm changing I added a
1:03:09
options. So I'm changing I added a
1:03:09
options. So I'm changing I added a version as V1. I'm keeping
1:03:13
version as V1. I'm keeping
1:03:13
version as V1. I'm keeping these things
1:03:16
up. Then I'm updating
1:03:29
again. Now it came as V1 tag. Earlier it
1:03:34
again. Now it came as V1 tag. Earlier it
1:03:34
again. Now it came as V1 tag. Earlier it was now it is
1:03:37
was now it is
1:03:37
was now it is V1. And
1:03:39
V1. And
1:03:39
V1. And uh so okay. So if you look into
1:03:43
uh so okay. So if you look into
1:03:43
uh so okay. So if you look into this you'll be able to see Debian and if
1:03:48
this you'll be able to see Debian and if
1:03:48
this you'll be able to see Debian and if I want to and it's almost 220 MB 220 MB.
1:03:54
I want to and it's almost 220 MB 220 MB.
1:03:54
I want to and it's almost 220 MB 220 MB. So if I want to reduce the size of that
1:03:59
So if I want to reduce the size of that
1:03:59
So if I want to reduce the size of that image I can use alpine image. So I am
1:04:06
image I can use alpine image. So I am
1:04:06
image I can use alpine image. So I am just changing it to alpine and I'm
1:04:09
just changing it to alpine and I'm
1:04:09
just changing it to alpine and I'm updating the tag as
1:04:11
updating the tag as
1:04:11
updating the tag as well. Now if I run this
1:04:28
again and if I go here that alane
1:04:32
again and if I go here that alane
1:04:32
again and if I go here that alane version got a smaller footprint. also
1:04:37
version got a smaller footprint. also
1:04:37
version got a smaller footprint. also 110 MB and it's
1:04:51
also uh registry. If I want to publish
1:04:54
also uh registry. If I want to publish
1:04:54
also uh registry. If I want to publish it to a different one, what I can do? I
1:04:59
it to a different one, what I can do? I
1:04:59
it to a different one, what I can do? I can uh like add a container registry
1:05:03
can uh like add a container registry
1:05:03
can uh like add a container registry which is the container you want. You can
1:05:05
which is the container you want. You can
1:05:06
which is the container you want. You can set
1:05:08
it. Yeah. Okay. This is the way you can
1:05:11
it. Yeah. Okay. This is the way you can
1:05:11
it. Yeah. Okay. This is the way you can run the
1:05:13
run the
1:05:13
run the container. And for deploying to docker
1:05:16
container. And for deploying to docker
1:05:16
container. And for deploying to docker hub you need to uh set these two
1:05:20
hub you need to uh set these two
1:05:20
hub you need to uh set these two environment container with the username
1:05:22
environment container with the username
1:05:22
environment container with the username and password.

1:07:12
Um I am publishing again.
1:07:17
Now hopefully it will get published
1:07:21
Now hopefully it will get published
1:07:21
Now hopefully it will get published to Yeah, it is actually getting

1:07:58
Yeah, these are some
1:08:24
No. So these are some best practices you
1:08:28
No. So these are some best practices you
1:08:28
No. So these are some best practices you can follow. Use physical or tags always
1:08:32
can follow. Use physical or tags always
1:08:32
can follow. Use physical or tags always don't use status
1:08:34
don't use status
1:08:34
don't use status uh monitor the image size. So you can
1:08:37
uh monitor the image size. So you can
1:08:37
uh monitor the image size. So you can optimize the alpha or any other images.
1:08:40
optimize the alpha or any other images.
1:08:40
optimize the alpha or any other images. You can do security scanning regularly
1:08:43
You can do security scanning regularly
1:08:43
You can do security scanning regularly scan images for all. So uh there are
1:08:46
scan images for all. So uh there are
1:08:46
scan images for all. So uh there are yeah this tab refers to the website. Uh

I'm going to dive into how to enhance an existing net project by adding uh the
1:19:29
existing net project by adding uh the

existing net project by adding uh the net aspire. So why I'm not going to
1:19:34
net aspire. So why I'm not going to

net aspire. So why I'm not going to introduce net aspire or getting started
1:19:37
introduce net aspire or getting started
1:19:37
introduce net aspire or getting started by um net aspire because if you do a
1:19:42
by um net aspire because if you do a
1:19:42
by um net aspire because if you do a little search on the internet YouTube or
1:19:45
little search on the internet YouTube or
1:19:45
little search on the internet YouTube or anywhere you will find many resources
1:19:49
anywhere you will find many resources
1:19:49
anywhere you will find many resources which all of them are talking about how
1:19:53
which all of them are talking about how
1:19:53
which all of them are talking about how to get started I mean how to create a
1:19:56
to get started I mean how to create a
1:19:56
to get started I mean how to create a new project
1:19:58
new project
1:19:58
new project uh in uh with Aspire
1:20:01
uh in uh with Aspire
1:20:01
uh in uh with Aspire Okay. But uh in a real world uh they're
1:20:05
Okay. But uh in a real world uh they're
1:20:05
Okay. But uh in a real world uh they're not going to start from scratch. Uh all
1:20:09
not going to start from scratch. Uh all
1:20:09
not going to start from scratch. Uh all companies they have their own uh
1:20:12
companies they have their own uh
1:20:12
companies they have their own uh projects right and they are working with
1:20:15
projects right and they are working with
1:20:15
projects right and they are working with clean architecture
1:20:17
clean architecture
1:20:17
clean architecture microservices and layer or or even
1:20:21
microservices and layer or or even
1:20:21
microservices and layer or or even simple uh web API MVC blazer or or any
1:20:26
simple uh web API MVC blazer or or any
1:20:26
simple uh web API MVC blazer or or any other uh applications. they're not going
1:20:29
other uh applications. they're not going
1:20:29
other uh applications. they're not going to delete their projects and stop from
1:20:33
to delete their projects and stop from
1:20:33
to delete their projects and stop from scratch. So the big deal is how can I
1:20:38
scratch. So the big deal is how can I
1:20:38
scratch. So the big deal is how can I integrate or
1:20:40
integrate or
1:20:40
integrate or uh add this new feature net aspire to my
1:20:46
uh add this new feature net aspire to my
1:20:46
uh add this new feature net aspire to my existing project. This is better than
1:20:49
existing project. This is better than
1:20:49
existing project. This is better than starting from scratch.
1:20:52
starting from scratch.
1:20:52
starting from scratch. So uh
1:20:55
So uh
1:20:55
So uh uh for example for u a sample I I have

updating creating delete and other uh operations. So and one more thing that
1:23:14
operations. So and one more thing that
1:23:14
operations. So and one more thing that I'm going to show here here is the
1:23:17
I'm going to show here here is the
1:23:17
I'm going to show here here is the connection stream. It's my connection
1:23:20
connection stream. It's my connection
1:23:20
connection stream. It's my connection string. And let's see what do we have in
1:23:24
string. And let's see what do we have in
1:23:24
string. And let's see what do we have in the program. CS the regular things that
1:23:29
the program. CS the regular things that
1:23:29
the program. CS the regular things that we usually use in our projects.
1:23:32
we usually use in our projects.
1:23:32
we usually use in our projects. Controllers, API
1:23:34
Controllers, API

1:23:48
others. And the another project that I
1:23:48
others. And the another project that I have is an MVC client project. That's an
1:23:52
have is an MVC client project. That's an
1:23:52
have is an MVC client project. That's an MVC which acts as uh client uh and uh
1:23:58
MVC which acts as uh client uh and uh
1:23:58
MVC which acts as uh client uh and uh its responsibility is uh showing or or
1:24:03
its responsibility is uh showing or or
1:24:03
its responsibility is uh showing or or uh interacting with my API project to uh
1:24:08
uh interacting with my API project to uh
1:24:08
uh interacting with my API project to uh make an interface for
1:24:13
make an interface for
1:24:13
make an interface for uh let's say our application. So if I
1:24:17
uh let's say our application. So if I
1:24:17
uh let's say our application. So if I need to run the application
1:24:21
need to run the application
1:24:21
need to run the application uh I need to
1:24:24
uh I need to
1:24:24
uh I need to uh run multiple projects because uh I
1:24:28
uh run multiple projects because uh I
1:24:28
uh run multiple projects because uh I need to run both projects at the same
1:24:32
need to run both projects at the same
1:24:32
need to run both projects at the same time and then when I press the run
1:24:36
time and then when I press the run
1:24:36
time and then when I press the run button let
1:24:38
button let
1:24:38
button let me
1:24:39
me
1:24:39
me see where it's going to
1:24:46
Um
1:24:58
yes. Okay. Great. So you can see that I
1:25:04
yes. Okay. Great. So you can see that I
1:25:04
yes. Okay. Great. So you can see that I have two projects starting. One is for
1:25:07
have two projects starting. One is for
1:25:07
have two projects starting. One is for my uh API project which is loading on
1:25:14
my uh API project which is loading on
1:25:14
my uh API project which is loading on 5,01
1:25:15
5,01
1:25:15
5,01 [Music]
1:25:17
[Music]
1:25:17
[Music] uh it's my API project and another one
1:25:20
uh it's my API project and another one
1:25:20
uh it's my API project and another one is my client application which uh in
1:25:23
is my client application which uh in
1:25:23
is my client application which uh in this case it's an MVC application.
1:25:28
this case it's an MVC application.
1:25:28
this case it's an MVC application. So uh of course you know that
1:25:32
So uh of course you know that
1:25:32
So uh of course you know that uh there are other solutions like using
1:25:36
uh there are other solutions like using
1:25:36
uh there are other solutions like using docker compose for
1:25:40
docker compose for
1:25:40
docker compose for uh converting my application to docker
1:25:43
uh converting my application to docker
1:25:43
uh converting my application to docker image and running them uh through
1:25:47
image and running them uh through
1:25:47
image and running them uh through docker. But uh here we now we have
1:25:53
docker. But uh here we now we have
1:25:53
docker. But uh here we now we have something like the despire
1:25:56
something like the despire
1:25:56
something like the despire which it helps to uh manage run uh log
1:26:04
which it helps to uh manage run uh log
1:26:04
which it helps to uh manage run uh log monitor and many other
1:26:06
monitor and many other
1:26:06
monitor and many other features to uh make it easy our lives.
1:26:12
features to uh make it easy our lives.
1:26:13
features to uh make it easy our lives. So
1:26:14
So
1:26:14
So uh in my project I'm using API uh MVC EF
1:26:20
uh in my project I'm using API uh MVC EF
1:26:20
uh in my project I'm using API uh MVC EF core as my OM
1:26:22
core as my OM
1:26:22
core as my OM uh but uh we are going to convert this
1:26:28
uh but uh we are going to convert this
1:26:28
uh but uh we are going to convert this project to an Aspire project or let me
1:26:32
project to an Aspire project or let me
1:26:32
project to an Aspire project or let me say uh add Aspire to the current
1:26:36
say uh add Aspire to the current
1:26:36
say uh add Aspire to the current project.
1:26:39
project.
1:26:39
project. So okay
1:26:42
So okay
1:26:42
So okay uh we're going to talk about what is
1:26:44
uh we're going to talk about what is
1:26:44
uh we're going to talk about what is Aspire and how it helps to developers.
1:26:48
Aspire and how it helps to developers.
1:26:48
Aspire and how it helps to developers. We are going to add uh net aspire to an
1:26:52
We are going to add uh net aspire to an
1:26:52
We are going to add uh net aspire to an existing project using visual studio of
1:26:55
existing project using visual studio of
1:26:55
existing project using visual studio of course and uh we we will see how to use
1:27:00
course and uh we we will see how to use
1:27:00
course and uh we we will see how to use pre-built packages in net aspire of
1:27:03
pre-built packages in net aspire of
1:27:03
pre-built packages in net aspire of course uh Microsoft provides uh some
1:27:07
course uh Microsoft provides uh some
1:27:07
course uh Microsoft provides uh some packages but uh they're
1:27:09
packages but uh they're
1:27:09
packages but uh they're not complete yet I mean uh we need more
1:27:14
not complete yet I mean uh we need more
1:27:14
not complete yet I mean uh we need more packages but of course is new and uh we
1:27:18
packages but of course is new and uh we
1:27:18
packages but of course is new and uh we need to wait for other tools to
1:27:23
need to wait for other tools to
1:27:23
need to wait for other tools to integrate with
1:27:26
integrate with
1:27:26
integrate with blaspire and we will see how we can use
1:27:32
blaspire and we will see how we can use
1:27:32
blaspire and we will see how we can use uh other tools and technologies that are
1:27:35
uh other tools and technologies that are
1:27:35
uh other tools and technologies that are not integrated with Aspire using uh
1:27:40
not integrated with Aspire using uh
1:27:40
not integrated with Aspire using uh container
1:27:42
container
1:27:42
container uh for unsupported tools and then uh I
1:27:46
uh for unsupported tools and then uh I
1:27:46
uh for unsupported tools and then uh I will just mention how to use Postgress
1:27:49
will just mention how to use Postgress
1:27:49
will just mention how to use Postgress instead of SQL server. I'm I'm using SQL
1:27:51
instead of SQL server. I'm I'm using SQL
1:27:51
instead of SQL server. I'm I'm using SQL server as a database but at the end I
1:27:55
server as a database but at the end I
1:27:55
server as a database but at the end I will add the uh
1:27:59
will add the uh
1:27:59
will add the uh Postgress uh as a database to uh to see
1:28:03
Postgress uh as a database to uh to see
1:28:03
Postgress uh as a database to uh to see how it
1:28:05
how it
1:28:05
how it works. So let's
1:28:08
works. So let's
1:28:08
works. So let's see what do we have here. Let me stop
1:28:13
see what do we have here. Let me stop
1:28:13
see what do we have here. Let me stop the projects and uh let me show one more
1:28:17
the projects and uh let me show one more
1:28:17
the projects and uh let me show one more thing.
1:28:19
thing.
1:28:19
thing. uh from my MVC
1:28:23
uh from my MVC
1:28:23
uh from my MVC client. Uh of course I have my
1:28:28
client. Uh of course I have my
1:28:28
client. Uh of course I have my controller which as you can see it
1:28:32
controller which as you can see it
1:28:32
controller which as you can see it represents or returns views for listing
1:28:37
represents or returns views for listing
1:28:38
represents or returns views for listing people for showing the detail of a
1:28:40
people for showing the detail of a
1:28:40
people for showing the detail of a people
1:28:42
people
1:28:42
people creating and update delete and other
1:28:45
creating and update delete and other
1:28:45
creating and update delete and other stuffs.
1:28:47
stuffs.
1:28:47
stuffs. So and one more thing is service. I
1:28:52
So and one more thing is service. I
1:28:52
So and one more thing is service. I wrote a helper generic HTTP service to
1:28:57
wrote a helper generic HTTP service to
1:28:57
wrote a helper generic HTTP service to communicate with my API
1:29:00
communicate with my API
1:29:00
communicate with my API uh with uh HTTP calls and as you can see
1:29:05
uh with uh HTTP calls and as you can see
1:29:05
uh with uh HTTP calls and as you can see I'm using HTTP client factory. Here I
1:29:08
I'm using HTTP client factory. Here I
1:29:08
I'm using HTTP client factory. Here I have methods like post
1:29:13
have methods like post
1:29:13
have methods like post async, get async,
1:29:16
async, get async,
1:29:16
async, get async, delete, update
1:29:18
delete, update
1:29:18
delete, update and send for general
1:29:22
and send for general
1:29:22
and send for general purpose. And if you take a look at my
1:29:27
purpose. And if you take a look at my
1:29:27
purpose. And if you take a look at my program.cs,
1:29:29
program.cs,
1:29:29
program.cs, uh I'm configuring the HTTP client here.
1:29:34
uh I'm configuring the HTTP client here.
1:29:34
uh I'm configuring the HTTP client here. uh I named it API and I am setting the
1:29:39
uh I named it API and I am setting the
1:29:39
uh I named it API and I am setting the base URL. Why I'm mentioning these
1:29:42
base URL. Why I'm mentioning these
1:29:42
base URL. Why I'm mentioning these details because we're going to uh see
1:29:46
details because we're going to uh see
1:29:46
details because we're going to uh see some magic stuff or really fantastic uh
1:29:51
some magic stuff or really fantastic uh
1:29:51
some magic stuff or really fantastic uh features that Aspire uh gives us.
1:29:56
features that Aspire uh gives us.
1:29:56
features that Aspire uh gives us. As you can see, I'm setting the base URL
1:29:59
As you can see, I'm setting the base URL
1:29:59
As you can see, I'm setting the base URL from my uh app settings which is local
1:30:03
from my uh app settings which is local
1:30:03
from my uh app settings which is local host with port
1:30:07
host with port
1:30:07
host with port 50001 right so I need to define exact
1:30:12
50001 right so I need to define exact
1:30:12
50001 right so I need to define exact port exact address and if I try to
1:30:16
port exact address and if I try to
1:30:16
port exact address and if I try to change something like the port or the
1:30:19
change something like the port or the
1:30:19
change something like the port or the address I need to change everywhere that
1:30:23
address I need to change everywhere that
1:30:23
address I need to change everywhere that I am using Right. So keep in mind this
1:30:27
I am using Right. So keep in mind this
1:30:27
I am using Right. So keep in mind this one because we will get back to this and
1:30:31
one because we will get back to this and
1:30:31
one because we will get back to this and the others
1:30:32
the others

books. Right. So now I'm going to decide to add net
1:30:43
So now I'm going to decide to add net
1:30:43
So now I'm going to decide to add net aspire to this existing project.
1:30:47

beautiful creating a solution directory
1:31:52
beautiful creating a solution directory
1:31:52
beautiful creating a solution directory or folder and put it in here. Okay. So
1:31:57
or folder and put it in here. Okay. So
1:31:57
or folder and put it in here. Okay. So as you can see this project app host
1:32:00
as you can see this project app host
1:32:00
as you can see this project app host project is bold and of course you know
1:32:05
project is bold and of course you know
1:32:05
project is bold and of course you know that when this is bold it means that my
1:32:08
that when this is bold it means that my
1:32:08
that when this is bold it means that my entry point or running project is this
1:32:11
entry point or running project is this
1:32:11
entry point or running project is this project.
1:32:15
uh after adding the uh aspire project to
1:32:21
uh after adding the uh aspire project to
1:32:21
uh after adding the uh aspire project to my project I I I I'm
1:32:25
my project I I I I'm
1:32:25
my project I I I I'm having two more projects. One is app
1:32:28
having two more projects. One is app
1:32:28
having two more projects. One is app host and another one is service default.
1:32:32
host and another one is service default.
1:32:32
host and another one is service default. App host project acts like an
1:32:36
App host project acts like an
1:32:36
App host project acts like an orchestrator. It means that if you have
1:32:40
orchestrator. It means that if you have
1:32:40
orchestrator. It means that if you have a database, if you have uh an API
1:32:44
a database, if you have uh an API
1:32:44
a database, if you have uh an API service, if you have a client, if you
1:32:47
service, if you have a client, if you
1:32:47
service, if you have a client, if you have a radius for caching, if you have
1:32:50
have a radius for caching, if you have
1:32:50
have a radius for caching, if you have any other services, this project is
1:32:55
any other services, this project is
1:32:55
any other services, this project is responsible for
1:32:58
responsible for
1:32:58
responsible for uh
1:32:59
uh
1:32:59
uh managing all other services. And if you
1:33:03
managing all other services. And if you
1:33:03
managing all other services. And if you take a look at the program.cs of appost
1:33:08
take a look at the program.cs of appost
1:33:08
take a look at the program.cs of appost project, that's truly simple. It's

project, that's truly simple. It's
1:33:11
project, that's truly simple. It's really simple. And you can see that uh
1:33:16
really simple. And you can see that uh
1:33:16
really simple. And you can see that uh by using add project extension method,
1:33:19
by using add project extension method,
1:33:19
by using add project extension method, I'm adding or it added
1:33:23
I'm adding or it added
1:33:23
I'm adding or it added alphabetically to the project my API
1:33:27
alphabetically to the project my API
1:33:27
alphabetically to the project my API project.
1:33:29
project.
1:33:29
project. And you might ask question how it
1:33:35
And you might ask question how it
1:33:35
And you might ask question how it uh recognize that I have a project
1:33:40
uh recognize that I have a project
1:33:40
uh recognize that I have a project called
1:33:41
called
1:33:41

1:34:10
you can see, I'm just referencing to the
1:34:10
you can see, I'm just referencing to the API project. And if
1:34:13
API project. And if
1:34:13
API project. And if I add more
1:34:16
I add more
1:34:16
I add more reference like adding reference to the
1:34:19
reference like adding reference to the
1:34:19
reference like adding reference to the MVC client
1:34:22
MVC client
1:34:22
MVC client uh it will recognize it here and let's
1:34:27
uh it will recognize it here and let's
1:34:27
uh it will recognize it here and let's see just
1:34:32
for check that currently it's not
1:34:37
for check that currently it's not
1:34:37
for check that currently it's not recognizing my MVC client as you can See
1:34:42
recognizing my MVC client as you can See
1:34:42
recognizing my MVC client as you can See the here I just have project API the
1:34:47
the here I just have project API the
1:34:47
the here I just have project API the project that I uh reference to that one.
1:34:52
project that I uh reference to that one.
1:34:52
project that I uh reference to that one. Okay. So let's just comment this one and
1:34:57
Okay. So let's just comment this one and
1:34:58
Okay. So let's just comment this one and reference
1:34:59
reference
1:34:59
reference to MVC client. Uh there are multiple
1:35:03
to MVC client. Uh there are multiple
1:35:03
to MVC client. Uh there are multiple ways. uh one is right clicking on the
1:35:07
ways. uh one is right clicking on the
1:35:07
ways. uh one is right clicking on the MVC project and do the same process like
1:35:13
MVC project and do the same process like
1:35:13
MVC project and do the same process like this add Aspire orchestrator support.
1:35:17
this add Aspire orchestrator support.
1:35:17
this add Aspire orchestrator support. Another one is drag and drop to the uh
1:35:21
Another one is drag and drop to the uh
1:35:21
Another one is drag and drop to the uh to to the app host project and another
1:35:25
to to the app host project and another
1:35:25
to to the app host project and another one is simply writing
1:35:29
one is simply writing
1:35:29
one is simply writing uh the reference here. uh it doesn't
1:35:33
uh the reference here. uh it doesn't
1:35:33
uh the reference here. uh it doesn't matter which way you are doing but I'm
1:35:36
matter which way you are doing but I'm
1:35:36
matter which way you are doing but I'm using
1:35:38
using
1:35:38
using uh the menu that
1:35:41
uh the menu that
1:35:41
uh the menu that uh visual studio provides and as you can
1:35:45
uh visual studio provides and as you can
1:35:45
uh visual studio provides and as you can see it's added to my app host project.
1:35:51
see it's added to my app host project.
1:35:51
see it's added to my app host project. So let's get back to the program.cs
1:35:55
So let's get back to the program.cs
1:35:55
So let's get back to the program.cs project and
1:35:56
project and
1:35:56
project and uncomment
1:35:59
this and Here you go. You can see that
1:36:04
this and Here you go. You can see that
1:36:04
this and Here you go. You can see that MVPC client is added to projects list.
1:36:10
MVPC client is added to projects list.
1:36:10
MVPC client is added to projects list. Right?
1:36:19
So this is the definition of the
1:36:22
So this is the definition of the
1:36:22
So this is the definition of the projects that
1:36:24
projects that
1:36:24
projects that uh we see here.
1:36:27
uh we see here.
1:36:27
uh we see here. And you can see that the
1:36:33
uh yeah project
1:36:36
uh yeah project
1:36:36
uh yeah project pass it's changed. Okay, no problem. So
1:36:41
pass it's changed. Okay, no problem. So
1:36:41
pass it's changed. Okay, no problem. So and let me call this one
1:36:47
client and for simplicity let me remove
1:36:52
client and for simplicity let me remove
1:36:52
client and for simplicity let me remove the project from the beginning of that.
1:36:56
the project from the beginning of that.
1:36:56
the project from the beginning of that. Okay. So I have two projects. One API
1:37:00
Okay. So I have two projects. One API
1:37:00
Okay. So I have two projects. One API and another one is the client
1:37:03
and another one is the client
1:37:03
and another one is the client application. Okay. So
1:37:07
application. Okay. So
1:37:07
application. Okay. So uh I can do some more things. For
1:37:13
uh I can do some more things. For
1:37:13
uh I can do some more things. For example, for example,
1:37:15
example, for example,
1:37:15
example, for example, uh I want to not start the client
1:37:22
uh I want to not start the client
1:37:22
uh I want to not start the client application before starting a API.
1:37:27
application before starting a API.
1:37:27
application before starting a API. Right? For example, uh I need to wait I
1:37:31
Right? For example, uh I need to wait I
1:37:31
Right? For example, uh I need to wait I need to wait to run the API project.
1:37:36
need to wait to run the API project.
1:37:36
need to wait to run the API project. Simply I can use wait for and here I
1:37:42
Simply I can use wait for and here I
1:37:42
Simply I can use wait for and here I can give a name like API to this one and
1:37:47
can give a name like API to this one and
1:37:47
can give a name like API to this one and let's call
1:37:49
let's call
1:37:49
let's call this
1:37:54
client by providing or using this
1:37:57
client by providing or using this
1:37:57
client by providing or using this extension method I'm telling to my
1:38:01
extension method I'm telling to my
1:38:01
extension method I'm telling to my application or the data pier that hey
1:38:05
application or the data pier that hey
1:38:05
application or the data pier that hey wait and do not run the client
1:38:08
wait and do not run the client
1:38:08
wait and do not run the client application until the API application is
1:38:13
application until the API application is
1:38:13
application until the API application is run. And also I can do a
1:38:21
reference to my uh web API project. And
1:38:27
reference to my uh web API project. And
1:38:27
reference to my uh web API project. And if I need to use another things like the
1:38:31
if I need to use another things like the
1:38:31
if I need to use another things like the databases, the containers or anything
1:38:34
databases, the containers or anything
1:38:34
databases, the containers or anything else simply I can use builder
1:38:38
else simply I can use builder
1:38:38
else simply I can use builder dot add for example
1:38:41
dot add for example
1:38:41
dot add for example container which we will see
1:38:46
container which we will see
1:38:46
container which we will see uh next minutes how to use uh
1:38:50
uh next minutes how to use uh
1:38:50
uh next minutes how to use uh unsupported tools like or for example
1:38:55
unsupported tools like or for example
1:38:55
unsupported tools like or for example your client application is not a net
1:38:58
your client application is not a net
1:38:58
your client application is not a net application like Blazer or MVC. It's a
1:39:01
application like Blazer or MVC. It's a
1:39:01
application like Blazer or MVC. It's a react application. So what what should I
1:39:04
react application. So what what should I
1:39:04
react application. So what what should I do at that case? In that case, you can
1:39:08
do at that case? In that case, you can
1:39:08
do at that case? In that case, you can turn your
1:39:10
turn your
1:39:10
turn your uh react application to a docker image
1:39:14
uh react application to a docker image
1:39:14
uh react application to a docker image and simply use add container to run that
1:39:18
and simply use add container to run that
1:39:18
and simply use add container to run that one.
1:39:21
So
1:39:23
So
1:39:23
So uh the net aspire is a new feature from
1:39:27
uh the net aspire is a new feature from
1:39:27
uh the net aspire is a new feature from Microsoft designed to simplify building
1:39:31
Microsoft designed to simplify building
1:39:31
Microsoft designed to simplify building cloud native distributed applications.
1:39:35
cloud native distributed applications.
1:39:35
cloud native distributed applications. So it's going to uh make us uh make the
1:39:41
So it's going to uh make us uh make the
1:39:41
So it's going to uh make us uh make the working with cloud
1:39:45
working with cloud
1:39:45
working with cloud um easy. Right? So uh and and and
1:39:51
um easy. Right? So uh and and and
1:39:51
um easy. Right? So uh and and and the good part or important part is that
1:39:56
the good part or important part is that
1:39:56
the good part or important part is that it sits top of the net. This is the net
1:40:01
it sits top of the net. This is the net
1:40:01
it sits top of the net. This is the net and the net aspire is going to uh sit on
1:40:05
and the net aspire is going to uh sit on
1:40:05
and the net aspire is going to uh sit on top of the net because it's going to
1:40:08
top of the net because it's going to
1:40:08
top of the net because it's going to wrap up all my application my old
1:40:12
wrap up all my application my old
1:40:12
wrap up all my application my old application and
1:40:14
application and
1:40:14
application and uh and then I can use everything that I
1:40:19
uh and then I can use everything that I
1:40:19
uh and then I can use everything that I was using uh I was using like the
1:40:23
was using uh I was using like the

1:40:56
postress like radies like EF core but still it needs to be
1:41:00
still it needs to be
1:41:00
still it needs to be uh create more packages because still we
1:41:04
uh create more packages because still we

packages for connecting to database to using cache system and cloud services.
1:42:10
using cache system and cloud services.
1:42:10
using cache system and cloud services. For example, if you are using Azure
1:42:12
For example, if you are using Azure
1:42:12
For example, if you are using Azure monitor, you can simply by writing two
1:42:16
monitor, you can simply by writing two

1:42:59
some metrics.
1:42:59
some metrics. So
1:43:04
uh
1:43:06
uh
1:43:06
uh imagine we're working on a project with
1:43:08
imagine we're working on a project with
1:43:08
imagine we're working on a project with an API, a front end and a database.
1:43:13
an API, a front end and a database.
1:43:13
an API, a front end and a database. Normally we spend time configuring each

1:43:25
that
1:43:25
that Aspire automates this.
1:43:29
Aspire automates this.
1:43:29
Aspire automates this. Remember
1:43:30
Remember
1:43:30
Remember I showed that I'm using this URL, right?
1:43:37
I showed that I'm using this URL, right?
1:43:37
I showed that I'm using this URL, right? I showed that I am
1:43:42
I showed that I am
1:43:42
I showed that I am using this connection string,
1:43:46
using this connection string,
1:43:46
using this connection string, right? But by using spire all of these
1:43:50
right? But by using spire all of these
1:43:50
right? But by using spire all of these are going to be automated. I mean I'm
1:43:54
are going to be automated. I mean I'm
1:43:54
are going to be automated. I mean I'm going to configure to be configured
1:43:58
going to configure to be configured
1:43:58
going to configure to be configured automated. So this is really nice. It's
1:44:02
automated. So this is really nice. It's
1:44:02
automated. So this is really nice. It's like having a development time system
1:44:05
like having a development time system
1:44:05
like having a development time system that sets up your
1:44:07
that sets up your
1:44:07
that sets up your environment and enforces best practices
1:44:11
environment and enforces best practices
1:44:11
environment and enforces best practices because I'm not going to write code. It
1:44:14
because I'm not going to write code. It
1:44:14
because I'm not going to write code. It is implementing all uh codes,
1:44:18
is implementing all uh codes,
1:44:18
is implementing all uh codes, configurations and other stuffs by
1:44:21
configurations and other stuffs by
1:44:21
configurations and other stuffs by itself. And of course it's using the
1:44:23
itself. And of course it's using the
1:44:23
itself. And of course it's using the best practice and let's uh it it led me
1:44:28
best practice and let's uh it it led me
1:44:28
best practice and let's uh it it led me to focus on coding not not
1:44:33
to focus on coding not not

1:44:47
using for our API and MVC project that you can see it can simply uh simplify my
1:44:51
you can see it can simply uh simplify my
1:44:51
you can see it can simply uh simplify my service discovery. It means that uh if
1:44:55
service discovery. It means that uh if
1:44:56
service discovery. It means that uh if you pay attention I didn't do anything I
1:44:58
you pay attention I didn't do anything I
1:44:58
you pay attention I didn't do anything I just added my project or reference my

just added my project or reference my project to app that's enough and this is
1:45:08
project to app that's enough and this is
1:45:08
project to app that's enough and this is acting like a service discovery I don't
1:45:12
acting like a service discovery I don't
1:45:12
acting like a service discovery I don't need to use any other package or other
1:45:15
need to use any other package or other
1:45:15
need to use any other package or other tools as a service discovery by writing
1:45:19
tools as a service discovery by writing
1:45:19
tools as a service discovery by writing these lines of code it's
1:45:22
these lines of code it's

1:45:35
debugging and prepare us for cloud
1:45:35
debugging and prepare us for cloud deployment.
1:45:37
deployment.
1:45:37
deployment. uh because
1:45:39
uh because
1:45:39
uh because uh if you remember I when I ran the
1:45:45
uh if you remember I when I ran the
1:45:45
uh if you remember I when I ran the project
1:45:46
project
1:45:46
project uh I had two
1:45:48
uh I had two
1:45:48
uh I had two terminals which I could see the logs of
1:45:52
terminals which I could see the logs of
1:45:52
terminals which I could see the logs of my both applications separated in two
1:45:56
my both applications separated in two
1:45:56
my both applications separated in two terminals right but uh and and imagine
1:46:00
terminals right but uh and and imagine
1:46:00
terminals right but uh and and imagine if you have for example 10 API services
1:46:04
if you have for example 10 API services
1:46:04
if you have for example 10 API services and two other services, one database,
1:46:09
and two other services, one database,
1:46:09
and two other services, one database, another one for uh radius, another one
1:46:13
another one for uh radius, another one
1:46:13
another one for uh radius, another one for postgress and other stuffs, right?
1:46:17
for postgress and other stuffs, right?
1:46:17
for postgress and other stuffs, right? So, how many terminals or logging
1:46:22
So, how many terminals or logging
1:46:22
So, how many terminals or logging uh output you should check for checking
1:46:26
uh output you should check for checking
1:46:26
uh output you should check for checking the logs.
1:46:28
the logs.
1:46:28
the logs. But inn net aspire I'm going to have uh
1:46:33
But inn net aspire I'm going to have uh
1:46:33
But inn net aspire I'm going to have uh very simple uh or one place to see the
1:46:38
very simple uh or one place to see the
1:46:38
very simple uh or one place to see the logs of all
1:46:41
logs of all
1:46:41
logs of all uh services. So
1:46:50
uh yeah that's it. Uh okay so uh I
1:46:55
uh yeah that's it. Uh okay so uh I
1:46:55
uh yeah that's it. Uh okay so uh I talked about the app host and uh let's
1:46:59
talked about the app host and uh let's
1:46:59
talked about the app host and uh let's see what is service default. service
1:47:01
see what is service default. service
1:47:01
see what is service default. service fault is shared
1:47:03
fault is shared
1:47:03
fault is shared configurations for logging
1:47:06
configurations for logging
1:47:06
configurations for logging um and telery and uh the other stuffs
1:47:10
um and telery and uh the other stuffs
1:47:10
um and telery and uh the other stuffs that uh is shared between all
1:47:13
that uh is shared between all
1:47:13
that uh is shared between all applications as you can see I have a uh
1:47:17
applications as you can see I have a uh
1:47:17
applications as you can see I have a uh add service defaults here which is uh
1:47:20
add service defaults here which is uh
1:47:20
add service defaults here which is uh configuring my services like the service
1:47:23
configuring my services like the service
1:47:23
configuring my services like the service discovery like the uh health check like
1:47:28
discovery like the uh health check like
1:47:28
discovery like the uh health check like the open telementry and the others Okay.
1:47:30
the open telementry and the others Okay.
1:47:30
the open telementry and the others Okay. So, and uh because I'm out of time, I'm
1:47:35
So, and uh because I'm out of time, I'm
1:47:35
So, and uh because I'm out of time, I'm going to make it
1:47:37
going to make it
1:47:37
going to make it faster. So, uh yes, this is for health
1:47:42
faster. So, uh yes, this is for health
1:47:42
faster. So, uh yes, this is for health check and this one is for live and
1:47:46
check and this one is for live and
1:47:46
check and this one is for live and health URL. And for monitoring, if
1:47:50
health URL. And for monitoring, if
1:47:50
health URL. And for monitoring, if you're using
1:47:52
you're using
1:47:52
you're using uh Azure monitor, you can simply use
1:47:55
uh Azure monitor, you can simply use
1:47:55
uh Azure monitor, you can simply use this one.
1:47:59
And okay great. So
1:48:03
And okay great. So
1:48:03
And okay great. So uh just let
1:48:05
uh just let
1:48:05
uh just let me add one or two more things and I will
1:48:11
me add one or two more things and I will
1:48:11
me add one or two more things and I will uh uh finish my presentation. Okay.
1:48:17
uh uh finish my presentation. Okay.
1:48:17
uh uh finish my presentation. Okay. uh if you are using uh you know we are
1:48:22
uh if you are using uh you know we are
1:48:22
uh if you are using uh you know we are not using uhn net all the time we might
1:48:27
not using uhn net all the time we might
1:48:27
not using uhn net all the time we might use other services like radius like
1:48:31
use other services like radius like
1:48:31
use other services like radius like react like postgress like other services
1:48:35
react like postgress like other services
1:48:35
react like postgress like other services that are not uh the the netbased
1:48:40
that are not uh the the netbased
1:48:40
that are not uh the the netbased uh tools so what should I do uh for
1:48:45
uh tools so what should I do uh for
1:48:45
uh tools so what should I do uh for those situations
1:48:48
those situations
1:48:48
those situations uh we can use uh as I mentioned the the
1:48:53
uh we can use uh as I mentioned the the
1:48:53
uh we can use uh as I mentioned the the the dot add
1:48:57
the dot add
1:48:57
the dot add container and uh use the container right
1:49:01
container and uh use the container right
1:49:01
container and uh use the container right so
1:49:03
so
1:49:03
so uh or if I'm going to use the radius
1:49:07
uh or if I'm going to use the radius
1:49:07
uh or if I'm going to use the radius which is supported currently supported
1:49:10
which is supported currently supported
1:49:10
which is supported currently supported by
1:49:11
by
1:49:11
by uh Microsoft I can simply just add
1:49:20
uh Aspire
1:49:23
uh Aspire
1:49:23
uh Aspire package. It's nothing but just uh it's
1:49:27
package. It's nothing but just uh it's
1:49:27
package. It's nothing but just uh it's filtering uh the Aspire uh packages
1:49:31
filtering uh the Aspire uh packages
1:49:31
filtering uh the Aspire uh packages which you can see that I have the
1:49:34
which you can see that I have the
1:49:34
which you can see that I have the radies, I have the Postgress and the
1:49:38
radies, I have the Postgress and the
1:49:38
radies, I have the Postgress and the other stuffs. If you want to use this,
1:49:41
other stuffs. If you want to use this,
1:49:41
other stuffs. If you want to use this, it's really simple. You can just you
1:49:43
it's really simple. You can just you
1:49:43
it's really simple. You can just you need just add the
1:49:47
need just add the
1:49:47
need just add the postgress. Let me change the version
1:49:49
postgress. Let me change the version
1:49:49
postgress. Let me change the version because I'm using the version
1:49:55
9. And here we go. Builder add
1:50:00
9. And here we go. Builder add
1:50:00
9. And here we go. Builder add postgress. See that's
1:50:04
postgress. See that's
1:50:04
postgress. See that's simple. And also I can add the
1:50:08
simple. And also I can add the
1:50:08
simple. And also I can add the database for example
1:50:11
database for example
1:50:11
database for example people and of course because I'm using
1:50:14
people and of course because I'm using
1:50:14
people and of course because I'm using SQL server I need to change some
1:50:17
SQL server I need to change some
1:50:17
SQL server I need to change some configurations in my API project instead
1:50:21
configurations in my API project instead
1:50:21
configurations in my API project instead of using SQL server I need to use
1:50:24
of using SQL server I need to use
1:50:24
of using SQL server I need to use Postgress but I'm not going to uh go
1:50:27
Postgress but I'm not going to uh go
1:50:27
Postgress but I'm not going to uh go through into this because I'm
1:50:30
through into this because I'm
1:50:30
through into this because I'm pro time
1:50:35
And yeah, I think that's it. Oh, okay.
1:50:39
And yeah, I think that's it. Oh, okay.
1:50:40
And yeah, I think that's it. Oh, okay. So, for the last part, let's run the
1:50:44
So, for the last part, let's run the
1:50:44
So, for the last part, let's run the application to see what
1:50:46
application to see what
1:50:46
application to see what happens when we
1:50:51
use net Aspire or we add Aspire to the
1:50:57
use net Aspire or we add Aspire to the
1:50:57
use net Aspire or we add Aspire to the project.
1:51:14
previous. Okay, finally.
1:51:30
Great. So this is the dashboard of the
1:51:34
Great. So this is the dashboard of the

sure everything works fine, which is not going to work fine because I didn't
1:52:34
going to work fine because I didn't
1:52:34
going to work fine because I didn't change the
1:52:36
change the
1:52:36
change the address. Oh, it's working. But uh it's
1:52:40
address. Oh, it's working. But uh it's
1:52:40
address. Oh, it's working. But uh it's because uh it works with both of them.
1:52:44
because uh it works with both of them.
1:52:44
because uh it works with both of them. Uh as I
1:52:48
mentioned in here, I don't need to

1:54:07
It's coming from Oleg. He's saying can
1:54:07
It's coming from Oleg. He's saying can Aspire replace an existing uh net apps
1:54:10
Aspire replace an existing uh net apps
1:54:10
Aspire replace an existing uh net apps plus Kubernetes plus Docker ecosystem?
1:54:12
plus Kubernetes plus Docker ecosystem?
1:54:12
plus Kubernetes plus Docker ecosystem? That that's a pretty strong ecosystem to
1:54:14
That that's a pretty strong ecosystem to
1:54:14
That that's a pretty strong ecosystem to have. But can Aspire do it?
1:54:17
have. But can Aspire do it?
1:54:18
have. But can Aspire do it? uh in my opinion yes of course it can
1:54:23
uh in my opinion yes of course it can
1:54:23
uh in my opinion yes of course it can not today you know not today because as
1:54:27
not today you know not today because as
1:54:27
not today you know not today because as I mentioned in my presentation
1:54:30
I mentioned in my presentation
1:54:30
I mentioned in my presentation uh it's really

uh it's really uh young feature let's say young feature
1:54:37
uh young feature let's say young feature
1:54:37
uh young feature let's say young feature because you know the kubernetes the
1:54:38
because you know the kubernetes the
1:54:38
because you know the kubernetes the docker they're working many years of
1:54:43
docker they're working many years of
1:54:43
docker they're working many years of course and as uh I showed up in the
1:54:48
course and as uh I showed up in the
1:54:48
course and as uh I showed up in the aspire uh nougat packages. We had maybe
1:54:52
aspire uh nougat packages. We had maybe
1:54:52
aspire uh nougat packages. We had maybe 20 packages. Yeah. Yet, but in the
1:54:56
20 packages. Yeah. Yet, but in the
1:54:56
20 packages. Yeah. Yet, but in the future it will uh grow up and of course
1:55:00
future it will uh grow up and of course
1:55:00
future it will uh grow up and of course it can uh take the place of Kubernetes
1:55:05
it can uh take the place of Kubernetes
1:55:05
it can uh take the place of Kubernetes and Docker.
1:55:07
and Docker.
1:55:07
and Docker. Perfect. Thanks for that answer. I know
1:55:09
Perfect. Thanks for that answer. I know
1:55:09
Perfect. Thanks for that answer. I know a strong belief that Aspire can take it.

me here uh to the entire conference organizers and today I'll be speaking
1:58:05
organizers and today I'll be speaking
1:58:05
organizers and today I'll be speaking about synchronous web apps and how we
1:58:07
about synchronous web apps and how we
1:58:07
about synchronous web apps and how we can approach web apps from a messaging
1:58:10
can approach web apps from a messaging
1:58:10
can approach web apps from a messaging architecture point of view. You know as
1:58:13
architecture point of view. You know as
1:58:13
architecture point of view. You know as developers one of one of our greatest
1:58:16
developers one of one of our greatest
1:58:16
developers one of one of our greatest and perfect dreams is to get our hands
1:58:18
and perfect dreams is to get our hands
1:58:18
and perfect dreams is to get our hands dirty with code. I mean it mean what I
1:58:21
dirty with code. I mean it mean what I
1:58:21
dirty with code. I mean it mean what I mean by saying is that as developers
1:58:23
mean by saying is that as developers
1:58:23
mean by saying is that as developers nothing excites us than getting to work
1:58:25
nothing excites us than getting to work
1:58:25
nothing excites us than getting to work on a project with tons of integration
1:58:27
on a project with tons of integration
1:58:27
on a project with tons of integration patterns right creating databases
1:58:30
patterns right creating databases
1:58:30
patterns right creating databases entities defining workflows and if you
1:58:33
entities defining workflows and if you
1:58:33
entities defining workflows and if you have a ton of external APIs you know
1:58:36
have a ton of external APIs you know
1:58:36
have a ton of external APIs you know what let us just get through it you know
1:58:38
what let us just get through it you know
1:58:38
what let us just get through it you know you can't just wait to work on such a
1:58:40
you can't just wait to work on such a
1:58:40
you can't just wait to work on such a project sounds perfect right and I think
1:58:42
project sounds perfect right and I think
1:58:42
project sounds perfect right and I think that's a very relatable situation for
1:58:44
that's a very relatable situation for
1:58:44
that's a very relatable situation for all of us who are developers and it's a
1:58:47
all of us who are developers and it's a
1:58:47
all of us who are developers and it's a dream come true as well so We work on
1:58:49
dream come true as well so We work on
1:58:49
dream come true as well so We work on such projects and then we put our
1:58:52
such projects and then we put our
1:58:52
such projects and then we put our projects live. Fantastic. It's a moment
1:58:55
projects live. Fantastic. It's a moment
1:58:55
projects live. Fantastic. It's a moment of pride and joy when your project hits
1:58:58
of pride and joy when your project hits
1:58:58
of pride and joy when your project hits production and starts making money for
1:58:59
production and starts making money for
1:59:00
production and starts making money for the business. And there's no other joy
1:59:02
the business. And there's no other joy
1:59:02
the business. And there's no other joy like sh showcasing your own work. Again,
1:59:04
like sh showcasing your own work. Again,
1:59:04
like sh showcasing your own work. Again, something relatable. And then comes that
1:59:07
something relatable. And then comes that
1:59:07
something relatable. And then comes that first campaign that goes out as a mass

2:00:43
in the next 35 minutes we'll pick up
2:00:43
in the next 35 minutes we'll pick up some basics on asynchronous messaging
2:00:46
some basics on asynchronous messaging
2:00:46
some basics on asynchronous messaging and how we can use messaging as an
2:00:48
and how we can use messaging as an
2:00:48
and how we can use messaging as an architecture to have really high high
2:00:51
architecture to have really high high
2:00:51
architecture to have really high high throughput high performant mission
2:00:53
throughput high performant mission
2:00:53
throughput high performant mission critical systems and we'll see some code
2:00:56
critical systems and we'll see some code
2:00:56
critical systems and we'll see some code as well. When it comes to mission
2:00:58
as well. When it comes to mission
2:00:58
as well. When it comes to mission critical or high performance system, the
2:01:00
critical or high performance system, the
2:01:00
critical or high performance system, the the first thing I like to talk about is
2:01:02
the first thing I like to talk about is
2:01:02
the first thing I like to talk about is the order processing system. Why?
2:01:04
the order processing system. Why?
2:01:04
the order processing system. Why? Because it's a very relatable workflow
2:01:07
Because it's a very relatable workflow
2:01:07
Because it's a very relatable workflow for everyone. It is the holy grail when
2:01:09
for everyone. It is the holy grail when
2:01:09
for everyone. It is the holy grail when it comes to building distributed systems
2:01:11
it comes to building distributed systems
2:01:11
it comes to building distributed systems and talking about distributed systems.
2:01:13
and talking about distributed systems.
2:01:13
and talking about distributed systems. And what is a typical workflow? We go to
2:01:16
And what is a typical workflow? We go to
2:01:16
And what is a typical workflow? We go to the website, put a few products into the
2:01:18
the website, put a few products into the
2:01:18
the website, put a few products into the basket, click check out, put our details
2:01:21
basket, click check out, put our details
2:01:21
basket, click check out, put our details in, then fill in the credit card
2:01:23
in, then fill in the credit card
2:01:23
in, then fill in the credit card details, and then say place order. Boom.
2:01:26
details, and then say place order. Boom.
2:01:26
details, and then say place order. Boom. And that order goes into the backend
2:01:27
And that order goes into the backend
2:01:28
And that order goes into the backend system of the online shop. And then it
2:01:30
system of the online shop. And then it
2:01:30
system of the online shop. And then it gets processed. That's the happy day.
2:01:32
gets processed. That's the happy day.
2:01:32
gets processed. That's the happy day. That's not the rainy day. That's the
2:01:33
That's not the rainy day. That's the
2:01:33
That's not the rainy day. That's the sunny day that you can see just like the
2:01:36
sunny day that you can see just like the
2:01:36
sunny day that you can see just like the day I have out here in UK. That's a
2:01:38
day I have out here in UK. That's a
2:01:38
day I have out here in UK. That's a perfect case scenario. Now go back and
2:01:41
perfect case scenario. Now go back and
2:01:41
perfect case scenario. Now go back and rewind to that campaign scenario. Where
2:01:43
rewind to that campaign scenario. Where
2:01:43
rewind to that campaign scenario. Where were you at that point when you had that
2:01:45
were you at that point when you had that
2:01:45
were you at that point when you had that rainy day? So we had a sluggish day. Uh
2:01:50
rainy day? So we had a sluggish day. Uh
2:01:50
rainy day? So we had a sluggish day. Uh we had we started off with sluggish
2:01:52
we had we started off with sluggish
2:01:52
we had we started off with sluggish front ends. Sales are reported to be
2:01:54
front ends. Sales are reported to be
2:01:54
front ends. Sales are reported to be very low. Fine. You know what? We are on
2:01:57
very low. Fine. You know what? We are on
2:01:57
very low. Fine. You know what? We are on Azure. Let's just scale the front end.
2:01:59
Azure. Let's just scale the front end.
2:01:59
Azure. Let's just scale the front end. Autoscaling is what 10 minutes max.
2:02:02
Autoscaling is what 10 minutes max.
2:02:02
Autoscaling is what 10 minutes max. Fine, we do that. Have we solved the
2:02:04
Fine, we do that. Have we solved the
2:02:04
Fine, we do that. Have we solved the problem? Not yet. Because our backend
2:02:07
problem? Not yet. Because our backend
2:02:07
problem? Not yet. Because our backend services are struggling to cope up. It's
2:02:09
services are struggling to cope up. It's
2:02:09
services are struggling to cope up. It's still slow. Fine. We are going to
2:02:12
still slow. Fine. We are going to
2:02:12
still slow. Fine. We are going to autoscale our backend services. Now,
2:02:14
autoscale our backend services. Now,
2:02:14
autoscale our backend services. Now, there's a catch there. Legacy backends.
2:02:17
there's a catch there. Legacy backends.
2:02:17
there's a catch there. Legacy backends. Who has dealt with a backend system or
2:02:20
Who has dealt with a backend system or
2:02:20
Who has dealt with a backend system or API server hosted in a old server
2:02:23
API server hosted in a old server
2:02:23
API server hosted in a old server somewhere in the basement of a building
2:02:25
somewhere in the basement of a building
2:02:25
somewhere in the basement of a building been there done that there's an API
2:02:27
been there done that there's an API
2:02:27
been there done that there's an API which just couldn't be scaled that's a
2:02:29
which just couldn't be scaled that's a
2:02:29
which just couldn't be scaled that's a catch in itself let's just not talk
2:02:31
catch in itself let's just not talk
2:02:31
catch in itself let's just not talk about it but let us say that we have
2:02:33
about it but let us say that we have
2:02:33
about it but let us say that we have started scaling our backend services as
2:02:35
started scaling our backend services as
2:02:35
started scaling our backend services as well and then at one point we hit the
2:02:38
well and then at one point we hit the
2:02:38
well and then at one point we hit the wall the database so we have been moving
2:02:41
wall the database so we have been moving
2:02:41
wall the database so we have been moving the bottleneck from the front end to the
2:02:43
the bottleneck from the front end to the
2:02:43
the bottleneck from the front end to the backend services to the database then it
2:02:46
backend services to the database then it
2:02:46
backend services to the database then it just goes boom
2:02:47
just goes boom
2:02:47
just goes boom You know what? I cannot cope up with the
2:02:49
You know what? I cannot cope up with the
2:02:49
You know what? I cannot cope up with the amount of traffic that is hitting me,
2:02:51
amount of traffic that is hitting me,
2:02:51
amount of traffic that is hitting me, says the database. There's so much
2:02:53
says the database. There's so much
2:02:53
says the database. There's so much resources that you can throw at it. But
2:02:55
resources that you can throw at it. But
2:02:55
resources that you can throw at it. But what really happens is cascading
2:02:57
what really happens is cascading
2:02:57
what really happens is cascading failures. The database fails, it then
2:03:01
failures. The database fails, it then
2:03:01
failures. The database fails, it then goes and fails the backend services that
2:03:03
goes and fails the backend services that
2:03:03
goes and fails the backend services that we have scaled out and that goes and
2:03:05
we have scaled out and that goes and
2:03:05
we have scaled out and that goes and fails the sluggish front end which has
2:03:07
fails the sluggish front end which has
2:03:07
fails the sluggish front end which has also been scaled out horizontally,
2:03:09
also been scaled out horizontally,
2:03:09
also been scaled out horizontally, vertically, all way, but it then just
2:03:12
vertically, all way, but it then just
2:03:12
vertically, all way, but it then just blows up on the face of the user. we are
2:03:14
blows up on the face of the user. we are
2:03:14
blows up on the face of the user. we are not making money as a business and that
2:03:16
not making money as a business and that
2:03:16
not making money as a business and that is the rainy day that I've been talking
2:03:18
is the rainy day that I've been talking
2:03:18
is the rainy day that I've been talking about. Yeah. So I've been there done
2:03:20
about. Yeah. So I've been there done
2:03:20
about. Yeah. So I've been there done that myself years ago. So I was working
2:03:22
that myself years ago. So I was working
2:03:22
that myself years ago. So I was working on a system and when the mass email
2:03:25
on a system and when the mass email
2:03:25
on a system and when the mass email campaign went out to their very loyal
2:03:27
campaign went out to their very loyal
2:03:27
campaign went out to their very loyal customer base, we had like tons of
2:03:29
customer base, we had like tons of
2:03:29
customer base, we had like tons of people hitting the website and we had a
2:03:32
people hitting the website and we had a
2:03:32
people hitting the website and we had a legacy API and there was a point where I
2:03:35
legacy API and there was a point where I
2:03:35
legacy API and there was a point where I live monitored a system with my
2:03:37
live monitored a system with my
2:03:37
live monitored a system with my colleague over a phone call with a
2:03:39
colleague over a phone call with a
2:03:39
colleague over a phone call with a customer and that went on for a couple
2:03:41
customer and that went on for a couple
2:03:41
customer and that went on for a couple of rounds and that is where we start
2:03:43
of rounds and that is where we start
2:03:43
of rounds and that is where we start thinking about did I use the right tool
2:03:46
thinking about did I use the right tool
2:03:46
thinking about did I use the right tool for the project? You know could I have
2:03:49
for the project? You know could I have
2:03:49
for the project? You know could I have done this better? So what did I miss
2:03:52
done this better? So what did I miss
2:03:52
done this better? So what did I miss out? Did I miss a memo? And the memo
2:03:54
out? Did I miss a memo? And the memo
2:03:54
out? Did I miss a memo? And the memo that I missed out happens to be the
2:03:56
that I missed out happens to be the
2:03:56
that I missed out happens to be the policies of distributed computing. So
2:03:58
policies of distributed computing. So
2:03:58
policies of distributed computing. So what we have been speaking about so far
2:04:00
what we have been speaking about so far
2:04:00
what we have been speaking about so far is a distributed system where two or
2:04:03
is a distributed system where two or
2:04:03
is a distributed system where two or more computers speak to each other. So
2:04:05
more computers speak to each other. So
2:04:06
more computers speak to each other. So as developers when we develop
2:04:07
as developers when we develop
2:04:07
as developers when we develop distributed systems we take many many
2:04:10
distributed systems we take many many
2:04:10
distributed systems we take many many things for granted and those false
2:04:13
things for granted and those false
2:04:13
things for granted and those false assumptions have been coined together as
2:04:15
assumptions have been coined together as
2:04:15
assumptions have been coined together as the policies of distributed computing.
2:04:17
the policies of distributed computing.
2:04:17
the policies of distributed computing. the things which we failed to see up
2:04:19
the things which we failed to see up
2:04:19
the things which we failed to see up front. This was the this was this is a
2:04:22
front. This was the this was this is a
2:04:22
front. This was the this was this is a list of policies that was put together
2:04:24
list of policies that was put together
2:04:24
list of policies that was put together originally by Peter Deutsch. I will be
2:04:27
originally by Peter Deutsch. I will be
2:04:27
originally by Peter Deutsch. I will be leaving a link to all of this in my
2:04:28
leaving a link to all of this in my
2:04:28
leaving a link to all of this in my resources at the end. So keep on
2:04:30
resources at the end. So keep on
2:04:30
resources at the end. So keep on watching. But let us talk about these
2:04:33
watching. But let us talk about these
2:04:33
watching. But let us talk about these policies for a minute. We assume that
2:04:35
policies for a minute. We assume that
2:04:35
policies for a minute. We assume that the network is reliable. We assume that
2:04:37
the network is reliable. We assume that

network will always be up and network
2:04:41
network will always be up and network will everything that we send will be
2:04:43
will everything that we send will be
2:04:43
will everything that we send will be received. But in reality network can
2:04:45
received. But in reality network can
2:04:45
received. But in reality network can fail. information can get lost and
2:04:48
fail. information can get lost and
2:04:48
fail. information can get lost and network could become congested. Right?
2:04:50
network could become congested. Right?
2:04:50
network could become congested. Right? We assume that latency is zero. We
2:04:54
We assume that latency is zero. We
2:04:54
We assume that latency is zero. We assume that requests will complete
2:04:56
assume that requests will complete
2:04:56
assume that requests will complete instantly. But in reality there is
2:04:59
instantly. But in reality there is
2:04:59
instantly. But in reality there is always a delay millisecond, microsconds
2:05:01
always a delay millisecond, microsconds
2:05:01
always a delay millisecond, microsconds to even more in some cases. We assume
2:05:05
to even more in some cases. We assume
2:05:05
to even more in some cases. We assume that the bandwidth is infinite but
2:05:07
that the bandwidth is infinite but
2:05:07
that the bandwidth is infinite but bandwidth is finite. There's a limit to
2:05:09
bandwidth is finite. There's a limit to
2:05:09
bandwidth is finite. There's a limit to the bandwidth. You can have slowdowns
2:05:11
the bandwidth. You can have slowdowns
2:05:11
the bandwidth. You can have slowdowns and bottlenecks. We just cannot send as
2:05:14
and bottlenecks. We just cannot send as
2:05:14
and bottlenecks. We just cannot send as much data as we want at any
2:05:16
much data as we want at any
2:05:16
much data as we want at any point. We assume that the network is

point. We assume that the network is always secure. We assume that you know
2:05:23
always secure. We assume that you know
2:05:23
always secure. We assume that you know now my network is secure. There's no one
2:05:24
now my network is secure. There's no one
2:05:24
now my network is secure. There's no one coming to attack it. But we need to
2:05:26
coming to attack it. But we need to
2:05:26
coming to attack it. But we need to understand that in flight request
2:05:29
understand that in flight request
2:05:29
understand that in flight request there's always a chance that someone
2:05:31
there's always a chance that someone
2:05:31
there's always a chance that someone could intercept

could intercept
2:05:33
could intercept it. We assume that topology doesn't

2:05:36
it. We assume that topology doesn't change. We assume that servers, nodes,
2:05:39
change. We assume that servers, nodes,
2:05:39
change. We assume that servers, nodes, routes, they all are static and constant
2:05:41
routes, they all are static and constant
2:05:41
routes, they all are static and constant and they don't change. But in reality,
2:05:44
and they don't change. But in reality,
2:05:44
and they don't change. But in reality, machines crash, they restart, they get
2:05:46
machines crash, they restart, they get
2:05:46
machines crash, they restart, they get migrated, they scale up and down. So we
2:05:49
migrated, they scale up and down. So we
2:05:50
migrated, they scale up and down. So we cannot assume that there is no change.
2:05:52
cannot assume that there is no change.
2:05:52
cannot assume that there is no change. In fact, change is constant. And as
2:05:54
In fact, change is constant. And as
2:05:54
In fact, change is constant. And as developers, we need to embrace it. We
2:05:57
developers, we need to embrace it. We
2:05:57
developers, we need to embrace it. We assume that there's just a single
2:05:59
assume that there's just a single
2:05:59
assume that there's just a single administrator. But in reality, there is
2:06:01
administrator. But in reality, there is
2:06:01
administrator. But in reality, there is nothing called a centralized control.
2:06:03
nothing called a centralized control.
2:06:03
nothing called a centralized control. These days, it's more about distributed
2:06:05
These days, it's more about distributed
2:06:05
These days, it's more about distributed teams. You could have multiple teams
2:06:07
teams. You could have multiple teams
2:06:07
teams. You could have multiple teams working on the same distributed system
2:06:09
working on the same distributed system
2:06:09
working on the same distributed system and when that happens if you don't have
2:06:11
and when that happens if you don't have
2:06:11
and when that happens if you don't have enough inter team communication
2:06:13
enough inter team communication
2:06:13
enough inter team communication inconsistencies and failures happen but
2:06:15
inconsistencies and failures happen but
2:06:15
inconsistencies and failures happen but is there something called as enough
2:06:17
is there something called as enough
2:06:17
is there something called as enough interte communication I don't think
2:06:20
interte communication I don't think
2:06:21
interte communication I don't think so we assume that the transport cost is
2:06:24
so we assume that the transport cost is
2:06:24
so we assume that the transport cost is zero even if we have infinite bandwidth
2:06:27
zero even if we have infinite bandwidth
2:06:27
zero even if we have infinite bandwidth the transport cost is not zero you know
2:06:30
the transport cost is not zero you know
2:06:30
the transport cost is not zero you know there is a little bit of that extra that
2:06:31
there is a little bit of that extra that
2:06:32
there is a little bit of that extra that you pay at the end of every month with

you pay at the end of every month with your Azure bill that comes around that
2:06:36
your Azure bill that comes around that
2:06:36
your Azure bill that comes around that is what telling you is that transport
2:06:39
is what telling you is that transport
2:06:39
is what telling you is that transport cost is not zero. There's always cost
2:06:41
cost is not zero. There's always cost
2:06:41
cost is not zero. There's always cost associated even with CPU performance and
2:06:44
associated even with CPU performance and
2:06:44
associated even with CPU performance and usage. And we assume that network is
2:06:46
usage. And we assume that network is
2:06:46
usage. And we assume that network is homogeneous. But is the network
2:06:48
homogeneous. But is the network
2:06:48
homogeneous. But is the network homogeneous? Is the behavior always
2:06:50
homogeneous? Is the behavior always
2:06:50
homogeneous? Is the behavior always uniform? Never. Because no two systems
2:06:53
uniform? Never. Because no two systems
2:06:54
uniform? Never. Because no two systems or no two servers are
2:06:55
or no two servers are
2:06:55
or no two servers are alike. Let us go back to our order
2:06:58
alike. Let us go back to our order
2:06:58
alike. Let us go back to our order processing workflow and see what might
2:07:00
processing workflow and see what might
2:07:00
processing workflow and see what might the workflow be. So we have our website
2:07:03
the workflow be. So we have our website
2:07:03
the workflow be. So we have our website which is pushing the orders or when you
2:07:06
which is pushing the orders or when you
2:07:06
which is pushing the orders or when you hit that place order button goes into a
2:07:09
hit that place order button goes into a
2:07:09
hit that place order button goes into a big service called the order processing
2:07:10
big service called the order processing
2:07:10
big service called the order processing service. The order processing service
2:07:13
service. The order processing service
2:07:13
service. The order processing service then might reach out to the sales
2:07:15
then might reach out to the sales
2:07:15
then might reach out to the sales service and say hey create this order
2:07:17
service and say hey create this order
2:07:17
service and say hey create this order for me and the sales comes back uh with
2:07:20
for me and the sales comes back uh with
2:07:20
for me and the sales comes back uh with a response. Then the order processing
2:07:22
a response. Then the order processing
2:07:22
a response. Then the order processing goes and talks to the order payments.
2:07:25
goes and talks to the order payments.
2:07:25
goes and talks to the order payments. Sorry the payments is hidden here. The
2:07:27
Sorry the payments is hidden here. The
2:07:27
Sorry the payments is hidden here. The payments and says hey build this for me.
2:07:29
payments and says hey build this for me.
2:07:29
payments and says hey build this for me. And then somehow it gives a response
2:07:32
And then somehow it gives a response
2:07:32
And then somehow it gives a response magically and then say then it goes and
2:07:35
magically and then say then it goes and
2:07:35
magically and then say then it goes and talks to the customer status service to
2:07:38
talks to the customer status service to
2:07:38
talks to the customer status service to update the loyalty points and then it
2:07:40
update the loyalty points and then it
2:07:40
update the loyalty points and then it might then give it uh give the response
2:07:43
might then give it uh give the response
2:07:43
might then give it uh give the response back to the order processing and then
2:07:45
back to the order processing and then
2:07:45
back to the order processing and then the response goes back all the way back
2:07:47
the response goes back all the way back
2:07:47
the response goes back all the way back to the client. That is when the client
2:07:50
to the client. That is when the client
2:07:50
to the client. That is when the client uh gets to know yeah the order has gone
2:07:52
uh gets to know yeah the order has gone
2:07:52
uh gets to know yeah the order has gone through. Now what you might have compare
2:07:57
through. Now what you might have compare
2:07:57
through. Now what you might have compare this with the policies that we just
2:07:59
this with the policies that we just
2:07:59
this with the policies that we just spoke about what if one of the services
2:08:01
spoke about what if one of the services
2:08:01
spoke about what if one of the services is down what if the network is congested
2:08:04
is down what if the network is congested
2:08:04
is down what if the network is congested and the data doesn't reach on time there
2:08:06
and the data doesn't reach on time there
2:08:06
and the data doesn't reach on time there could be that chance of HTB timeout
2:08:08
could be that chance of HTB timeout
2:08:08
could be that chance of HTB timeout exception right what if one of the
2:08:10
exception right what if one of the
2:08:10
exception right what if one of the services has been updated by a team and
2:08:12
services has been updated by a team and
2:08:12
services has been updated by a team and the others other other services just
2:08:15
the others other other services just
2:08:15
the others other other services just cannot cope up there's the risk of that
2:08:18
cannot cope up there's the risk of that
2:08:18
cannot cope up there's the risk of that too so what we have is a scenario of
2:08:20
too so what we have is a scenario of
2:08:20
too so what we have is a scenario of very tight coupling each service like If
2:08:23
very tight coupling each service like If
2:08:23
very tight coupling each service like If you look at the order processing
2:08:24
you look at the order processing
2:08:24
you look at the order processing service, it needs to know that it needs
2:08:26
service, it needs to know that it needs
2:08:26
service, it needs to know that it needs to call the sales, it needs to call the
2:08:28
to call the sales, it needs to call the
2:08:28
to call the sales, it needs to call the order, it needs to call the uh order
2:08:30
order, it needs to call the uh order
2:08:30
order, it needs to call the uh order payment and it needs to call the custom
2:08:31
payment and it needs to call the custom
2:08:31
payment and it needs to call the custom status. Why? Why can't just the order
2:08:34
status. Why? Why can't just the order
2:08:34
status. Why? Why can't just the order processing handoff and then just move on
2:08:36
processing handoff and then just move on
2:08:36
processing handoff and then just move on to do other things? That is what you
2:08:38
to do other things? That is what you
2:08:38
to do other things? That is what you want to do right here. There's too many
2:08:40
want to do right here. There's too many
2:08:40
want to do right here. There's too many responsibilities on any service that is
2:08:43
responsibilities on any service that is
2:08:43
responsibilities on any service that is doing it. And you might think at this
2:08:45
doing it. And you might think at this
2:08:45
doing it. And you might think at this point that you can bring in poly to keep
2:08:48
point that you can bring in poly to keep
2:08:48
point that you can bring in poly to keep doing the retries if there's failures
2:08:50
doing the retries if there's failures
2:08:50
doing the retries if there's failures happening. But that's not enough because
2:08:53
happening. But that's not enough because
2:08:53
happening. But that's not enough because what about the data and the item potency
2:08:56
what about the data and the item potency
2:08:56
what about the data and the item potency around it? Do you want to take the
2:08:57
around it? Do you want to take the
2:08:57
around it? Do you want to take the payment twice? No. The underlying
2:09:00
payment twice? No. The underlying
2:09:00
payment twice? No. The underlying problem here is what's known as temporal
2:09:02
problem here is what's known as temporal
2:09:02
problem here is what's known as temporal coupling. This is the tight coupling
2:09:03
coupling. This is the tight coupling
2:09:03
coupling. This is the tight coupling that I've been talking about. The idea
2:09:06
that I've been talking about. The idea
2:09:06
that I've been talking about. The idea that for two services to communicate to
2:09:09
that for two services to communicate to
2:09:09
that for two services to communicate to each other, they should be up and
2:09:10
each other, they should be up and
2:09:10
each other, they should be up and running at the same time. So if there's
2:09:13
running at the same time. So if there's
2:09:13
running at the same time. So if there's a sales service and the order processing
2:09:15
a sales service and the order processing
2:09:15
a sales service and the order processing both needs to be up and running I need
2:09:17
both needs to be up and running I need
2:09:17
both needs to be up and running I need to get the response back after talking
2:09:19
to get the response back after talking
2:09:19
to get the response back after talking to B directly uh and only then can I
2:09:22
to B directly uh and only then can I
2:09:22
to B directly uh and only then can I move on. So if B
2:09:24
move on. So if B
2:09:24
move on. So if B crashes there is no request there is no
2:09:27
crashes there is no request there is no
2:09:27
crashes there is no request there is no response right and at that point A is
2:09:30
response right and at that point A is
2:09:30
response right and at that point A is completely blocked A cannot do anything
2:09:32
completely blocked A cannot do anything
2:09:32
completely blocked A cannot do anything and there's failure on the face of the
2:09:34
and there's failure on the face of the
2:09:34
and there's failure on the face of the user and while that request has been
2:09:37
user and while that request has been
2:09:37
user and while that request has been sent to B is still waiting doing
2:09:40
sent to B is still waiting doing
2:09:40
sent to B is still waiting doing nothing. Yeah, that is money lost
2:09:43
nothing. Yeah, that is money lost
2:09:43
nothing. Yeah, that is money lost probably during that time in compute
2:09:46
probably during that time in compute
2:09:46
probably during that time in compute power. There's also the request response
2:09:48
power. There's also the request response
2:09:48
power. There's also the request response pattern that we see here. I am not
2:09:50
pattern that we see here. I am not
2:09:50
pattern that we see here. I am not saying that this is a problem. But when
2:09:52
saying that this is a problem. But when
2:09:52
saying that this is a problem. But when it comes to high throughput, high
2:09:54
it comes to high throughput, high
2:09:54
it comes to high throughput, high performant scenarios, we cannot rely on
2:09:57
performant scenarios, we cannot rely on
2:09:57
performant scenarios, we cannot rely on request response because it follows the
2:09:59
request response because it follows the
2:09:59
request response because it follows the synchronous processing technique because
2:10:02
synchronous processing technique because
2:10:02
synchronous processing technique because HTTP by nature is synchronous. We cannot
2:10:05
HTTP by nature is synchronous. We cannot
2:10:05
HTTP by nature is synchronous. We cannot have async processing with request
2:10:07
have async processing with request
2:10:07
have async processing with request response. So this is also that something
2:10:09
response. So this is also that something
2:10:09
response. So this is also that something cannot really fit into this high
2:10:11
cannot really fit into this high
2:10:11
cannot really fit into this high throughput high performance scenario
2:10:13
throughput high performance scenario
2:10:13
throughput high performance scenario mission critical systems. So what we
2:10:16
mission critical systems. So what we
2:10:16
mission critical systems. So what we have built here is a house of cards and
2:10:19
have built here is a house of cards and
2:10:19
have built here is a house of cards and not just a house of cards but one that
2:10:22
not just a house of cards but one that
2:10:22
not just a house of cards but one that is sitting on top of Asian waves. Now
2:10:24
is sitting on top of Asian waves. Now
2:10:24
is sitting on top of Asian waves. Now this is not about bashing HTTP APIs or
2:10:27
this is not about bashing HTTP APIs or
2:10:28
this is not about bashing HTTP APIs or gRPC, GraphQL whatever because they are
2:10:30
gRPC, GraphQL whatever because they are
2:10:30
gRPC, GraphQL whatever because they are all battle tested. They are there for a
2:10:32
all battle tested. They are there for a
2:10:32
all battle tested. They are there for a purpose. What I'm talking about is
2:10:34
purpose. What I'm talking about is
2:10:34

2:10:52
better foundations by introducing what is known as a message cue so in reality
2:10:55

is known as a message cue so in reality it is not as simple as this there's a
2:10:57
it is not as simple as this there's a
2:10:57
it is not as simple as this there's a lot of thinking about the problem and
2:11:00
lot of thinking about the problem and
2:11:00
lot of thinking about the problem and the solution before you go into
2:11:01
the solution before you go into
2:11:01
the solution before you go into implementing this But to have an
2:11:04
implementing this But to have an
2:11:04
implementing this But to have an introduction to messaging today, let us
2:11:06
introduction to messaging today, let us
2:11:06
introduction to messaging today, let us just assume that we have introduced a
2:11:08
just assume that we have introduced a
2:11:08
just assume that we have introduced a message queue in between. What is a
2:11:10
message queue in between. What is a
2:11:10
message queue in between. What is a message Q? Consider it like a database
2:11:13
message Q? Consider it like a database
2:11:13
message Q? Consider it like a database uh but instead of rows you have little
2:11:15
uh but instead of rows you have little
2:11:15
uh but instead of rows you have little messages. And what are messages? They
2:11:17
messages. And what are messages? They
2:11:17
messages. And what are messages? They are basically what you would have in
2:11:19
are basically what you would have in
2:11:19
are basically what you would have in your request information. So with the
2:11:22
your request information. So with the
2:11:22
your request information. So with the message Q in place, A will actually send
2:11:25
message Q in place, A will actually send
2:11:25
message Q in place, A will actually send a message into the message Q and at that
2:11:28
a message into the message Q and at that
2:11:28
a message into the message Q and at that point the message gets stored into the
2:11:30
point the message gets stored into the
2:11:30
point the message gets stored into the message Q. A is not blocked at all. A
2:11:33
message Q. A is not blocked at all. A
2:11:33
message Q. A is not blocked at all. A can continue doing whatever else it
2:11:35
can continue doing whatever else it
2:11:35
can continue doing whatever else it needs to do. And B is the on the other
2:11:38
needs to do. And B is the on the other
2:11:38
needs to do. And B is the on the other side of the message queue. B might be
2:11:40
side of the message queue. B might be
2:11:40
side of the message queue. B might be crashed at that point. B might be
2:11:42
crashed at that point. B might be
2:11:42
crashed at that point. B might be undergoing an update or B might be
2:11:44
undergoing an update or B might be
2:11:44
undergoing an update or B might be online. But whenever B is ready to
2:11:47
online. But whenever B is ready to
2:11:47
online. But whenever B is ready to process things further, it takes the
2:11:49
process things further, it takes the
2:11:49
process things further, it takes the message from the message Q, processes it
2:11:52
message from the message Q, processes it
2:11:52
message from the message Q, processes it and deletes it. So in a single shot, we
2:11:55
and deletes it. So in a single shot, we
2:11:55
and deletes it. So in a single shot, we have gotten rid of the temporal coupling
2:11:57
have gotten rid of the temporal coupling
2:11:57
have gotten rid of the temporal coupling and note that there is no request
2:11:59
and note that there is no request
2:11:59
and note that there is no request response. Why? because message cues or
2:12:01
response. Why? because message cues or
2:12:01
response. Why? because message cues or message brokers they rely on protocols
2:12:04
message brokers they rely on protocols
2:12:04
message brokers they rely on protocols like AMQP which by nature is
2:12:07
like AMQP which by nature is
2:12:07
like AMQP which by nature is asynchronous
2:12:08
asynchronous
2:12:08
asynchronous processing. So where do we start with
2:12:11
processing. So where do we start with

it But when you think about real high throughput scenarios, using database as
2:13:58
throughput scenarios, using database as
2:13:58
throughput scenarios, using database as a queue is probably not a good idea
2:13:59
a queue is probably not a good idea
2:14:00
a queue is probably not a good idea because it's also adding load to your
2:14:01
because it's also adding load to your

because it's also adding load to your own database service. Now we have our
2:14:04
own database service. Now we have our
2:14:04
own database service. Now we have our messaging queue in place. Suppose say
2:14:07
messaging queue in place. Suppose say

sounds fun. Let me actually build a car. You know trust me there are people who
2:16:11
You know trust me there are people who
2:16:11
You know trust me there are people who build a car but then you have to think
2:16:13
build a car but then you have to think
2:16:13
build a car but then you have to think about the roadworthiness of it. You have
2:16:15
about the roadworthiness of it. You have
2:16:15
about the roadworthiness of it. You have to consider the paperwork that goes
2:16:17
to consider the paperwork that goes
2:16:17
to consider the paperwork that goes behind it. Do you really want to be
2:16:19
behind it. Do you really want to be

behind it. Do you really want to be doing it? Of course there is the
2:16:20
doing it? Of course there is the
2:16:20
doing it? Of course there is the learning but then one of the key
2:16:22
learning but then one of the key
2:16:22
learning but then one of the key learnings at the end of it would be I
2:16:25
learnings at the end of it would be I
2:16:25
learnings at the end of it would be I don't want to do it ever again. I don't

want to be servicing this car. It is going to sit as a car which is not going
2:16:30
going to sit as a car which is not going

going to sit as a car which is not going to be used on my driveway. I built that
2:16:33
to be used on my driveway. I built that
2:16:33
to be used on my driveway. I built that car. That is it. I don't want to be
2:16:34
car. That is it. I don't want to be
2:16:34
car. That is it. I don't want to be servicing it. So my point being do not
2:16:37
servicing it. So my point being do not
2:16:37
servicing it. So my point being do not reinvent the wheel. use one of these
2:16:39
reinvent the wheel. use one of these
2:16:39
reinvent the wheel. use one of these libraries and service bus, mass transit,

libraries and service bus, mass transit, writer, rebus, wolverine, all of these
2:16:44
writer, rebus, wolverine, all of these
2:16:44
writer, rebus, wolverine, all of these are messaging libraries. They all come
2:16:46
are messaging libraries. They all come
2:16:46
are messaging libraries. They all come with patterns that I just spoke about
2:16:49
with patterns that I just spoke about

with patterns that I just spoke about that has been built in. You can make use
2:16:51
that has been built in. You can make use
2:16:51
that has been built in. You can make use of those amenities yourself. So this
2:16:54
of those amenities yourself. So this
2:16:54
of those amenities yourself. So this helps you focus on the business code. In
2:16:56
helps you focus on the business code. In
2:16:56
helps you focus on the business code. In today's example, I'm going to be using N
2:16:58
today's example, I'm going to be using N
2:16:58
today's example, I'm going to be using N service plus because that is what I am
2:17:00
service plus because that is what I am
2:17:00
service plus because that is what I am used to. But regardless of that, feel
2:17:03
used to. But regardless of that, feel
2:17:04
used to. But regardless of that, feel free to use any of this because all the
2:17:06
free to use any of this because all the
2:17:06
free to use any of this because all the code that I show you, it is just the
2:17:07
code that I show you, it is just the
2:17:07
code that I show you, it is just the APIs that keep changing. The patterns
2:17:10
APIs that keep changing. The patterns
2:17:10
APIs that keep changing. The patterns are the same regardless of the library
2:17:12
are the same regardless of the library
2:17:12
are the same regardless of the library you use. So just putting it out there,
2:17:15
you use. So just putting it out there,
2:17:15
you use. So just putting it out there, do not reinvent the wheel because what
2:17:17
do not reinvent the wheel because what
2:17:17
do not reinvent the wheel because what you might end up writing is a cheaper
2:17:19
you might end up writing is a cheaper
2:17:19
you might end up writing is a cheaper version of one of these libraries that
2:17:22
version of one of these libraries that
2:17:22
version of one of these libraries that is going to cost you a fortune in the
2:17:25
is going to cost you a fortune in the
2:17:25
is going to cost you a fortune in the long run servicing and maintaining it.
2:17:27
long run servicing and maintaining it.
2:17:27
long run servicing and maintaining it. Save yourself from the headache because
2:17:28
Save yourself from the headache because
2:17:28
Save yourself from the headache because a distributed system is no mean feat. So
2:17:32
a distributed system is no mean feat. So
2:17:32
a distributed system is no mean feat. So time for some code now. So what we will
2:17:34
time for some code now. So what we will
2:17:34
time for some code now. So what we will discuss are these main points,
2:17:36
discuss are these main points,
2:17:36
discuss are these main points, endpoints, commands and pointto-point
2:17:37
endpoints, commands and pointto-point
2:17:38
endpoints, commands and pointto-point communication, events, publish and
2:17:39
communication, events, publish and
2:17:40
communication, events, publish and subscribe. We will see if we can extend
2:17:42
subscribe. We will see if we can extend
2:17:42
subscribe. We will see if we can extend our system if time permits and we'll
2:17:44
our system if time permits and we'll
2:17:44
our system if time permits and we'll also talk about recoverabilities and
2:17:47
also talk about recoverabilities and
2:17:47
also talk about recoverabilities and retries. So let's go to Ryder.
2:17:52
retries. So let's go to Ryder.
2:17:52
retries. So let's go to Ryder. What I have here is a solution with four
2:17:56
What I have here is a solution with four
2:17:56
What I have here is a solution with four projects. I have unloaded something. Let
2:17:58
projects. I have unloaded something. Let
2:17:58
projects. I have unloaded something. Let us bring that into picture when the time
2:18:00
us bring that into picture when the time
2:18:00
us bring that into picture when the time is ready. So the client UI is basically
2:18:03
is ready. So the client UI is basically
2:18:03
is ready. So the client UI is basically the website which is the web front end
2:18:05
the website which is the web front end
2:18:05
the website which is the web front end ASP.NET Core NBC application. Nothing
2:18:08
ASP.NET Core NBC application. Nothing
2:18:08
ASP.NET Core NBC application. Nothing too fancy about it. And I've got two
2:18:11
too fancy about it. And I've got two
2:18:11
too fancy about it. And I've got two services which is the sales endpoint and
2:18:13
services which is the sales endpoint and
2:18:13
services which is the sales endpoint and the billing endpoint. So in reality I
2:18:16
the billing endpoint. So in reality I
2:18:16
the billing endpoint. So in reality I might be hosting these as Windows
2:18:18
might be hosting these as Windows
2:18:18
might be hosting these as Windows services. the billing and the sales end
2:18:20
services. the billing and the sales end
2:18:20
services. the billing and the sales end points as Windows services or even as
2:18:22
points as Windows services or even as
2:18:22
points as Windows services or even as like an Azure web job. The client UI
2:18:24
like an Azure web job. The client UI
2:18:24
like an Azure web job. The client UI that is a website that could be hosted
2:18:26
that is a website that could be hosted
2:18:26
that is a website that could be hosted anywhere or even on Azure. So as I said
2:18:29
anywhere or even on Azure. So as I said
2:18:29
anywhere or even on Azure. So as I said I'm using N service bus because that is
2:18:31
I'm using N service bus because that is
2:18:31
I'm using N service bus because that is what I'm familiar with but feel free to
2:18:33
what I'm familiar with but feel free to
2:18:33
what I'm familiar with but feel free to use Transit or Wolverine or Rebus
2:18:36
use Transit or Wolverine or Rebus
2:18:36
use Transit or Wolverine or Rebus because the patterns just keep
2:18:37
because the patterns just keep
2:18:37
because the patterns just keep repeating. It's just the semantics and
2:18:39
repeating. It's just the semantics and
2:18:40
repeating. It's just the semantics and the APIs, the names of the APIs and the
2:18:41
the APIs, the names of the APIs and the
2:18:42
the APIs, the names of the APIs and the methods that keep changing. So in my
2:18:44
methods that keep changing. So in my
2:18:44
methods that keep changing. So in my controllers I have the home controller.
2:18:47
controllers I have the home controller.
2:18:47
controllers I have the home controller. there's a place order button. So if I
2:18:49
there's a place order button. So if I
2:18:49
there's a place order button. So if I just run this demo and show you what the
2:18:52
just run this demo and show you what the
2:18:52
just run this demo and show you what the web front end looks like, it is very
2:18:54
web front end looks like, it is very
2:18:54
web front end looks like, it is very simple and basic uh for this 35 minute
2:18:57
simple and basic uh for this 35 minute
2:18:57
simple and basic uh for this 35 minute session again. So I have this big button
2:19:00
session again. So I have this big button
2:19:00
session again. So I have this big button which places an order and it tells me
2:19:02
which places an order and it tells me
2:19:02
which places an order and it tells me that a order has been placed. So when
2:19:06
that a order has been placed. So when
2:19:06
that a order has been placed. So when that place order button is clicked, what
2:19:08
that place order button is clicked, what
2:19:08
that place order button is clicked, what happens is it goes and invokes this
2:19:11
happens is it goes and invokes this
2:19:11
happens is it goes and invokes this action method for me. So in in here I
2:19:14
action method for me. So in in here I
2:19:14
action method for me. So in in here I create a new order id and then I
2:19:17
create a new order id and then I
2:19:17
create a new order id and then I instantiate something of the type place
2:19:19
instantiate something of the type place
2:19:19
instantiate something of the type place order and I am sending that object that
2:19:22
order and I am sending that object that
2:19:22
order and I am sending that object that I've just created using something called
2:19:24
I've just created using something called
2:19:24
I've just created using something called message session. So what is actually
2:19:26
message session. So what is actually
2:19:26
message session. So what is actually happening? So message session is like an
2:19:28
happening? So message session is like an
2:19:28
happening? So message session is like an interface in n service bus that helps me
2:19:30
interface in n service bus that helps me
2:19:30
interface in n service bus that helps me do basic operations on the message like
2:19:32
do basic operations on the message like
2:19:32
do basic operations on the message like sending a message or publishing or
2:19:34
sending a message or publishing or
2:19:34
sending a message or publishing or receiving a message. Um and I am using
2:19:37
receiving a message. Um and I am using
2:19:37
receiving a message. Um and I am using that to send something. Now what is that
2:19:40
that to send something. Now what is that
2:19:40
that to send something. Now what is that something that I'm sending? So if we
2:19:42
something that I'm sending? So if we
2:19:42
something that I'm sending? So if we look at the place order class, it's a
2:19:45
look at the place order class, it's a
2:19:45
look at the place order class, it's a plain old CLR object which inherits from
2:19:48
plain old CLR object which inherits from
2:19:48
plain old CLR object which inherits from I command and this is what I'm sending.
2:19:51
I command and this is what I'm sending.
2:19:51
I command and this is what I'm sending. In reality, it'll be your entire request
2:19:54
In reality, it'll be your entire request
2:19:54
In reality, it'll be your entire request which contains all the details of the
2:19:56
which contains all the details of the
2:19:56
which contains all the details of the products and everything. That's one way
2:19:58
products and everything. That's one way
2:19:58
products and everything. That's one way of doing it. But inheriting from I
2:20:00
of doing it. But inheriting from I
2:20:00
of doing it. But inheriting from I command is telling the system that is
2:20:03
command is telling the system that is
2:20:03
command is telling the system that is it's telling an N service bus that hey
2:20:05
it's telling an N service bus that hey
2:20:05
it's telling an N service bus that hey this is a message. This needs needs to
2:20:07
this is a message. This needs needs to
2:20:07
this is a message. This needs needs to be treated like a command. Now in comes
2:20:10
be treated like a command. Now in comes
2:20:10
be treated like a command. Now in comes the concept of the two different types
2:20:12
the concept of the two different types
2:20:12
the concept of the two different types of message here. This is a command. A
2:20:15
of message here. This is a command. A
2:20:15
of message here. This is a command. A command is an instruction. So it is a
2:20:17
command is an instruction. So it is a
2:20:17
command is an instruction. So it is a very valuable method and me as a sender
2:20:20
very valuable method and me as a sender
2:20:20
very valuable method and me as a sender I expect someone to take action upon it.
2:20:24
I expect someone to take action upon it.
2:20:24
I expect someone to take action upon it. So if I expect someone to take action
2:20:26
So if I expect someone to take action
2:20:26
So if I expect someone to take action upon it and it is a high value thing I
2:20:28
upon it and it is a high value thing I
2:20:28
upon it and it is a high value thing I need to make sure that I know at least
2:20:31
need to make sure that I know at least
2:20:31
need to make sure that I know at least who is going to deal with it. So that
2:20:34
who is going to deal with it. So that
2:20:34
who is going to deal with it. So that also can be configured but as a sender I
2:20:37
also can be configured but as a sender I
2:20:37
also can be configured but as a sender I don't need to know whether that that
2:20:40
don't need to know whether that that
2:20:40
don't need to know whether that that receiving party or whoever is going to
2:20:41
receiving party or whoever is going to
2:20:42
receiving party or whoever is going to deal with my instruction is up and
2:20:43
deal with my instruction is up and
2:20:43
deal with my instruction is up and running or down or whatever. I just need
2:20:46
running or down or whatever. I just need
2:20:46
running or down or whatever. I just need to know that there is this someone who I
2:20:48
to know that there is this someone who I
2:20:48
to know that there is this someone who I need to send the instruction to who is
2:20:50
need to send the instruction to who is
2:20:50
need to send the instruction to who is going to do the work for me at some
2:20:52
going to do the work for me at some
2:20:52
going to do the work for me at some point. So using the message session I'm
2:20:55
point. So using the message session I'm
2:20:55
point. So using the message session I'm sending that command and how that
2:20:57
sending that command and how that
2:20:57
sending that command and how that sending is controlled in a centralized
2:21:00
sending is controlled in a centralized
2:21:00
sending is controlled in a centralized manner is from the program. uh CS. So
2:21:03
manner is from the program. uh CS. So
2:21:03
manner is from the program. uh CS. So here I have this API called route to
2:21:05
here I have this API called route to
2:21:05
here I have this API called route to endpoint where I say the type of place
2:21:08
endpoint where I say the type of place
2:21:08
endpoint where I say the type of place order classes or the objects of type
2:21:10
order classes or the objects of type
2:21:10
order classes or the objects of type place order the destination would be the
2:21:13
place order the destination would be the
2:21:13
place order the destination would be the sales for it the sales endpoint or the
2:21:15
sales for it the sales endpoint or the
2:21:15
sales for it the sales endpoint or the sales Q. So as you can see there is a
2:21:17
sales Q. So as you can see there is a
2:21:17
sales Q. So as you can see there is a website and it is talking directly just
2:21:20
website and it is talking directly just
2:21:20
website and it is talking directly just to the queue not the sales service it's
2:21:22
to the queue not the sales service it's
2:21:22
to the queue not the sales service it's the sales queue that it is talking to.
2:21:24
the sales queue that it is talking to.
2:21:24
the sales queue that it is talking to. So it centralizes all the connection for
2:21:27
So it centralizes all the connection for
2:21:27
So it centralizes all the connection for me. Um, and this is now also an endpoint
2:21:31
me. Um, and this is now also an endpoint
2:21:31
me. Um, and this is now also an endpoint because that is how we treat things in
2:21:33
because that is how we treat things in
2:21:33
because that is how we treat things in in service bus. An endpoint means it's a
2:21:35
in service bus. An endpoint means it's a
2:21:35
in service bus. An endpoint means it's a service that can send or receive
2:21:37
service that can send or receive
2:21:37
service that can send or receive messages. Um, and of course there is the
2:21:41
messages. Um, and of course there is the
2:21:41
messages. Um, and of course there is the the the uh configuration for the SQL
2:21:43
the the uh configuration for the SQL
2:21:43
the the uh configuration for the SQL transport which I'm using today and um a
2:21:46
transport which I'm using today and um a
2:21:46
transport which I'm using today and um a little bit of N service endpoint
2:21:48
little bit of N service endpoint
2:21:48
little bit of N service endpoint configuration. So that is the client UI
2:21:50
configuration. So that is the client UI
2:21:50
configuration. So that is the client UI which sends the message or sends the
2:21:53
which sends the message or sends the
2:21:53
which sends the message or sends the command. Now let us go and visit the
2:21:56
command. Now let us go and visit the
2:21:56
command. Now let us go and visit the sales service. So the sales service is
2:21:58
sales service. So the sales service is
2:21:58
sales service. So the sales service is where the place order instruction is
2:22:00
where the place order instruction is
2:22:00
where the place order instruction is received. So it needs to process that
2:22:03
received. So it needs to process that
2:22:03
received. So it needs to process that command and for that there is a class
2:22:05
command and for that there is a class
2:22:05
command and for that there is a class which uh which says that hey I am here
2:22:08
which uh which says that hey I am here
2:22:08
which uh which says that hey I am here to catch all the commands that you send
2:22:10
to catch all the commands that you send
2:22:10
to catch all the commands that you send of the type placeholder. Let me deal
2:22:12
of the type placeholder. Let me deal
2:22:12
of the type placeholder. Let me deal with it. So in the placeholder
2:22:15
with it. So in the placeholder
2:22:15
with it. So in the placeholder handler we have a class that inherits
2:22:18
handler we have a class that inherits
2:22:18
handler we have a class that inherits from I handle message messages of type
2:22:21
from I handle message messages of type
2:22:21
from I handle message messages of type T. So marking a class inheriting from I
2:22:24
T. So marking a class inheriting from I
2:22:24
T. So marking a class inheriting from I handle messages of the type placeholder
2:22:27
handle messages of the type placeholder
2:22:27
handle messages of the type placeholder say say is shouting out love to the
2:22:29
say say is shouting out love to the
2:22:29
say say is shouting out love to the system that I am here to handle all the
2:22:32
system that I am here to handle all the
2:22:32
system that I am here to handle all the commands or or all the messages of the
2:22:34
commands or or all the messages of the
2:22:34
commands or or all the messages of the type place order and inside my handler
2:22:39
type place order and inside my handler
2:22:39
type place order and inside my handler there's a handle method where I can get
2:22:41
there's a handle method where I can get
2:22:41
there's a handle method where I can get the message as well as the context. So
2:22:44
the message as well as the context. So
2:22:44
the message as well as the context. So if you think about HTTP context the
2:22:47
if you think about HTTP context the
2:22:48
if you think about HTTP context the iMessage handler context is something
2:22:49
iMessage handler context is something
2:22:49
iMessage handler context is something like that. It gives me access to the the
2:22:52
like that. It gives me access to the the
2:22:52
like that. It gives me access to the the context because this is a service that
2:22:54
context because this is a service that
2:22:54
context because this is a service that has been invoked by a message. With HTTP
2:22:57
has been invoked by a message. With HTTP
2:22:57
has been invoked by a message. With HTTP APIs, you are invoking using HTTP
2:23:00
APIs, you are invoking using HTTP
2:23:00
APIs, you are invoking using HTTP request. Here it is invoked using a
2:23:02
request. Here it is invoked using a
2:23:02
request. Here it is invoked using a message. So in here I can then do some
2:23:06
message. So in here I can then do some
2:23:06
message. So in here I can then do some business logic that is processing the
2:23:08
business logic that is processing the
2:23:08
business logic that is processing the order or saving it to the database in
2:23:10
order or saving it to the database in
2:23:10
order or saving it to the database in this instance. And then we have some
2:23:13
this instance. And then we have some
2:23:13
this instance. And then we have some interesting things happening. If you see
2:23:15
interesting things happening. If you see
2:23:15
interesting things happening. If you see here there is another object called
2:23:17
here there is another object called
2:23:17
here there is another object called order placed being instantiated.
2:23:20
order placed being instantiated.
2:23:20
order placed being instantiated. And I'm using the context API, the
2:23:22
And I'm using the context API, the
2:23:22
And I'm using the context API, the publish API and the context to publish
2:23:25
publish API and the context to publish
2:23:25
publish API and the context to publish it. Here I'm not sending, I am
2:23:27
it. Here I'm not sending, I am
2:23:27
it. Here I'm not sending, I am publishing it. So what is the
2:23:28
publishing it. So what is the
2:23:28
publishing it. So what is the difference? So this is an event. Event
2:23:31
difference? So this is an event. Event
2:23:31
difference? So this is an event. Event is like letting uh letting the world
2:23:33
is like letting uh letting the world
2:23:33
is like letting uh letting the world know that something has happened. While
2:23:35
know that something has happened. While
2:23:35
know that something has happened. While command is an instruction that says do
2:23:38
command is an instruction that says do
2:23:38
command is an instruction that says do this. Event is like something happened.
2:23:41
this. Event is like something happened.
2:23:41
this. Event is like something happened. I have done it. So the sales endpoint or
2:23:44
I have done it. So the sales endpoint or
2:23:44
I have done it. So the sales endpoint or the sales service is saying that yep I
2:23:46
the sales service is saying that yep I
2:23:46
the sales service is saying that yep I have saved the order to the database. my
2:23:49
have saved the order to the database. my
2:23:49
have saved the order to the database. my job is done. I am just letting others
2:23:51
job is done. I am just letting others
2:23:51
job is done. I am just letting others know that I have done my job so that
2:23:53
know that I have done my job so that
2:23:53
know that I have done my job so that others can pick up on what is left to
2:23:55
others can pick up on what is left to
2:23:55
others can pick up on what is left to do. So as you can see here there's just
2:23:57
do. So as you can see here there's just
2:23:58
do. So as you can see here there's just one responsibility residing on the sales
2:24:00
one responsibility residing on the sales
2:24:00
one responsibility residing on the sales service which is creating that order in
2:24:03
service which is creating that order in
2:24:03
service which is creating that order in the database. So another thing to note
2:24:06
the database. So another thing to note
2:24:06
the database. So another thing to note here is that the order placed event is
2:24:09
here is that the order placed event is
2:24:09
here is that the order placed event is again very lightweight. In reality it
2:24:11
again very lightweight. In reality it
2:24:11
again very lightweight. In reality it might be different but the order placed
2:24:14
might be different but the order placed
2:24:14
might be different but the order placed inherits from I event which lets the
2:24:16
inherits from I event which lets the
2:24:16
inherits from I event which lets the system know that this is an event. Now
2:24:17
system know that this is an event. Now
2:24:17
system know that this is an event. Now if you look at the semantics of a
2:24:19
if you look at the semantics of a
2:24:19
if you look at the semantics of a command and event the event semantic is
2:24:23
command and event the event semantic is
2:24:23
command and event the event semantic is a noun plus a verb in past tense and for
2:24:26
a noun plus a verb in past tense and for
2:24:26
a noun plus a verb in past tense and for command is like a verb in present tense
2:24:30
command is like a verb in present tense
2:24:30
command is like a verb in present tense plus a noun. So so that this way you can
2:24:33
plus a noun. So so that this way you can
2:24:33
plus a noun. So so that this way you can easily make out which is a command which
2:24:35
easily make out which is a command which
2:24:35
easily make out which is a command which is an event without even going to the uh
2:24:37
is an event without even going to the uh
2:24:37
is an event without even going to the uh without even going inside the class and
2:24:39
without even going inside the class and
2:24:39
without even going inside the class and speaking into the class. So so something
2:24:41
speaking into the class. So so something
2:24:41
speaking into the class. So so something like a best practice. So now we have
2:24:43
like a best practice. So now we have
2:24:43
like a best practice. So now we have published the event and if you look at
2:24:45
published the event and if you look at
2:24:45
published the event and if you look at program.cs is I'm not talking to anyone
2:24:48
program.cs is I'm not talking to anyone
2:24:48
program.cs is I'm not talking to anyone right because that is because this is an
2:24:50
right because that is because this is an
2:24:50
right because that is because this is an event I just need to let the world know
2:24:53
event I just need to let the world know
2:24:53
event I just need to let the world know whether someone will listen to me how
2:24:55
whether someone will listen to me how
2:24:55
whether someone will listen to me how many listeners will be there I don't
2:24:58
many listeners will be there I don't
2:24:58
many listeners will be there I don't care I just need to let the world know
2:24:59
care I just need to let the world know
2:25:00
care I just need to let the world know it is like me talking to you it's like a
2:25:01
it is like me talking to you it's like a
2:25:01
it is like me talking to you it's like a broadcast there could be one or many
2:25:04
broadcast there could be one or many
2:25:04
broadcast there could be one or many listeners and those listeners are called
2:25:06
listeners and those listeners are called
2:25:06
listeners and those listeners are called subscribers and this is the basic of
2:25:09
subscribers and this is the basic of
2:25:09
subscribers and this is the basic of event-driven architecture what we are
2:25:10
event-driven architecture what we are
2:25:10
event-driven architecture what we are doing as a pattern is publish subscribe
2:25:12
doing as a pattern is publish subscribe
2:25:12
doing as a pattern is publish subscribe and this is the basics of the
2:25:13
and this is the basics of the
2:25:13
and this is the basics of the event-driven architecture And the beauty
2:25:16
event-driven architecture And the beauty
2:25:16
event-driven architecture And the beauty with event- driven architecture that is
2:25:17
with event- driven architecture that is
2:25:17
with event- driven architecture that is that we get the space to extend the
2:25:20
that we get the space to extend the
2:25:20
that we get the space to extend the system easily because we can bring in
2:25:22
system easily because we can bring in
2:25:22
system easily because we can bring in more subscribers without affecting the
2:25:24
more subscribers without affecting the
2:25:24
more subscribers without affecting the system as a whole. Now how do we handle
2:25:27
system as a whole. Now how do we handle
2:25:27
system as a whole. Now how do we handle this order placed event that is getting
2:25:30
this order placed event that is getting
2:25:30
this order placed event that is getting done in the billing endpoint or the
2:25:32
done in the billing endpoint or the
2:25:32
done in the billing endpoint or the billing service. Here we have a handler
2:25:35
billing service. Here we have a handler
2:25:35
billing service. Here we have a handler again which inherits from I handle
2:25:36
again which inherits from I handle
2:25:36
again which inherits from I handle messages of type T which is order
2:25:39
messages of type T which is order
2:25:39
messages of type T which is order placed. In the handle method I can again
2:25:41
placed. In the handle method I can again
2:25:42
placed. In the handle method I can again do some business logic and then at the
2:25:44
do some business logic and then at the
2:25:44
do some business logic and then at the end I might send another command or
2:25:46
end I might send another command or
2:25:46
end I might send another command or publish another event that is also
2:25:47
publish another event that is also
2:25:48
publish another event that is also possible. Now let us see the demo in
2:25:50
possible. Now let us see the demo in
2:25:50
possible. Now let us see the demo in action. Yeah that's what does not ups.
2:25:56
action. Yeah that's what does not ups.
2:25:56
action. Yeah that's what does not ups. So let me bring up the for the run
2:25:59
So let me bring up the for the run
2:25:59
So let me bring up the for the run window. So I have the client UI here.
2:26:04
I'm going to place a few orders. Um just
2:26:07
I'm going to place a few orders. Um just
2:26:07
I'm going to place a few orders. Um just let us start with one to begin with that
2:26:09
let us start with one to begin with that
2:26:09
let us start with one to begin with that is CFB4 is the starting. If I look at
2:26:12
is CFB4 is the starting. If I look at
2:26:12
is CFB4 is the starting. If I look at the sales it has received the place or
2:26:15
the sales it has received the place or
2:26:15
the sales it has received the place or uh place order instruction. So if I look
2:26:17
uh place order instruction. So if I look
2:26:17
uh place order instruction. So if I look at the client UI to begin with I'm
2:26:19
at the client UI to begin with I'm
2:26:19
at the client UI to begin with I'm sending the command for the order ID
2:26:21
sending the command for the order ID
2:26:21
sending the command for the order ID CFD4. The sales receives it and then
2:26:24
CFD4. The sales receives it and then
2:26:24
CFD4. The sales receives it and then publishes the event for the order ID and
2:26:27
publishes the event for the order ID and
2:26:27
publishes the event for the order ID and in the billing I have now received the
2:26:31
in the billing I have now received the
2:26:31
in the billing I have now received the order placed and I can move on and do
2:26:33
order placed and I can move on and do
2:26:33
order placed and I can move on and do other things. Now we spoke about
2:26:35
other things. Now we spoke about
2:26:35
other things. Now we spoke about extending the system right. So I have
2:26:38
extending the system right. So I have
2:26:38
extending the system right. So I have another service that I have just hidden
2:26:40
another service that I have just hidden
2:26:40
another service that I have just hidden here. I'm going to load the project and
2:26:43
here. I'm going to load the project and
2:26:43
here. I'm going to load the project and then I am going to run this as well. So
2:26:45
then I am going to run this as well. So
2:26:45
then I am going to run this as well. So right now it is not running at all. I'm
2:26:48
right now it is not running at all. I'm
2:26:48
right now it is not running at all. I'm just going to run this again. This is a
2:26:51
just going to run this again. This is a
2:26:51
just going to run this again. This is a simple handler which handles the order
2:26:54
simple handler which handles the order
2:26:54
simple handler which handles the order placed.
2:26:56
placed.
2:26:56
placed. And if I run this
2:26:58
And if I run this
2:26:58
And if I run this now, that should also
2:27:07
run. Uh, give me a
2:27:11
run. Uh, give me a
2:27:11
run. Uh, give me a minute. I think this is up and running.
2:27:13
minute. I think this is up and running.
2:27:13
minute. I think this is up and running. Now, if I go and place a few other
2:27:15
Now, if I go and place a few other
2:27:15
Now, if I go and place a few other orders, I should see that the shipping
2:27:18
orders, I should see that the shipping
2:27:18
orders, I should see that the shipping or endpoint should receive some of the
2:27:20
or endpoint should receive some of the
2:27:20
or endpoint should receive some of the messages as well from the past. So we
2:27:23
messages as well from the past. So we
2:27:23
messages as well from the past. So we have extended our system without
2:27:25
have extended our system without
2:27:25
have extended our system without impacting the system as a whole. Now
2:27:27
impacting the system as a whole. Now
2:27:27
impacting the system as a whole. Now what if one of the endpoints is down? It
2:27:29
what if one of the endpoints is down? It
2:27:29
what if one of the endpoints is down? It has a bug. What happens behind the
2:27:32
has a bug. What happens behind the
2:27:32
has a bug. What happens behind the scenes? That is when the recoverability
2:27:34
scenes? That is when the recoverability
2:27:34
scenes? That is when the recoverability and the retries come in. So let us go
2:27:36
and the retries come in. So let us go
2:27:36
and the retries come in. So let us go and introduce a bug into our sales end
2:27:38
and introduce a bug into our sales end
2:27:38
and introduce a bug into our sales end point. But by just throwing an
2:27:40
point. But by just throwing an
2:27:40
point. But by just throwing an exception. So we just stop this and then
2:27:44
exception. So we just stop this and then
2:27:44
exception. So we just stop this and then run it all.
2:27:51
So the sales endpoint is completely
2:27:53
So the sales endpoint is completely
2:27:53
So the sales endpoint is completely failing at the moment because I have
2:27:55
failing at the moment because I have
2:27:55
failing at the moment because I have introduced a bug
2:27:57
introduced a bug
2:27:57
introduced a bug but that doesn't prevent the UI from
2:28:00
but that doesn't prevent the UI from
2:28:00
but that doesn't prevent the UI from working. I have placed a few orders now
2:28:04
working. I have placed a few orders now
2:28:04
working. I have placed a few orders now and the client UI must have sent a few
2:28:07
and the client UI must have sent a few
2:28:07
and the client UI must have sent a few messages. But when it comes to sales, it
2:28:10
messages. But when it comes to sales, it
2:28:10
messages. But when it comes to sales, it keeps on failing. So now what happens is
2:28:13
keeps on failing. So now what happens is
2:28:13
keeps on failing. So now what happens is in the sales I've got some
2:28:15
in the sales I've got some
2:28:15
in the sales I've got some recoverability in place. This is
2:28:17
recoverability in place. This is
2:28:17
recoverability in place. This is something that you would add to every
2:28:18
something that you would add to every
2:28:18
something that you would add to every endpoint. And with the recoverability,
2:28:20
endpoint. And with the recoverability,
2:28:20
endpoint. And with the recoverability, it says that hey when you have an error,
2:28:23
it says that hey when you have an error,
2:28:23
it says that hey when you have an error, retry it. And when the first retry
2:28:26
retry it. And when the first retry
2:28:26
retry it. And when the first retry fails, then back off exponentially 2
2:28:29
fails, then back off exponentially 2
2:28:29
fails, then back off exponentially 2 seconds, 4 seconds and so on till the
2:28:32
seconds, 4 seconds and so on till the
2:28:32
seconds, 4 seconds and so on till the point you cannot do it anymore. And then
2:28:35
point you cannot do it anymore. And then
2:28:35
point you cannot do it anymore. And then what you do is you don't sit and do
2:28:37
what you do is you don't sit and do
2:28:37
what you do is you don't sit and do anything. you move that message into
2:28:40
anything. you move that message into
2:28:40
anything. you move that message into into another queue called as the error
2:28:42
into another queue called as the error
2:28:42
into another queue called as the error queue and that is what is going on here.
2:28:45
queue and that is what is going on here.
2:28:45
queue and that is what is going on here. I think it retries for like three times
2:28:47
I think it retries for like three times
2:28:48
I think it retries for like three times before it completely backs off and moves
2:28:50
before it completely backs off and moves
2:28:50
before it completely backs off and moves the message into the queue. So if you
2:28:52
the message into the queue. So if you
2:28:52
the message into the queue. So if you look here there should be some messages
2:28:54
look here there should be some messages
2:28:54
look here there should be some messages in the monitoring area which I'm just
2:28:56
in the monitoring area which I'm just
2:28:56
in the monitoring area which I'm just going to show to you right now.
2:29:03
Let me bring that up here.
2:29:08
I should see a few failed messages. So
2:29:12
I should see a few failed messages. So
2:29:12
I should see a few failed messages. So if you look here, there is a message
2:29:14
if you look here, there is a message
2:29:14
if you look here, there is a message that has failed with the message
2:29:16
that has failed with the message
2:29:16
that has failed with the message body
2:29:17
body
2:29:17
body file. And that is indeed one of the
2:29:20
file. And that is indeed one of the
2:29:20
file. And that is indeed one of the messages that was sent by our
2:29:25
messages that was sent by our
2:29:25
messages that was sent by our client UI here. So at this point sales
2:29:27
client UI here. So at this point sales
2:29:27
client UI here. So at this point sales is failing but the client UI is up and
2:29:30
is failing but the client UI is up and
2:29:30
is failing but the client UI is up and running. So now let us simulate the
2:29:32
running. So now let us simulate the
2:29:32
running. So now let us simulate the scenario where we have gone and fixed
2:29:34
scenario where we have gone and fixed
2:29:34
scenario where we have gone and fixed the bug.
2:29:36
the bug.
2:29:36
the bug. Yeah. So here we are in the placeholder
2:29:38
Yeah. So here we are in the placeholder
2:29:38
Yeah. So here we are in the placeholder handler again. We have fixed the bug and
2:29:41
handler again. We have fixed the bug and
2:29:41
handler again. We have fixed the bug and we are running the app again.
2:29:44
we are running the app again.
2:29:44
we are running the app again. And now what I can do is when things are
2:29:46
And now what I can do is when things are
2:29:46
And now what I can do is when things are up and running I can go back to the
2:29:49
up and running I can go back to the
2:29:49
up and running I can go back to the monitoring area and then start uh
2:29:52
monitoring area and then start uh
2:29:52
monitoring area and then start uh retrying my messages the failed
2:29:54
retrying my messages the failed
2:29:54
retrying my messages the failed messages. So I can go into here
2:30:00
definitely not in the console in service
2:30:03
definitely not in the console in service
2:30:03
definitely not in the console in service and I can see failed messages. I I can
2:30:05
and I can see failed messages. I I can
2:30:05
and I can see failed messages. I I can go into one and I say retry this
2:30:07
go into one and I say retry this
2:30:07
go into one and I say retry this message. Yes, I want to retry this
2:30:09
message. Yes, I want to retry this
2:30:09
message. Yes, I want to retry this message. So it is getting retrieded. Now
2:30:11
message. So it is getting retrieded. Now
2:30:11
message. So it is getting retrieded. Now if I go into sales I should see that it
2:30:14
if I go into sales I should see that it
2:30:14
if I go into sales I should see that it is going to try and pick up the message
2:30:16
is going to try and pick up the message
2:30:16
is going to try and pick up the message that just failed.
2:30:18
that just failed.
2:30:18
that just failed. So let us see.
2:30:23
Come on. Yeah.
2:30:26
Come on. Yeah.
2:30:26
Come on. Yeah. Yeah. Yeah. Because we don't Yeah. You
2:30:29
Yeah. Yeah. Because we don't Yeah. You
2:30:29
Yeah. Yeah. Because we don't Yeah. You just retry. I can send you I can export
2:30:32
just retry. I can send you I can export
2:30:32
just retry. I can send you I can export this whatever they are. But I mean we
2:30:35
this whatever they are. But I mean we
2:30:35
this whatever they are. But I mean we don't get tickets for these. Yeah. I
2:30:36
don't get tickets for these. Yeah. I
2:30:36
don't get tickets for these. Yeah. I mean security is not bothered. There you
2:30:38
mean security is not bothered. There you
2:30:38
mean security is not bothered. There you go. So the message with the message
2:30:42
go. So the message with the message
2:30:42
go. So the message with the message body PFI CE that has been retrieded and
2:30:46
body PFI CE that has been retrieded and
2:30:46
body PFI CE that has been retrieded and the order has been the order placed
2:30:48
the order has been the order placed
2:30:48
the order has been the order placed event has been published and then the
2:30:50
event has been published and then the
2:30:50
event has been published and then the billing can receive it and the shipping
2:30:52
billing can receive it and the shipping
2:30:52
billing can receive it and the shipping can receive it. So the idea is that you
2:30:55
can receive it. So the idea is that you
2:30:55
can receive it. So the idea is that you can extend the system and even if there
2:30:57
can extend the system and even if there
2:30:57
can extend the system and even if there are failures the request is safely and
2:31:00
are failures the request is safely and
2:31:00
are failures the request is safely and durably stored somewhere be it the error
2:31:02
durably stored somewhere be it the error
2:31:02
durably stored somewhere be it the error Q so that you can bring things back up
2:31:04
Q so that you can bring things back up
2:31:04
Q so that you can bring things back up and retry it. So you're not losing any
2:31:07
and retry it. So you're not losing any
2:31:07
and retry it. So you're not losing any message. You are building that
2:31:09
message. You are building that
2:31:09
message. You are building that difference in place so that nothing is
2:31:10
difference in place so that nothing is
2:31:10
difference in place so that nothing is lost. Similarly, we can select all and
2:31:13
lost. Similarly, we can select all and
2:31:13
lost. Similarly, we can select all and retry and it should all go through
2:31:15
retry and it should all go through
2:31:16
retry and it should all go through without overwhelming the system or it
2:31:18
without overwhelming the system or it
2:31:18
without overwhelming the system or it should at least if processed one by
2:31:22
one. So we shall see that in action any
2:31:25
one. So we shall see that in action any
2:31:25
one. So we shall see that in action any minute. So I'm just going to move on and
2:31:28
minute. So I'm just going to move on and
2:31:28
minute. So I'm just going to move on and we can come back to it and visit the
2:31:30
we can come back to it and visit the
2:31:30
we can come back to it and visit the logs later. So we discussed all of this
2:31:32
logs later. So we discussed all of this
2:31:32
logs later. So we discussed all of this endpoints commands and pointto-point
2:31:34
endpoints commands and pointto-point
2:31:34
endpoints commands and pointto-point communication events in publish and
2:31:36
communication events in publish and
2:31:36
communication events in publish and subscribe. We saw about how you can
2:31:37
subscribe. We saw about how you can
2:31:38
subscribe. We saw about how you can extend your system without impacting the
2:31:39
extend your system without impacting the
2:31:39
extend your system without impacting the rest of the system. We saw about
2:31:41
rest of the system. We saw about
2:31:41
rest of the system. We saw about recoverability and retries. So we have
2:31:44
recoverability and retries. So we have
2:31:44
recoverability and retries. So we have moved on from that very monolithic
2:31:47
moved on from that very monolithic
2:31:47
moved on from that very monolithic architecture to something like this. So
2:31:48
architecture to something like this. So
2:31:48
architecture to something like this. So you have the client UI which publishes
2:31:51
you have the client UI which publishes
2:31:51
you have the client UI which publishes sorry not publishes it sends a command
2:31:53
sorry not publishes it sends a command
2:31:53
sorry not publishes it sends a command saying place order to the sales
2:31:55
saying place order to the sales
2:31:55
saying place order to the sales endpoint. The sales endpoint then
2:31:57
endpoint. The sales endpoint then
2:31:57
endpoint. The sales endpoint then publishes an event called order placed
2:32:00
publishes an event called order placed
2:32:00
publishes an event called order placed which is consumed by both billing and
2:32:02
which is consumed by both billing and
2:32:02
which is consumed by both billing and shipping. And here it gets interesting
2:32:05
shipping. And here it gets interesting
2:32:05
shipping. And here it gets interesting because the billing can then produce
2:32:07
because the billing can then produce
2:32:07
because the billing can then produce further events to say I have built the
2:32:09
further events to say I have built the
2:32:09
further events to say I have built the order. At which point the shipping can
2:32:11
order. At which point the shipping can
2:32:12
order. At which point the shipping can chip in and say you have placed the
2:32:13
chip in and say you have placed the
2:32:13
chip in and say you have placed the order, the order is confirmed, you have
2:32:16
order, the order is confirmed, you have
2:32:16
order, the order is confirmed, you have built the order. um I might also want to
2:32:19
built the order. um I might also want to
2:32:19
built the order. um I might also want to wait for the say the the stock service
2:32:21
wait for the say the the stock service
2:32:21
wait for the say the the stock service to come back and tell me that there is
2:32:23
to come back and tell me that there is
2:32:23
to come back and tell me that there is enough stock so that I can start the
2:32:25
enough stock so that I can start the
2:32:25
enough stock so that I can start the shipping. So that is a very complicated
2:32:28
shipping. So that is a very complicated
2:32:28
shipping. So that is a very complicated thing happening behind the scenes and
2:32:29
thing happening behind the scenes and
2:32:29
thing happening behind the scenes and that is yet another integration pattern
2:32:31
that is yet another integration pattern
2:32:31
that is yet another integration pattern called the saga pattern which you might
2:32:33
called the saga pattern which you might
2:32:33
called the saga pattern which you might want to invest and investigate and that
2:32:36
want to invest and investigate and that
2:32:36
want to invest and investigate and that is used for having uh or creating
2:32:38
is used for having uh or creating
2:32:38
is used for having uh or creating workflows. Further, the billing might uh
2:32:42
workflows. Further, the billing might uh
2:32:42
workflows. Further, the billing might uh publish the the same order build event
2:32:44
publish the the same order build event
2:32:44
publish the the same order build event that the billing published. It might be
2:32:46
that the billing published. It might be
2:32:46
that the billing published. It might be used by the email service to pick up the
2:32:48
used by the email service to pick up the
2:32:48
used by the email service to pick up the fact that a confirmation email needs to
2:32:50
fact that a confirmation email needs to
2:32:50
fact that a confirmation email needs to go on to the customer. And finally, the
2:32:53
go on to the customer. And finally, the
2:32:53
go on to the customer. And finally, the order build that could be picked up by
2:32:55
order build that could be picked up by
2:32:55
order build that could be picked up by the customer loyalty service to say that
2:32:57
the customer loyalty service to say that
2:32:57
the customer loyalty service to say that yep uh I haveated the customer
2:33:02
yep uh I haveated the customer
2:33:02
yep uh I haveated the customer loyalty database or the details of the
2:33:05

We are tackling bandwidth by achieving
2:34:27
We are tackling bandwidth by achieving some load leveling because backend
2:34:29
some load leveling because backend
2:34:29
some load leveling because backend systems could process at a normal rate
2:34:31
systems could process at a normal rate
2:34:31
systems could process at a normal rate while the the client UI alone is scaled.
2:34:34
while the the client UI alone is scaled.
2:34:34
while the the client UI alone is scaled. So there's load leveling
2:34:37
So there's load leveling
2:34:37
So there's load leveling happening. The network is secure because

they they all can work independently and
2:35:12
they they all can work independently and have team
2:35:13
have team
2:35:13
have team autonomy. We can scale just the

scenes and look at your demo. I just Thank you very much. It's been a while
2:36:38
Thank you very much. It's been a while
2:36:38
Thank you very much. It's been a while I've seen a such a fastpaced demo and
2:36:41
I've seen a such a fastpaced demo and
2:36:41
I've seen a such a fastpaced demo and yet it was so good. Uh there were no
2:36:44
yet it was so good. Uh there were no
2:36:44
yet it was so good. Uh there were no demo demons. I think I even if there was
2:36:47
demo demons. I think I even if there was
2:36:47
demo demons. I think I even if there was a demo demon, I didn't really realize
2:36:49
a demo demon, I didn't really realize
2:36:49
a demo demon, I didn't really realize it. Uh but it was it was very good. I
2:36:51
it. Uh but it was it was very good. I
2:36:51
it. Uh but it was it was very good. I know we have Elvin waiting behind the
2:36:53
know we have Elvin waiting behind the
2:36:54
know we have Elvin waiting behind the scenes and we have quite a few
2:36:55
scenes and we have quite a few
2:36:55
scenes and we have quite a few questions. Yes, maybe let's take at
2:36:56
questions. Yes, maybe let's take at
2:36:56
questions. Yes, maybe let's take at least one, right? Let's take one maybe
2:36:59
least one, right? Let's take one maybe
2:36:59
least one, right? Let's take one maybe um um um who let's say take him this
2:37:02
um um um who let's say take him this
2:37:02
um um um who let's say take him this time. It's he's asking how do you ensure
2:37:04
time. It's he's asking how do you ensure
2:37:04
time. It's he's asking how do you ensure message reliability and avoid issues
2:37:07
message reliability and avoid issues
2:37:07
message reliability and avoid issues like message loss or duplication
2:37:09
like message loss or duplication
2:37:09
like message loss or duplication especially during high traffic. Okay,
2:37:12
especially during high traffic. Okay,
2:37:12
especially during high traffic. Okay, these are two very different things.
2:37:14
these are two very different things.
2:37:14
these are two very different things. Message loss Yeah, rely on a messaging
2:37:17
Message loss Yeah, rely on a messaging
2:37:17
Message loss Yeah, rely on a messaging library. Please let the messaging
2:37:19
library. Please let the messaging
2:37:19
library. Please let the messaging library take care of you. Uh because
2:37:22
library take care of you. Uh because
2:37:22
library take care of you. Uh because that's not something that you can handle
2:37:23
that's not something that you can handle
2:37:23
that's not something that you can handle yourself. There is message cues but you
2:37:26
yourself. There is message cues but you
2:37:26
yourself. There is message cues but you need to make sure that you need to focus
2:37:28
need to make sure that you need to focus
2:37:28
need to make sure that you need to focus on your business code. So use a message
2:37:30
on your business code. So use a message
2:37:30
on your business code. So use a message library that will take care of the
2:37:31
library that will take care of the
2:37:31
library that will take care of the messages for you. Now when it comes to
2:37:33
messages for you. Now when it comes to
2:37:33
messages for you. Now when it comes to duplication that is yet another pattern
2:37:35
duplication that is yet another pattern
2:37:35
duplication that is yet another pattern that you can invest in which is the
2:37:37
that you can invest in which is the
2:37:37
that you can invest in which is the outbox pattern. So that takes care of
2:37:40
outbox pattern. So that takes care of
2:37:40
outbox pattern. So that takes care of exactly one's processing and make sure
2:37:41
exactly one's processing and make sure
2:37:42
exactly one's processing and make sure that there's deed replication and item
2:37:44
that there's deed replication and item
2:37:44
that there's deed replication and item potential of your data. It's not
2:37:45
potential of your data. It's not
2:37:45
potential of your data. It's not something that I can explain in five
2:37:47
something that I can explain in five
2:37:47
something that I can explain in five minutes because it is really really
2:37:49
minutes because it is really really
2:37:49
minutes because it is really really really advanced as a topic something
2:37:52
really advanced as a topic something
2:37:52
really advanced as a topic something which needs one hour but I have
2:37:55
which needs one hour but I have
2:37:55
which needs one hour but I have something for the audience who asked me
2:37:58
something for the audience who asked me
2:37:58
something for the audience who asked me about it. Um it is a podcast that I'm
2:38:02
about it. Um it is a podcast that I'm

2:42:12
talk, but all of the slides for
2:42:12
talk, but all of the slides for everything and all of the code samples
2:42:14
everything and all of the code samples
2:42:14
everything and all of the code samples are all up in my GitHub repo. It's just
2:42:16
are all up in my GitHub repo. It's just
2:42:16
are all up in my GitHub repo. It's just Alvin
2:42:18
Alvin
2:42:18
Alvin Ashcraftspeaking. So you can go up to
2:42:19
Ashcraftspeaking. So you can go up to
2:42:19
Ashcraftspeaking. So you can go up to GitHub and uh get the resources for all
2:42:21
GitHub and uh get the resources for all
2:42:22
GitHub and uh get the resources for all of these
2:42:26
demos. So let's start with a quick
2:42:28
demos. So let's start with a quick
2:42:28
demos. So let's start with a quick overview of WinUI and then we'll get in
2:42:30
overview of WinUI and then we'll get in
2:42:30
overview of WinUI and then we'll get in some code quickly here. Uh so WinUI is
2:42:33
some code quickly here. Uh so WinUI is
2:42:33
some code quickly here. Uh so WinUI is part of the Windows app SDK. Um the
2:42:36
part of the Windows app SDK. Um the
2:42:36
part of the Windows app SDK. Um the first release was in March of 2021. That
2:42:39
first release was in March of 2021. That
2:42:39
first release was in March of 2021. That was 1.0. Uh WinUI3, they call it WinUI3,
2:42:42
was 1.0. Uh WinUI3, they call it WinUI3,
2:42:42
was 1.0. Uh WinUI3, they call it WinUI3, but it's not really a version number. uh
2:42:44
but it's not really a version number. uh
2:42:44
but it's not really a version number. uh it's kind of the successor to WinUI 2
2:42:48
it's kind of the successor to WinUI 2
2:42:48
it's kind of the successor to WinUI 2 which was an add-on to UWP to add some
2:42:51
which was an add-on to UWP to add some
2:42:51
which was an add-on to UWP to add some additional controls and libraries and
2:42:53
additional controls and libraries and
2:42:53
additional controls and libraries and WinUI3 is completely its own thing with
2:42:55
WinUI3 is completely its own thing with
2:42:55
WinUI3 is completely its own thing with the Windows app SDK. It's very similar
2:42:57
the Windows app SDK. It's very similar
2:42:57
the Windows app SDK. It's very similar to UWP if you've done a UWP apps on
2:43:00
to UWP if you've done a UWP apps on
2:43:00
to UWP if you've done a UWP apps on Windows 10. Uh what they did was they
2:43:03
Windows 10. Uh what they did was they
2:43:03
Windows 10. Uh what they did was they took those controls and libraries and
2:43:06
took those controls and libraries and
2:43:06
took those controls and libraries and extracted them from the Windows SDK so
2:43:08
extracted them from the Windows SDK so
2:43:08
extracted them from the Windows SDK so that they could version these components
2:43:11
that they could version these components
2:43:11
that they could version these components independent of Windows. they used to be
2:43:13
independent of Windows. they used to be
2:43:13
independent of Windows. they used to be stuck with waiting for a new Windows
2:43:15
stuck with waiting for a new Windows
2:43:15
stuck with waiting for a new Windows release before you could get new UWP
2:43:17
release before you could get new UWP
2:43:17
release before you could get new UWP features and now it's all separated out.
2:43:19
features and now it's all separated out.
2:43:20
features and now it's all separated out. Uh the main difference between UWP and
2:43:23
Uh the main difference between UWP and
2:43:24
Uh the main difference between UWP and Win UI as far as looking at the code is
2:43:26
Win UI as far as looking at the code is
2:43:26
Win UI as far as looking at the code is uh the name spaces are changed. So
2:43:27
uh the name spaces are changed. So
2:43:27
uh the name spaces are changed. So everything starts with Microsoft dot
2:43:29
everything starts with Microsoft dot
2:43:29
everything starts with Microsoft dot instead of Windows dot in the name
2:43:33
instead of Windows dot in the name
2:43:33
instead of Windows dot in the name spaces. Um it's built on the latest .NET
2:43:35
spaces. Um it's built on the latest .NET
2:43:35
spaces. Um it's built on the latest .NET runtime. Right now you can build WinUI
2:43:37
runtime. Right now you can build WinUI
2:43:37
runtime. Right now you can build WinUI apps with .NET 9 or .NET 8. Both are
2:43:40
apps with .NET 9 or .NET 8. Both are
2:43:40
apps with .NET 9 or .NET 8. Both are still supported.
2:43:42
still supported.
2:43:42
still supported. um you create apps with ZAML and either
2:43:44
um you create apps with ZAML and either
2:43:44
um you create apps with ZAML and either C or C++ and if you use C you're also
2:43:48
C or C++ and if you use C you're also
2:43:48
C or C++ and if you use C you're also using uh .NET and you have access to the
2:43:50
using uh .NET and you have access to the
2:43:50
using uh .NET and you have access to the full uh net libraries, runtimes,
2:43:54
full uh net libraries, runtimes,
2:43:54
full uh net libraries, runtimes, everything. And the latest release of
2:43:56
everything. And the latest release of
2:43:56
everything. And the latest release of Windows App SDK is 1.7 that just came
2:43:59
Windows App SDK is 1.7 that just came
2:43:59
Windows App SDK is 1.7 that just came out about 3 weeks
2:44:00
out about 3 weeks
2:44:01
out about 3 weeks ago. And it's open source on GitHub, not
2:44:04
ago. And it's open source on GitHub, not
2:44:04
ago. And it's open source on GitHub, not full open source. You can't uh
2:44:06
full open source. You can't uh
2:44:06
full open source. You can't uh contribute code yourself, but they do
2:44:07
contribute code yourself, but they do
2:44:08
contribute code yourself, but they do publish readonly um versions of the code
2:44:10
publish readonly um versions of the code
2:44:10
publish readonly um versions of the code so that it helps with debugging. You can
2:44:12
so that it helps with debugging. You can
2:44:12
so that it helps with debugging. You can get access to all the
2:44:16
source. And let's see, we're going to
2:44:18
source. And let's see, we're going to
2:44:18
source. And let's see, we're going to dive into the first demo here. Uh, so
2:44:20
dive into the first demo here. Uh, so
2:44:20
dive into the first demo here. Uh, so there's going to be uh two parts to this
2:44:22
there's going to be uh two parts to this
2:44:22
there's going to be uh two parts to this demo. So I'm going to create a new WinUI
2:44:24
demo. So I'm going to create a new WinUI
2:44:24
demo. So I'm going to create a new WinUI project from scratch and then show you
2:44:27
project from scratch and then show you
2:44:27
project from scratch and then show you how you can add a couple of things to
2:44:28
how you can add a couple of things to
2:44:28
how you can add a couple of things to make it look a little bit nicer. And
2:44:30
make it look a little bit nicer. And
2:44:30
make it look a little bit nicer. And then I will open up another project
2:44:32
then I will open up another project
2:44:32
then I will open up another project that's got uh an MVVM implementation
2:44:35
that's got uh an MVVM implementation
2:44:35
that's got uh an MVVM implementation model view view model. And it's also got
2:44:37
model view view model. And it's also got
2:44:37
model view view model. And it's also got some controls and some styles added so
2:44:40
some controls and some styles added so
2:44:40
some controls and some styles added so you can see uh the difference between
2:44:41
you can see uh the difference between
2:44:41
you can see uh the difference between the the basic out of the box and what
2:44:44
the the basic out of the box and what
2:44:44
the the basic out of the box and what you can do pretty easily just adding a
2:44:45
you can do pretty easily just adding a
2:44:45
you can do pretty easily just adding a few styles and controls to your app. But
2:44:48
few styles and controls to your app. But
2:44:48
few styles and controls to your app. But let's start with a new project dialogue.
2:44:51
let's start with a new project dialogue.
2:44:51
let's start with a new project dialogue. We'll create a new project in Visual
2:44:58
Studio. And we're going to pick a blank
2:45:01
Studio. And we're going to pick a blank
2:45:01
Studio. And we're going to pick a blank app packaged
2:45:03
app packaged
2:45:03
app packaged WinUI3. And this is
2:45:07
C. And we'll just leave the name app 3
2:45:10
C. And we'll just leave the name app 3
2:45:10
C. And we'll just leave the name app 3 for
2:45:12
for
2:45:12
for now. And hit create.
2:45:23
So, this loads up a couple of files here
2:45:25
So, this loads up a couple of files here
2:45:25
So, this loads up a couple of files here in your your project.
2:45:29
See, if we zoom in a little bit there,
2:45:32
See, if we zoom in a little bit there,
2:45:32
See, if we zoom in a little bit there, you can see this better. Um, so we've
2:45:34
you can see this better. Um, so we've
2:45:34
you can see this better. Um, so we've got an app manifest. We've got an
2:45:37
got an app manifest. We've got an
2:45:37
got an app manifest. We've got an app.zaml, which is the part of the
2:45:40
app.zaml, which is the part of the
2:45:40
app.zaml, which is the part of the program that launches your app. So it
2:45:42
program that launches your app. So it
2:45:42
program that launches your app. So it goes into the app class first and then
2:45:44
goes into the app class first and then
2:45:44
goes into the app class first and then launches the main window from there. And
2:45:47
launches the main window from there. And
2:45:47
launches the main window from there. And the main window is exactly at the main
2:45:50
the main window is exactly at the main
2:45:50
the main window is exactly at the main window. Let's take a look in the
2:45:52
window. Let's take a look in the
2:45:52
window. Let's take a look in the app.zaml just for a second to see how
2:45:54
app.zaml just for a second to see how
2:45:54
app.zaml just for a second to see how that's
2:45:57
created. So in the on launch method, it
2:46:00
created. So in the on launch method, it
2:46:00
created. So in the on launch method, it just creates a new instance of the main
2:46:02
just creates a new instance of the main
2:46:02
just creates a new instance of the main window and activates it.
2:46:05
window and activates it.
2:46:05
window and activates it. And then in the main
2:46:07
And then in the main
2:46:07
And then in the main window, the new project just gives you a
2:46:10
window, the new project just gives you a
2:46:10
window, the new project just gives you a blank window with a single stack panel.
2:46:13
blank window with a single stack panel.
2:46:13
blank window with a single stack panel. Stack panel just uh does exactly that.
2:46:15
Stack panel just uh does exactly that.
2:46:15
Stack panel just uh does exactly that. Anything you put inside there, it'll
2:46:17
Anything you put inside there, it'll
2:46:17
Anything you put inside there, it'll just stack the controls either
2:46:19
just stack the controls either
2:46:19
just stack the controls either horizontally or vertically depending how
2:46:21
horizontally or vertically depending how
2:46:21
horizontally or vertically depending how you set that up. So this one is
2:46:24
you set that up. So this one is
2:46:24
you set that up. So this one is horizontal. So it would stack things um
2:46:26
horizontal. So it would stack things um
2:46:26
horizontal. So it would stack things um left
2:46:28
left
2:46:28
left right. And then in the code
2:46:31
right. And then in the code
2:46:31
right. And then in the code behind, each ZAML file has a C# code
2:46:34
behind, each ZAML file has a C# code
2:46:34
behind, each ZAML file has a C# code behind file where you can put code. Um,
2:46:38
behind file where you can put code. Um,
2:46:38
behind file where you can put code. Um, so here there's just a buttonclick event
2:46:40
so here there's just a buttonclick event
2:46:40
so here there's just a buttonclick event handler. So when you click the button
2:46:42
handler. So when you click the button
2:46:42
handler. So when you click the button that's in this UI file, it'll call that
2:46:45
that's in this UI file, it'll call that
2:46:45
that's in this UI file, it'll call that event handler. Let's just run this. I'm
2:46:48
event handler. Let's just run this. I'm
2:46:48
event handler. Let's just run this. I'm going to change this to ARM 64. I have
2:46:49
going to change this to ARM 64. I have
2:46:49
going to change this to ARM 64. I have an ARM laptop
2:46:51
an ARM laptop
2:46:51
an ARM laptop here. Run it with no changes and see how
2:46:54
here. Run it with no changes and see how
2:46:54
here. Run it with no changes and see how it looks.
2:47:01
It's building and
2:47:06
deploying. And it's pretty basic. It's a
2:47:08
deploying. And it's pretty basic. It's a
2:47:08
deploying. And it's pretty basic. It's a big empty window except for the one
2:47:10
big empty window except for the one
2:47:10
big empty window except for the one click me button there. And you can see
2:47:12
click me button there. And you can see
2:47:12
click me button there. And you can see it's got a title bar with a no icon yet.
2:47:16
it's got a title bar with a no icon yet.
2:47:16
it's got a title bar with a no icon yet. I click that, it just changes it to
2:47:17
I click that, it just changes it to
2:47:18
I click that, it just changes it to clicked.
2:47:20
clicked.
2:47:20
clicked. And now I want to show you a couple of
2:47:22
And now I want to show you a couple of
2:47:22
And now I want to show you a couple of quick things you can do to make
2:47:24
quick things you can do to make
2:47:24
quick things you can do to make your window look a little bit nicer. I
2:47:27
your window look a little bit nicer. I
2:47:27
your window look a little bit nicer. I have this other app
2:47:29
have this other app
2:47:29
have this other app here. And this is exactly the same code
2:47:32
here. And this is exactly the same code
2:47:32
here. And this is exactly the same code except I've added a few extra things. So
2:47:35
except I've added a few extra things. So
2:47:35
except I've added a few extra things. So the first thing I've added is this Micah
2:47:37
the first thing I've added is this Micah
2:47:37
the first thing I've added is this Micah backdrop. And what that does is it gives
2:47:39
backdrop. And what that does is it gives
2:47:39
backdrop. And what that does is it gives it a little bit more of that Windows 11
2:47:42
it a little bit more of that Windows 11
2:47:42
it a little bit more of that Windows 11 look and feel. I'm going to take that
2:47:45
look and feel. I'm going to take that
2:47:45
look and feel. I'm going to take that and just paste it in our new project and
2:47:48
and just paste it in our new project and
2:47:48
and just paste it in our new project and run this again. So you can see the
2:47:49
run this again. So you can see the
2:47:49
run this again. So you can see the difference that one little uh attribute
2:47:52
difference that one little uh attribute
2:47:52
difference that one little uh attribute makes
2:47:54
there. You can see it kind of has that
2:47:56
there. You can see it kind of has that
2:47:56
there. You can see it kind of has that pinkish hue now. So it's almost like a
2:47:59
pinkish hue now. So it's almost like a
2:47:59
pinkish hue now. So it's almost like a it's picking up the color of your
2:48:01
it's picking up the color of your
2:48:01
it's picking up the color of your wallpaper in the background. So I've got
2:48:03
wallpaper in the background. So I've got
2:48:04
wallpaper in the background. So I've got a a purplish hazy background and it's
2:48:06
a a purplish hazy background and it's
2:48:06
a a purplish hazy background and it's pulling that into the window
2:48:09
pulling that into the window
2:48:09
pulling that into the window here. Let's stop this and go grab the
2:48:12
here. Let's stop this and go grab the
2:48:12
here. Let's stop this and go grab the other piece that I have here. So the
2:48:15
other piece that I have here. So the
2:48:15
other piece that I have here. So the rest of this, so instead of just the
2:48:17
rest of this, so instead of just the
2:48:17
rest of this, so instead of just the stack panel, I have a grid wrapping it.
2:48:19
stack panel, I have a grid wrapping it.
2:48:19
stack panel, I have a grid wrapping it. And I have two rows in the grid. The
2:48:21
And I have two rows in the grid. The
2:48:21
And I have two rows in the grid. The first one has a custom title bar. And
2:48:24
first one has a custom title bar. And
2:48:24
first one has a custom title bar. And this is a new thing in Windows app SDK
2:48:27
this is a new thing in Windows app SDK
2:48:27
this is a new thing in Windows app SDK 1.7. It's a title bar that looks a
2:48:30
1.7. It's a title bar that looks a
2:48:30
1.7. It's a title bar that looks a little bit more like what you see in
2:48:31
little bit more like what you see in
2:48:31
little bit more like what you see in other Windows apps. Uh you can add more
2:48:34
other Windows apps. Uh you can add more
2:48:34
other Windows apps. Uh you can add more things into the the title bar like
2:48:37
things into the the title bar like
2:48:37
things into the the title bar like you'll see in this WinUI3 gallery
2:48:40
you'll see in this WinUI3 gallery
2:48:40
you'll see in this WinUI3 gallery app. You know, it looks like a little
2:48:42
app. You know, it looks like a little
2:48:42
app. You know, it looks like a little bit bigger. It's got a nice icon here.
2:48:45
bit bigger. It's got a nice icon here.
2:48:45
bit bigger. It's got a nice icon here. It's got a back button in here. And
2:48:48
It's got a back button in here. And
2:48:48
It's got a back button in here. And you'll see some apps like the store,
2:48:49
you'll see some apps like the store,
2:48:49
you'll see some apps like the store, they have each they even have like a
2:48:51
they have each they even have like a
2:48:51
they have each they even have like a search box up in your title bar. You can
2:48:53
search box up in your title bar. You can
2:48:53
search box up in your title bar. You can do all that with this new title bar
2:48:55
do all that with this new title bar
2:48:55
do all that with this new title bar control. Let's go back to this
2:48:58
control. Let's go back to this
2:48:58
control. Let's go back to this app, copy this, and put it in
2:49:04
here. So, we've added this new title
2:49:08
here. So, we've added this new title
2:49:08
here. So, we've added this new title bar. I'll call this sample app. that
2:49:11
bar. I'll call this sample app. that
2:49:12
bar. I'll call this sample app. that we'll put that in the title
2:49:13
we'll put that in the title
2:49:13
we'll put that in the title bar. I'm hiding the back button and I'm
2:49:16
bar. I'm hiding the back button and I'm
2:49:16
bar. I'm hiding the back button and I'm not making it a tab stop because we
2:49:18
not making it a tab stop because we
2:49:18
not making it a tab stop because we don't have any controls up there that we
2:49:19
don't have any controls up there that we
2:49:20
don't have any controls up there that we want the user be to be able to tab
2:49:23
want the user be to be able to tab
2:49:23
want the user be to be able to tab into. And I have to get one other piece
2:49:25
into. And I have to get one other piece
2:49:25
into. And I have to get one other piece to make that work. In the code
2:49:28
to make that work. In the code
2:49:28
to make that work. In the code behind, there's a set title bar method
2:49:32
behind, there's a set title bar method
2:49:32
behind, there's a set title bar method that we're going to copy and call that
2:49:34
that we're going to copy and call that
2:49:34
that we're going to copy and call that from the constructor.
2:49:39
So, let's paste that in
2:49:46
here and call
2:49:49
here and call
2:49:49
here and call it. And so here, you'll see I'm setting
2:49:52
it. And so here, you'll see I'm setting
2:49:52
it. And so here, you'll see I'm setting the icon. I'm telling it to make it the
2:49:55
the icon. I'm telling it to make it the
2:49:55
the icon. I'm telling it to make it the taller
2:49:57
taller
2:49:57
taller height and setting the display name here
2:50:00
height and setting the display name here
2:50:00
height and setting the display name here as well. Let's run this again.
2:50:07
And if we did everything right, we
2:50:09
And if we did everything right, we
2:50:09
And if we did everything right, we should have this nice all title bar. But
2:50:12
should have this nice all title bar. But
2:50:12
should have this nice all title bar. But we don't have the icon yet because I
2:50:14
we don't have the icon yet because I
2:50:14
we don't have the icon yet because I forgot that step. Let's get our icon in
2:50:17
forgot that step. Let's get our icon in
2:50:17
forgot that step. Let's get our icon in here. Add it to the assets
2:50:19
here. Add it to the assets
2:50:19
here. Add it to the assets folder. We're going to add an existing
2:50:23
folder. We're going to add an existing
2:50:23
folder. We're going to add an existing item. going to browse out to this other
2:50:26
item. going to browse out to this other
2:50:26
item. going to browse out to this other place where I have an
2:50:31
icon and it's a winui
2:50:34
icon and it's a winui
2:50:34
icon and it's a winui icon. Now we've got
2:50:39
that. I got to do one more thing. We'll
2:50:42
that. I got to do one more thing. We'll
2:50:42
that. I got to do one more thing. We'll stop that.
2:50:46
We have to go and set the properties on
2:50:49
We have to go and set the properties on
2:50:49
We have to go and set the properties on this so that we set it as
2:50:52
this so that we set it as
2:50:52
this so that we set it as content. Instead of build action none,
2:50:55
content. Instead of build action none,
2:50:55
content. Instead of build action none, we're going to say build action content
2:50:57
we're going to say build action content
2:50:57
we're going to say build action content so that we can reference it in the
2:51:04
code. Now we should have an icon when
2:51:06
code. Now we should have an icon when
2:51:06
code. Now we should have an icon when this launches. There it is. We've got
2:51:08
this launches. There it is. We've got
2:51:08
this launches. There it is. We've got the larger title bar. Looks a little bit
2:51:10
the larger title bar. Looks a little bit
2:51:10
the larger title bar. Looks a little bit nicer. And we got the icon set there.
2:51:16
nicer. And we got the icon set there.
2:51:16
nicer. And we got the icon set there. and it still works just like expected.
2:51:18
and it still works just like expected.
2:51:18
and it still works just like expected. When you hit the button, it says
2:51:23
clicked. So, that's a basic app. I'm
2:51:26
clicked. So, that's a basic app. I'm
2:51:26
clicked. So, that's a basic app. I'm going to pull up something with a little
2:51:28
going to pull up something with a little
2:51:28
going to pull up something with a little bit more to it.
2:51:30
bit more to it.
2:51:30
bit more to it. Now, these are all the samples that are
2:51:33
Now, these are all the samples that are
2:51:33
Now, these are all the samples that are out of my GitHub repo. We're going to
2:51:34
out of my GitHub repo. We're going to
2:51:34
out of my GitHub repo. We're going to start with this controls and MBBM
2:51:36
start with this controls and MBBM
2:51:36
start with this controls and MBBM solution.
2:51:45
And in here you can see I've got a lot
2:51:46
And in here you can see I've got a lot
2:51:46
And in here you can see I've got a lot more going on. So we have still have a
2:51:48
more going on. So we have still have a
2:51:48
more going on. So we have still have a main window and an app.zaml, but we also
2:51:51
main window and an app.zaml, but we also
2:51:51
main window and an app.zaml, but we also have some other views and view
2:51:55
have some other views and view
2:51:55
have some other views and view models. So in the main window
2:51:59
models. So in the main window
2:51:59
models. So in the main window now you'll see there's nothing in there.
2:52:01
now you'll see there's nothing in there.
2:52:01
now you'll see there's nothing in there. It's just a window with the micica
2:52:04
It's just a window with the micica
2:52:04
It's just a window with the micica backdrop.
2:52:06
backdrop.
2:52:06
backdrop. So in here, instead of having the uh
2:52:09
So in here, instead of having the uh
2:52:09
So in here, instead of having the uh everything in the main window, we're
2:52:11
everything in the main window, we're
2:52:11
everything in the main window, we're loading each of these other views as a
2:52:13
loading each of these other views as a
2:52:13
loading each of these other views as a page inside the
2:52:16
page inside the
2:52:16
page inside the window. So all of my markup for what
2:52:20
window. So all of my markup for what
2:52:20
window. So all of my markup for what we're going to be launching is here in
2:52:21
we're going to be launching is here in
2:52:21
we're going to be launching is here in the main page. And this main page will
2:52:24
the main page. And this main page will
2:52:24
the main page. And this main page will get
2:52:25
get
2:52:25
get loaded, I believe, in the app.zaml.
2:52:27
loaded, I believe, in the app.zaml.
2:52:27
loaded, I believe, in the app.zaml. Let's take a look here.
2:52:33
So on launched, we're creating main
2:52:36
So on launched, we're creating main
2:52:36
So on launched, we're creating main window and we're adding a frame to the
2:52:39
window and we're adding a frame to the
2:52:39
window and we're adding a frame to the window and then we're adding we're
2:52:42
window and then we're adding we're
2:52:42
window and then we're adding we're telling it to navigate to the main page
2:52:43
telling it to navigate to the main page
2:52:43
telling it to navigate to the main page within that
2:52:46
within that
2:52:46
within that frame. Let's before we dive into any
2:52:48
frame. Let's before we dive into any
2:52:48
frame. Let's before we dive into any more code, let's just launch this and
2:52:49
more code, let's just launch this and
2:52:50
more code, let's just launch this and show you what we're dealing
2:52:57
with. So this is a media collection app.
2:53:00
with. So this is a media collection app.
2:53:00
with. So this is a media collection app. So you can enter in your CDs, you know,
2:53:03
So you can enter in your CDs, you know,
2:53:03
So you can enter in your CDs, you know, books, Blu-rays, DVDs. You can enter all
2:53:06
books, Blu-rays, DVDs. You can enter all
2:53:06
books, Blu-rays, DVDs. You can enter all that media here and create your
2:53:08
that media here and create your
2:53:08
that media here and create your collection. It's got a dropown box to
2:53:10
collection. It's got a dropown box to
2:53:10
collection. It's got a dropown box to filter by type. So if you only want to
2:53:12
filter by type. So if you only want to
2:53:12
filter by type. So if you only want to see books, it'll show that. Or I can go
2:53:15
see books, it'll show that. Or I can go
2:53:15
see books, it'll show that. Or I can go back and show
2:53:17
all. I can select items. I can edit it
2:53:21
all. I can select items. I can edit it
2:53:21
all. I can select items. I can edit it or I can delete it. If I don't have
2:53:23
or I can delete it. If I don't have
2:53:23
or I can delete it. If I don't have anything selected, I can add items.
2:53:25
anything selected, I can add items.
2:53:25
anything selected, I can add items. Let's hit edit.
2:53:27
Let's hit edit.
2:53:27
Let's hit edit. And one of the other cool controls here
2:53:29
And one of the other cool controls here
2:53:29
And one of the other cool controls here is this teaching tip. So what you can do
2:53:31
is this teaching tip. So what you can do
2:53:32
is this teaching tip. So what you can do with a teaching tip uh by default it'll
2:53:34
with a teaching tip uh by default it'll
2:53:34
with a teaching tip uh by default it'll show every time, but you can add a user
2:53:35
show every time, but you can add a user
2:53:35
show every time, but you can add a user preference
2:53:37
preference
2:53:37
preference um to save whether the user has already
2:53:39
um to save whether the user has already
2:53:39
um to save whether the user has already seen this tip. So once they've seen it
2:53:41
seen this tip. So once they've seen it
2:53:41
seen this tip. So once they've seen it one time, you don't show it to them
2:53:42
one time, you don't show it to them
2:53:42
one time, you don't show it to them again. It's just telling them how this
2:53:45
again. It's just telling them how this
2:53:45
again. It's just telling them how this drop down button works. So they can save
2:53:47
drop down button works. So they can save
2:53:47
drop down button works. So they can save and create new or save and return once
2:53:49
and create new or save and return once
2:53:49
and create new or save and return once they've made a change here. So let's say
2:53:52
they've made a change here. So let's say
2:53:52
they've made a change here. So let's say this is no longer in my collection. I've
2:53:53
this is no longer in my collection. I've
2:53:53
this is no longer in my collection. I've loaned it to
2:53:55
loaned it to
2:53:55
loaned it to somebody. Now I can hit this. So, I can
2:53:57
somebody. Now I can hit this. So, I can
2:53:57
somebody. Now I can hit this. So, I can either save and create a new item or I
2:53:59
either save and create a new item or I
2:53:59
either save and create a new item or I can save and return to the
2:54:02
list. Let's create
2:54:08
new. And we'll add an alien movie to our
2:54:11
new. And we'll add an alien movie to our
2:54:11
new. And we'll add an alien movie to our list, a
2:54:13
list, a
2:54:13
list, a video. Let's say it's a Blu-ray. And
2:54:16
video. Let's say it's a Blu-ray. And
2:54:16
video. Let's say it's a Blu-ray. And it's in our collection. Now, I can save
2:54:19
it's in our collection. Now, I can save
2:54:19
it's in our collection. Now, I can save and return. And we've got all four items
2:54:25
here. But let's take a look at some of
2:54:27
here. But let's take a look at some of
2:54:27
here. But let's take a look at some of the code for this and see how this
2:54:30
the code for this and see how this
2:54:30
the code for this and see how this works. So in the
2:54:32
works. So in the
2:54:32
works. So in the main
2:54:35
main
2:54:35
main page, we've got separate grid for the
2:54:38
page, we've got separate grid for the
2:54:38
page, we've got separate grid for the stuff at the top. So in the top, we've
2:54:41
stuff at the top. So in the top, we've
2:54:41
stuff at the top. So in the top, we've got the header. We've got a stack panel
2:54:43
got the header. We've got a stack panel
2:54:43
got the header. We've got a stack panel that stacks horizontally for the uh the
2:54:47
that stacks horizontally for the uh the
2:54:47
that stacks horizontally for the uh the label for the drop-own box that filters
2:54:49
label for the drop-own box that filters
2:54:49
label for the drop-own box that filters by type. And then the combo box itself.
2:54:53
by type. And then the combo box itself.
2:54:53
by type. And then the combo box itself. And this is using data binding. So we
2:54:55
And this is using data binding. So we
2:54:55
And this is using data binding. So we can bind to things in our view model to
2:54:59
can bind to things in our view model to
2:54:59
can bind to things in our view model to show them in the UI. So I'm binding the
2:55:01
show them in the UI. So I'm binding the
2:55:01
show them in the UI. So I'm binding the list of items to this list of mediums in
2:55:04
list of items to this list of mediums in
2:55:04
list of items to this list of mediums in the view model. And then I set the
2:55:06
the view model. And then I set the
2:55:06
the view model. And then I set the selected item based on that
2:55:09
selected item based on that
2:55:09
selected item based on that property. And then for the bottom part
2:55:11
property. And then for the bottom part
2:55:11
property. And then for the bottom part I'm using a list view control. And
2:55:14
I'm using a list view control. And
2:55:14
I'm using a list view control. And inside the list view I have both a
2:55:16
inside the list view I have both a
2:55:16
inside the list view I have both a template for the header and a template
2:55:18
template for the header and a template
2:55:18
template for the header and a template for each item in the list.
2:55:23
And you can see for the styling, uh,
2:55:25
And you can see for the styling, uh,
2:55:26
And you can see for the styling, uh, we're using theme resources. This will
2:55:28
we're using theme resources. This will
2:55:28
we're using theme resources. This will make sure it'll pick up the light and
2:55:30
make sure it'll pick up the light and
2:55:30
make sure it'll pick up the light and dark mode or any other color changes
2:55:32
dark mode or any other color changes
2:55:32
dark mode or any other color changes that the user makes in their system. If
2:55:34
that the user makes in their system. If
2:55:34
that the user makes in their system. If you wanted to instead brand it your own
2:55:37
you wanted to instead brand it your own
2:55:37
you wanted to instead brand it your own company colors or something, you could
2:55:39
company colors or something, you could
2:55:39
company colors or something, you could hardcode or create your own theme based
2:55:41
hardcode or create your own theme based
2:55:41
hardcode or create your own theme based on your your company uh logos and
2:55:44
on your your company uh logos and
2:55:44
on your your company uh logos and things.
2:55:47
And at the bottom we have another stack
2:55:49
And at the bottom we have another stack
2:55:49
And at the bottom we have another stack panel that's got the
2:55:52
buttons. These are both
2:55:56
buttons. These are both
2:55:56
buttons. These are both regular standard buttons and these are
2:55:59
regular standard buttons and these are
2:55:59
regular standard buttons and these are binding a command to the view model. So
2:56:02
binding a command to the view model. So
2:56:02
binding a command to the view model. So the um the command is what's going to be
2:56:05
the um the command is what's going to be
2:56:05
the um the command is what's going to be executed when you the user clicks on
2:56:07
executed when you the user clicks on
2:56:07
executed when you the user clicks on there. So it'll go into this addedit
2:56:10
there. So it'll go into this addedit
2:56:10
there. So it'll go into this addedit functionality or the delete. Let's take
2:56:13
functionality or the delete. Let's take
2:56:13
functionality or the delete. Let's take a look at the uh the view model that
2:56:15
a look at the uh the view model that
2:56:15
a look at the uh the view model that corresponds to
2:56:17
corresponds to
2:56:17
corresponds to this. So if you've done any uh ZAML
2:56:20
this. So if you've done any uh ZAML
2:56:20
this. So if you've done any uh ZAML development and used model view model,
2:56:22
development and used model view model,
2:56:22
development and used model view model, you may may have uh done your own
2:56:25
you may may have uh done your own
2:56:25
you may may have uh done your own implementation of uh an observable class
2:56:28
implementation of uh an observable class
2:56:28
implementation of uh an observable class or a bindable class. Uh I'm using the
2:56:32
or a bindable class. Uh I'm using the
2:56:32
or a bindable class. Uh I'm using the MVVM toolkit which is part of the net
2:56:35
MVVM toolkit which is part of the net
2:56:35
MVVM toolkit which is part of the net community toolkit. It's uh open source
2:56:38
community toolkit. It's uh open source
2:56:38
community toolkit. It's uh open source available up on GitHub. you can get
2:56:40
available up on GitHub. you can get
2:56:40
available up on GitHub. you can get references into your project through um
2:56:44
references into your project through um
2:56:44
references into your project through um Nougat. So if I look at our Nougat
2:56:46
Nougat. So if I look at our Nougat
2:56:46
Nougat. So if I look at our Nougat packages
2:56:49
here, let's see, I've got the MVVM
2:56:53
here, let's see, I've got the MVVM
2:56:53
here, let's see, I've got the MVVM toolkit and these are all other standard
2:56:57
toolkit and these are all other standard
2:56:57
toolkit and these are all other standard Win UI packages that you'll have
2:57:00
Win UI packages that you'll have
2:57:00
Win UI packages that you'll have here. So by using the MVVM toolkit, it
2:57:04
here. So by using the MVVM toolkit, it
2:57:04
here. So by using the MVVM toolkit, it reduces a lot of code that you'd
2:57:05
reduces a lot of code that you'd
2:57:05
reduces a lot of code that you'd normally have in your your view model.
2:57:08
normally have in your your view model.
2:57:08
normally have in your your view model. All I need to do is make my view model a
2:57:11
All I need to do is make my view model a
2:57:11
All I need to do is make my view model a partial class and inherit from
2:57:13
partial class and inherit from
2:57:13
partial class and inherit from observable object. And by doing that
2:57:16
observable object. And by doing that
2:57:16
observable object. And by doing that it's going to create it's uses source
2:57:19
it's going to create it's uses source
2:57:19
it's going to create it's uses source generators to create another partial
2:57:21
generators to create another partial
2:57:21
generators to create another partial class with the imple implementation of
2:57:23
class with the imple implementation of
2:57:23
class with the imple implementation of all the public members. So for a
2:57:26
all the public members. So for a
2:57:26
all the public members. So for a property I only need to create the
2:57:27
property I only need to create the
2:57:27
property I only need to create the private member the selected medium in
2:57:30
private member the selected medium in
2:57:30
private member the selected medium in this case and when it builds and runs
2:57:33
this case and when it builds and runs
2:57:33
this case and when it builds and runs it's going to create a public property
2:57:36
it's going to create a public property
2:57:36
it's going to create a public property called selected medium with a capital
2:57:39
called selected medium with a capital
2:57:39
called selected medium with a capital S. So anything that's decorated with
2:57:41
S. So anything that's decorated with
2:57:42
S. So anything that's decorated with observable property will create a
2:57:44
observable property will create a
2:57:44
observable property will create a corresponding public property for you
2:57:46
corresponding public property for you
2:57:46
corresponding public property for you for data binding.
2:57:49
And I can also if I go down to uh my
2:57:53
And I can also if I go down to uh my
2:57:53
And I can also if I go down to uh my commands here. So I've got here's the
2:57:55
commands here. So I've got here's the
2:57:55
commands here. So I've got here's the addedit. You see this is private and
2:57:58
addedit. You see this is private and
2:57:58
addedit. You see this is private and it's just called add edit but I've got
2:58:00
it's just called add edit but I've got
2:58:00
it's just called add edit but I've got this relay command decorating it. So
2:58:02
this relay command decorating it. So
2:58:02
this relay command decorating it. So that creates the addedit command that's
2:58:05
that creates the addedit command that's
2:58:05
that creates the addedit command that's public that'll be
2:58:07
public that'll be
2:58:07
public that'll be bound in the uh main page here. So this
2:58:11
bound in the uh main page here. So this
2:58:11
bound in the uh main page here. So this addedit command is created by the source
2:58:17
generator and then within that command
2:58:19
generator and then within that command
2:58:19
generator and then within that command it calls this private method. So when I
2:58:21
it calls this private method. So when I
2:58:21
it calls this private method. So when I hit the button all of this
2:58:24
hit the button all of this
2:58:24
hit the button all of this executes and if I hit delete this is the
2:58:27
executes and if I hit delete this is the
2:58:27
executes and if I hit delete this is the code that gets
2:58:28
code that gets
2:58:28
code that gets executed. And I've got some code to
2:58:31
executed. And I've got some code to
2:58:31
executed. And I've got some code to validate whether the delete button
2:58:32
validate whether the delete button
2:58:32
validate whether the delete button should be
2:58:33
should be
2:58:33
should be enabled.
2:58:36
enabled.
2:58:36
enabled. Anytime that this
2:58:38
Anytime that this
2:58:38
Anytime that this um can delete item is called, it's going
2:58:41
um can delete item is called, it's going
2:58:41
um can delete item is called, it's going to check if there are any selected
2:58:42
to check if there are any selected
2:58:42
to check if there are any selected items. So, I can only hit delete if
2:58:44
items. So, I can only hit delete if
2:58:44
items. So, I can only hit delete if there's an item selected in my
2:58:49
list. Let's take a quick look at the
2:58:51
list. Let's take a quick look at the
2:58:51
list. Let's take a quick look at the item details, view, and view model.
2:58:54
item details, view, and view model.
2:58:54
item details, view, and view model. We'll look at the view first. Uh we'll
2:58:56
We'll look at the view first. Uh we'll
2:58:56
We'll look at the view first. Uh we'll go down to that teaching tip. So, here's
2:58:58
go down to that teaching tip. So, here's
2:58:58
go down to that teaching tip. So, here's the teaching tip and the split button.
2:59:01
the teaching tip and the split button.
2:59:01
the teaching tip and the split button. So the split button has the drop down
2:59:03
So the split button has the drop down
2:59:03
So the split button has the drop down with the two buttons inside of it. And
2:59:06
with the two buttons inside of it. And
2:59:06
with the two buttons inside of it. And to show those, it uses a flyyou with a
2:59:09
to show those, it uses a flyyou with a
2:59:09
to show those, it uses a flyyou with a stack panel and the two buttons inside
2:59:13
stack panel and the two buttons inside
2:59:13
stack panel and the two buttons inside there. And the teaching tip
2:59:18
here. We just data bind
2:59:20
here. We just data bind
2:59:20
here. We just data bind that to the save button and that will
2:59:24
that to the save button and that will
2:59:24
that to the save button and that will attach it to
2:59:30
that. And in the back here we have some
2:59:34
that. And in the back here we have some
2:59:34
that. And in the back here we have some uh little bit of navigation logic so
2:59:36
uh little bit of navigation logic so
2:59:36
uh little bit of navigation logic so that uh when we open up here we're
2:59:39
that uh when we open up here we're
2:59:39
that uh when we open up here we're setting the uh the teaching tip. This is
2:59:41
setting the uh the teaching tip. This is
2:59:41
setting the uh the teaching tip. This is where it's if you had some local
2:59:45
where it's if you had some local
2:59:45
where it's if you had some local settings, you can check whether the view
2:59:47
settings, you can check whether the view
2:59:48
settings, you can check whether the view the user has already viewed that
2:59:49
the user has already viewed that
2:59:49
the user has already viewed that teaching tip and you can set whether
2:59:50
teaching tip and you can set whether
2:59:50
teaching tip and you can set whether it's visible or not. I just have it
2:59:52
it's visible or not. I just have it
2:59:52
it's visible or not. I just have it hardcoded to false so that we'll see it
2:59:54
hardcoded to false so that we'll see it
2:59:54
hardcoded to false so that we'll see it every time that I do this
2:59:57
demo. And the other bit that's important
3:00:00
demo. And the other bit that's important
3:00:00
demo. And the other bit that's important in the code behind here is whenever we
3:00:02
in the code behind here is whenever we
3:00:02
in the code behind here is whenever we navigate to this page, um, we're just
3:00:05
navigate to this page, um, we're just
3:00:05
navigate to this page, um, we're just populating the initial data if there's
3:00:06
populating the initial data if there's
3:00:06
populating the initial data if there's already a an item selected.
3:00:09
already a an item selected.
3:00:09
already a an item selected. So, if there's an item ID, then we're
3:00:12
So, if there's an item ID, then we're
3:00:12
So, if there's an item ID, then we're going to be editing. If there's no item
3:00:13
going to be editing. If there's no item
3:00:14
going to be editing. If there's no item ID, then we know we're adding a new item
3:00:15
ID, then we know we're adding a new item
3:00:15
ID, then we know we're adding a new item and we should have an empty
3:00:20
form. So, that's the basics of some
3:00:23
form. So, that's the basics of some
3:00:23
form. So, that's the basics of some controls. Let's jump back to the slides
3:00:25
controls. Let's jump back to the slides
3:00:25
controls. Let's jump back to the slides and get to another demo
3:00:29
and get to another demo
3:00:29
and get to another demo here. So, the next one will be the uh
3:00:31
here. So, the next one will be the uh
3:00:31
here. So, the next one will be the uh using the Windows community toolkit. So,
3:00:34
using the Windows community toolkit. So,
3:00:34
using the Windows community toolkit. So, there's the there are different uh
3:00:35
there's the there are different uh
3:00:35
there's the there are different uh community toolkits available from
3:00:37
community toolkits available from
3:00:37
community toolkits available from Microsoft that are open source. There's
3:00:39
Microsoft that are open source. There's
3:00:39
Microsoft that are open source. There's the .NET community toolkit I mentioned
3:00:40
the .NET community toolkit I mentioned
3:00:40
the .NET community toolkit I mentioned with the MVVM stuff in it. The Windows
3:00:43
with the MVVM stuff in it. The Windows
3:00:43
with the MVVM stuff in it. The Windows community toolkit. Um there's some
3:00:45
community toolkit. Um there's some
3:00:45
community toolkit. Um there's some Windows specific stuff. Uh you can use
3:00:47
Windows specific stuff. Uh you can use
3:00:47
Windows specific stuff. Uh you can use the things in there for UWP uh Win UI3
3:00:50
the things in there for UWP uh Win UI3
3:00:50
the things in there for UWP uh Win UI3 and also UNO
3:00:52
and also UNO
3:00:52
and also UNO platform. So there are animations,
3:00:55
platform. So there are animations,
3:00:55
platform. So there are animations, triggers, uh behaviors, controls, and
3:00:57
triggers, uh behaviors, controls, and
3:00:57
triggers, uh behaviors, controls, and other helper classes in the toolkit.
3:00:59
other helper classes in the toolkit.
3:01:00
other helper classes in the toolkit. It's open source on GitHub here. Um
3:01:02
It's open source on GitHub here. Um

It's open source on GitHub here. Um there's documentation on Microsoft Learn
3:01:04
there's documentation on Microsoft Learn
3:01:04
there's documentation on Microsoft Learn about the controls and things in the
3:01:06
about the controls and things in the
3:01:06
about the controls and things in the toolkit. And there's a gallery app on
3:01:09
toolkit. And there's a gallery app on
3:01:09
toolkit. And there's a gallery app on the Microsoft Store. We'll take a look
3:01:11
the Microsoft Store. We'll take a look
3:01:11
the Microsoft Store. We'll take a look at that quick. I've got that open here.
3:01:15
at that quick. I've got that open here.
3:01:15
at that quick. I've got that open here. So, within the gallery, you can explore
3:01:16
So, within the gallery, you can explore
3:01:16
So, within the gallery, you can explore everything in the toolkit and see things
3:01:19
everything in the toolkit and see things
3:01:19
everything in the toolkit and see things working in the UI to see how they look.
3:01:22
working in the UI to see how they look.
3:01:22
working in the UI to see how they look. If I go to go to items
3:01:25
If I go to go to items
3:01:25
If I go to go to items view, so it shows you what the items
3:01:28
view, so it shows you what the items
3:01:28
view, so it shows you what the items view looks like. It's running live here
3:01:30
view looks like. It's running live here
3:01:30
view looks like. It's running live here in the app.
3:01:34
So if I expand the source code, it shows
3:01:36
So if I expand the source code, it shows
3:01:36
So if I expand the source code, it shows me the code that was used to create
3:01:38
me the code that was used to create
3:01:38
me the code that was used to create that. So you can copy and paste from
3:01:40
that. So you can copy and paste from
3:01:40
that. So you can copy and paste from here to get started quickly. Shows you
3:01:43
here to get started quickly. Shows you
3:01:43
here to get started quickly. Shows you the ZAML code for that and also the C
3:01:47
the ZAML code for that and also the C
3:01:47
the ZAML code for that and also the C for any stuff in the code
3:01:49
for any stuff in the code
3:01:49
for any stuff in the code behind. And with some of the samples in
3:01:51
behind. And with some of the samples in
3:01:51
behind. And with some of the samples in the toolkit app, you can change some
3:01:55
the toolkit app, you can change some
3:01:55
the toolkit app, you can change some properties to see how it will look in uh
3:01:57
properties to see how it will look in uh
3:01:57
properties to see how it will look in uh different layouts. So it's got three
3:01:59
different layouts. So it's got three
3:01:59
different layouts. So it's got three different layouts that you can pick from
3:02:00
different layouts that you can pick from
3:02:00
different layouts that you can pick from here.
3:02:02
here.
3:02:02
here. You can change the number
3:02:03
You can change the number
3:02:03
You can change the number of amount of space between them and
3:02:07
of amount of space between them and
3:02:07
of amount of space between them and space these out a little
3:02:15
farther. And we can change the selection
3:02:17
farther. And we can change the selection
3:02:17
farther. And we can change the selection mode for this item. So right now it's
3:02:20
mode for this item. So right now it's
3:02:20
mode for this item. So right now it's multiple. I can select multiple items.
3:02:23
multiple. I can select multiple items.
3:02:23
multiple. I can select multiple items. You can change that to
3:02:25
You can change that to
3:02:25
You can change that to single. So check boxes are gone. You
3:02:27
single. So check boxes are gone. You
3:02:28
single. So check boxes are gone. You just select one at a time.
3:02:34
So, let's take a look at um a sample app
3:02:36
So, let's take a look at um a sample app
3:02:36
So, let's take a look at um a sample app that's got this in
3:02:42
it. So, I've got a community toolkit
3:02:45
it. So, I've got a community toolkit
3:02:45
it. So, I've got a community toolkit solution here. And you'll notice for
3:02:47
solution here. And you'll notice for
3:02:47
solution here. And you'll notice for some of these solutions, I have both an
3:02:49
some of these solutions, I have both an
3:02:49
some of these solutions, I have both an a solution and a solution x slmx. Some
3:02:53
a solution and a solution x slmx. Some
3:02:53
a solution and a solution x slmx. Some people are calling these slinks files.
3:02:56
people are calling these slinks files.
3:02:56
people are calling these slinks files. Uh it's a new solution format that's
3:02:58
Uh it's a new solution format that's
3:02:58
Uh it's a new solution format that's currently in preview. Uh it works with
3:03:00
currently in preview. Uh it works with
3:03:00
currently in preview. Uh it works with the Visual Studio 2022 uh preview
3:03:03
the Visual Studio 2022 uh preview
3:03:03
the Visual Studio 2022 uh preview version. And these are a lot nicer to
3:03:06
version. And these are a lot nicer to
3:03:06
version. And these are a lot nicer to look at if you ever opened a solution
3:03:07
look at if you ever opened a solution
3:03:08
look at if you ever opened a solution file and you've seen all the goods in
3:03:09
file and you've seen all the goods in
3:03:09
file and you've seen all the goods in there. The solution X
3:03:11
there. The solution X
3:03:11
there. The solution X files have no goods and they're they're
3:03:14
files have no goods and they're they're
3:03:14
files have no goods and they're they're much simpler to look at. We won't demo
3:03:16
much simpler to look at. We won't demo
3:03:16
much simpler to look at. We won't demo that here, but you should go check it
3:03:20
out. So here I have a hardware supplies
3:03:23
out. So here I have a hardware supplies
3:03:23
out. So here I have a hardware supplies app. Let's run it first to see what this
3:03:25
app. Let's run it first to see what this
3:03:25
app. Let's run it first to see what this looks
3:03:27
looks
3:03:27
looks like. Call it hardware supplies, but
3:03:29
like. Call it hardware supplies, but
3:03:29
like. Call it hardware supplies, but it's uh got a list of hardware items and
3:03:32
it's uh got a list of hardware items and
3:03:32
it's uh got a list of hardware items and then another color picker control here.
3:03:35
then another color picker control here.
3:03:36
then another color picker control here. So, you'll see I've got a data
3:03:38
So, you'll see I've got a data
3:03:38
So, you'll see I've got a data grid with some hardware items in it. And
3:03:42
grid with some hardware items in it. And
3:03:42
grid with some hardware items in it. And this control, I can resize the columns
3:03:44
this control, I can resize the columns
3:03:44
this control, I can resize the columns nicely, like your basic data grid
3:03:46
nicely, like your basic data grid
3:03:46
nicely, like your basic data grid functionality. And you'll see I've also
3:03:48
functionality. And you'll see I've also
3:03:48
functionality. And you'll see I've also got a little shadow around here. And
3:03:51
got a little shadow around here. And
3:03:51
got a little shadow around here. And I've got some text here with a shadow on
3:03:54
I've got some text here with a shadow on
3:03:54
I've got some text here with a shadow on it. And my color picker control. I'm
3:03:57
it. And my color picker control. I'm
3:03:57
it. And my color picker control. I'm using data binding to bind to this
3:03:59
using data binding to bind to this
3:03:59
using data binding to bind to this shadow color. So if I
3:04:01
shadow color. So if I
3:04:01
shadow color. So if I change the color that I've picked here,
3:04:04
change the color that I've picked here,
3:04:04
change the color that I've picked here, it changes my shadows in real
3:04:10
time. Anything I change there changes.
3:04:13
time. Anything I change there changes.
3:04:13
time. Anything I change there changes. You can change the
3:04:15
You can change the
3:04:15
You can change the uh type of selection.
3:04:23
And that's uh one of the controls in the
3:04:25
And that's uh one of the controls in the
3:04:25
And that's uh one of the controls in the community toolkit. Let's take a look at
3:04:26
community toolkit. Let's take a look at
3:04:26
community toolkit. Let's take a look at um the code for
3:04:30
this. So in our main
3:04:39
window, there we
3:04:41
window, there we
3:04:41
window, there we go. So I've got the Micah backdrop on
3:04:43
go. So I've got the Micah backdrop on
3:04:43
go. So I've got the Micah backdrop on here as
3:04:44
here as
3:04:45
here as well. And for the drop
3:04:47
well. And for the drop
3:04:47
well. And for the drop shadow using an attached drop shadow
3:04:50
shadow using an attached drop shadow
3:04:50
shadow using an attached drop shadow from the toolkit. I named it common
3:04:54
from the toolkit. I named it common
3:04:54
from the toolkit. I named it common shadow and I'm binding that to the uh
3:04:57
shadow and I'm binding that to the uh
3:04:57
shadow and I'm binding that to the uh the color
3:05:01
picker and setting the path to color. So
3:05:04
picker and setting the path to color. So
3:05:04
picker and setting the path to color. So that's telling it to pick up the color
3:05:06
that's telling it to pick up the color
3:05:06
that's telling it to pick up the color property from the color picker and use
3:05:08
property from the color picker and use
3:05:08
property from the color picker and use that for the shadow color.
3:05:12
And then down here, this header content
3:05:14
And then down here, this header content
3:05:14
And then down here, this header content control, that's the uh that was the
3:05:16
control, that's the uh that was the
3:05:16
control, that's the uh that was the header at the
3:05:20
top. And I've got a drop shadow panel,
3:05:23
top. And I've got a drop shadow panel,
3:05:23
top. And I've got a drop shadow panel, which is also binding to the color
3:05:27
which is also binding to the color
3:05:27
which is also binding to the color picker to pick up that shadow
3:05:31
color. And this is my data grid. All I'm
3:05:34
color. And this is my data grid. All I'm
3:05:34
color. And this is my data grid. All I'm doing here is binding the item source to
3:05:37
doing here is binding the item source to
3:05:37
doing here is binding the item source to a list of hardware items that are
3:05:38
a list of hardware items that are
3:05:38
a list of hardware items that are hardcoded in the the back
3:05:41
hardcoded in the the back
3:05:41
hardcoded in the the back go behind
3:05:44
here. It's got some code to add a bunch
3:05:47
here. It's got some code to add a bunch
3:05:47
here. It's got some code to add a bunch of items to that
3:05:52
list. And then finally, got a grid at
3:05:55
list. And then finally, got a grid at
3:05:55
list. And then finally, got a grid at the bottom that
3:05:57
the bottom that
3:05:57
the bottom that contains the uh text block for the uh
3:06:02
contains the uh text block for the uh
3:06:02
contains the uh text block for the uh the final shadow says I love hardware
3:06:04
the final shadow says I love hardware
3:06:04
the final shadow says I love hardware and all related
3:06:06
and all related
3:06:06
and all related supplies. And I set the uh
3:06:08
supplies. And I set the uh
3:06:08
supplies. And I set the uh effects.shadow shadow property to the
3:06:10
effects.shadow shadow property to the
3:06:10
effects.shadow shadow property to the common shadow that's up in the resource
3:06:12
common shadow that's up in the resource
3:06:12
common shadow that's up in the resource at the
3:06:16
top. And finally, the color picker. It's
3:06:19
top. And finally, the color picker. It's
3:06:19
top. And finally, the color picker. It's got a lot of different properties you
3:06:20
got a lot of different properties you
3:06:20
got a lot of different properties you can set. So, I'm setting the spectrum
3:06:23
can set. So, I'm setting the spectrum
3:06:23
can set. So, I'm setting the spectrum shape to a
3:06:26
shape to a
3:06:26
shape to a ring. You can enable and disable some
3:06:28
ring. You can enable and disable some
3:06:28
ring. You can enable and disable some different things about whether you want
3:06:29
different things about whether you want
3:06:29
different things about whether you want to have the different sliders and other
3:06:32
to have the different sliders and other
3:06:32
to have the different sliders and other picking elements available.
3:06:34
picking elements available.
3:06:34
picking elements available. And then I'm setting the default color
3:06:36
And then I'm setting the default color
3:06:36
And then I'm setting the default color when it launches to be my system accent
3:06:39
when it launches to be my system accent
3:06:39
when it launches to be my system accent color. So whatever the user's uh system
3:06:41
color. So whatever the user's uh system
3:06:41
color. So whatever the user's uh system accent color is in Windows, that'll be
3:06:43
accent color is in Windows, that'll be
3:06:43
accent color is in Windows, that'll be the the color of the shadows when you
3:06:45
the the color of the shadows when you
3:06:45
the the color of the shadows when you first
3:06:49
launch. And in the code behind, like I
3:06:52
launch. And in the code behind, like I
3:06:52
launch. And in the code behind, like I said, there's just the hardware items
3:06:54
said, there's just the hardware items
3:06:54
said, there's just the hardware items and then we've got the code to set the
3:06:56
and then we've got the code to set the
3:06:56
and then we've got the code to set the uh title bar up.
3:07:02
All right, let's move on to another demo
3:07:06
All right, let's move on to another demo
3:07:06
All right, let's move on to another demo here. We should have time to get to a
3:07:07
here. We should have time to get to a
3:07:07
here. We should have time to get to a couple
3:07:11
more
3:07:13
more
3:07:13
more notifications. So, the uh notifications
3:07:16
notifications. So, the uh notifications
3:07:16
notifications. So, the uh notifications API in the Windows app SDK lets you use
3:07:18
API in the Windows app SDK lets you use
3:07:18
API in the Windows app SDK lets you use uh toast notifications in Windows. And
3:07:21
uh toast notifications in Windows. And
3:07:21
uh toast notifications in Windows. And there's a couple different types that we
3:07:22
there's a couple different types that we
3:07:22
there's a couple different types that we can create here. Let's uh pop open that
3:07:26
can create here. Let's uh pop open that
3:07:26
can create here. Let's uh pop open that demo project.
3:07:32
And most of these demos are adapted from
3:07:34
And most of these demos are adapted from
3:07:34
And most of these demos are adapted from samples in my book. I've got that
3:07:36
samples in my book. I've got that
3:07:36
samples in my book. I've got that chapter on notifications that I pulled
3:07:38
chapter on notifications that I pulled
3:07:38
chapter on notifications that I pulled this demo
3:07:42
from. So, we've got the media collection
3:07:45
from. So, we've got the media collection
3:07:45
from. So, we've got the media collection app again, but it's been enhanced a
3:07:46
app again, but it's been enhanced a
3:07:46
app again, but it's been enhanced a little
3:07:48
little
3:07:48
little bit. Let's launch
3:07:52
bit. Let's launch
3:07:52
bit. Let's launch this. We've got a couple of extra
3:07:54
this. We've got a couple of extra
3:07:54
this. We've got a couple of extra buttons at the bottom when this opens
3:07:56
buttons at the bottom when this opens
3:07:56
buttons at the bottom when this opens up.
3:08:02
So, we don't have the
3:08:04
So, we don't have the
3:08:04
So, we don't have the uh special title bar here. It's got the
3:08:06
uh special title bar here. It's got the
3:08:06
uh special title bar here. It's got the standard title bar that you get out of
3:08:08
standard title bar that you get out of
3:08:08
standard title bar that you get out of the box, but we do have some new buttons
3:08:10
the box, but we do have some new buttons
3:08:10
the box, but we do have some new buttons down here for notifications. So, we can
3:08:13
down here for notifications. So, we can
3:08:13
down here for notifications. So, we can send a notification or we can send a
3:08:15
send a notification or we can send a
3:08:15
send a notification or we can send a notification that will also have a text
3:08:18
notification that will also have a text
3:08:18
notification that will also have a text box for a reply. So, let's try the
3:08:20
box for a reply. So, let's try the
3:08:20
box for a reply. So, let's try the initial regular notification.
3:08:24
initial regular notification.
3:08:24
initial regular notification. You can see pops up a toast. And if your
3:08:28
You can see pops up a toast. And if your
3:08:28
You can see pops up a toast. And if your app is behind something, I can click
3:08:30
app is behind something, I can click
3:08:30
app is behind something, I can click open app and it brings it to the
3:08:32
open app and it brings it to the
3:08:32
open app and it brings it to the front and I get a popup saying we
3:08:35
front and I get a popup saying we
3:08:35
front and I get a popup saying we received this
3:08:37
received this
3:08:37
received this notification to open the
3:08:39
notification to open the
3:08:39
notification to open the app. We'll hit okay there. I'm also
3:08:42
app. We'll hit okay there. I'm also
3:08:42
app. We'll hit okay there. I'm also using a status bar to show the uh
3:08:44
using a status bar to show the uh
3:08:44
using a status bar to show the uh current
3:08:45
current
3:08:45
current status. Last thing that happened was a
3:08:47
status. Last thing that happened was a
3:08:47
status. Last thing that happened was a notification was
3:08:48
notification was
3:08:48
notification was received. The next notification we'll
3:08:51
received. The next notification we'll
3:08:51
received. The next notification we'll send will have that text box.
3:08:54
send will have that text box.
3:08:54
send will have that text box. Here's our toast. And now I can enter a
3:09:08
reply. So I've received that. If your
3:09:11
reply. So I've received that. If your
3:09:11
reply. So I've received that. If your app was in the back, it would have
3:09:12
app was in the back, it would have
3:09:12
app was in the back, it would have brought it to the front again, but our
3:09:13
brought it to the front again, but our
3:09:13
brought it to the front again, but our app was at the
3:09:15
app was at the
3:09:15
app was at the front. Here's the uh reply. It says
3:09:18
front. Here's the uh reply. It says
3:09:18
front. Here's the uh reply. It says input received was hello C# TV.
3:09:22
input received was hello C# TV.
3:09:22
input received was hello C# TV. and we click okay
3:09:24
and we click okay
3:09:24
and we click okay there. So let's take a quick look at how
3:09:27
there. So let's take a quick look at how
3:09:27
there. So let's take a quick look at how that code is implemented. But um there's
3:09:30
that code is implemented. But um there's
3:09:30
that code is implemented. But um there's a link in my uh list of links in GitHub
3:09:34
a link in my uh list of links in GitHub
3:09:34
a link in my uh list of links in GitHub that points you to the Microsoft learn
3:09:36
that points you to the Microsoft learn
3:09:36
that points you to the Microsoft learn article that could walk you through all
3:09:37

article that could walk you through all of this step by
3:09:39
of this step by
3:09:39
of this step by step. So we have a few extra classes
3:09:42
step. So we have a few extra classes
3:09:42
step. So we have a few extra classes here. Let's go to the helpers. We've got
3:09:46
here. Let's go to the helpers. We've got
3:09:46
here. Let's go to the helpers. We've got toast with text and toast with avatar.
3:09:48
toast with text and toast with avatar.
3:09:48
toast with text and toast with avatar. These are two different uh they're like
3:09:50
These are two different uh they're like
3:09:50
These are two different uh they're like templates for creating your
3:09:54
toast. So here when I send the
3:09:58
toast. So here when I send the
3:09:58
toast. So here when I send the toast I'm adding arguments
3:10:02
toast I'm adding arguments
3:10:02
toast I'm adding arguments for the different scenarios I have. Um
3:10:05
for the different scenarios I have. Um
3:10:05
for the different scenarios I have. Um I'm telling
3:10:07
I'm telling
3:10:07
I'm telling it to use this
3:10:10
it to use this
3:10:10
it to use this icon cropping the image to a circle when
3:10:13
icon cropping the image to a circle when
3:10:13
icon cropping the image to a circle when it appears on the toast. Here's the text
3:10:17
it appears on the toast. Here's the text
3:10:17
it appears on the toast. Here's the text that will appear on the
3:10:19
that will appear on the
3:10:19
that will appear on the toast. And this is the uh text box.
3:10:22
toast. And this is the uh text box.
3:10:22
toast. And this is the uh text box. We're adding a text box to it. And this
3:10:25
We're adding a text box to it. And this
3:10:26
We're adding a text box to it. And this is the
3:10:27
is the
3:10:27
is the pre-populated text that will show in the
3:10:29
pre-populated text that will show in the
3:10:29
pre-populated text that will show in the text box for the
3:10:31
text box for the
3:10:31
text box for the user. And there's a button. So the
3:10:33
user. And there's a button. So the
3:10:33
user. And there's a button. So the button on the toast says reply. And the
3:10:37
button on the toast says reply. And the
3:10:37
button on the toast says reply. And the action is reply. And that's what we got
3:10:38
action is reply. And that's what we got
3:10:38
action is reply. And that's what we got back in the message that appeared on the
3:10:41
back in the message that appeared on the
3:10:41
back in the message that appeared on the screen.
3:10:43
screen.
3:10:44
screen. If we look at the other one, the one
3:10:45
If we look at the other one, the one
3:10:45
If we look at the other one, the one without the text box, it looks pretty
3:10:47
without the text box, it looks pretty
3:10:47
without the text box, it looks pretty similar, but we don't
3:10:49
similar, but we don't
3:10:49
similar, but we don't have we just go from text to button. We
3:10:51
have we just go from text to button. We
3:10:52
have we just go from text to button. We don't have the text box in this
3:10:57
one. And then we've got a notification
3:11:03
manager. This is where we register to
3:11:06
manager. This is where we register to
3:11:06
manager. This is where we register to receive notifications.
3:11:12
So in the initialize
3:11:14
So in the initialize
3:11:15
So in the initialize here, we're setting up an event handler
3:11:17
here, we're setting up an event handler
3:11:17
here, we're setting up an event handler to find out when notifications are
3:11:20
to find out when notifications are
3:11:20
to find out when notifications are invoked and calling this register on the
3:11:23
invoked and calling this register on the
3:11:23
invoked and calling this register on the the
3:11:24
the
3:11:24
the handler. When messages are received,
3:11:27
handler. When messages are received,
3:11:27
handler. When messages are received, we're going to process them
3:11:30
we're going to process them
3:11:30
we're going to process them here. Send the notification out to
3:11:33
here. Send the notification out to
3:11:33
here. Send the notification out to Windows. And then this is this
3:11:36
Windows. And then this is this
3:11:36
Windows. And then this is this notification
3:11:40
shared. These are all the updates that
3:11:42
shared. These are all the updates that
3:11:42
shared. These are all the updates that we received in that status bar. So the
3:11:45
we received in that status bar. So the
3:11:45
we received in that status bar. So the status bar in the app gets updated based
3:11:46
status bar in the app gets updated based
3:11:46
status bar in the app gets updated based on which one of these we've called from
3:11:48
on which one of these we've called from
3:11:48
on which one of these we've called from the manager
3:11:51
class. And
3:11:54
class. And
3:11:54
class. And finally notification
3:11:57
finally notification
3:11:57
finally notification received. If there's any issues, we just
3:12:01
received. If there's any issues, we just
3:12:01
received. If there's any issues, we just pop up a message saying there was some
3:12:03
pop up a message saying there was some
3:12:03
pop up a message saying there was some uh
3:12:05
uh
3:12:05
uh unrecognized message that was
3:12:10
received. And like I said, this is all
3:12:12
received. And like I said, this is all
3:12:12
received. And like I said, this is all out on learn. Uh this is my speaking
3:12:15
out on learn. Uh this is my speaking
3:12:16
out on learn. Uh this is my speaking repo, but this is the page within this
3:12:19
repo, but this is the page within this
3:12:19
repo, but this is the page within this conferences stuff. So I've got all the
3:12:21
conferences stuff. So I've got all the
3:12:21
conferences stuff. So I've got all the links for all this. And if you go to the
3:12:26
links for all this. And if you go to the
3:12:26
links for all this. And if you go to the notifications here, Windows App SDK app
3:12:32
notifications. So, this overview gives
3:12:34
notifications. So, this overview gives
3:12:34
notifications. So, this overview gives you a little info, but then there's a a
3:12:36
you a little info, but then there's a a
3:12:36
you a little info, but then there's a a quick start that walks you through all
3:12:39
quick start that walks you through all
3:12:39
quick start that walks you through all of this on how to set up the uh
3:12:42
of this on how to set up the uh
3:12:42
of this on how to set up the uh notifications for your own
3:12:49
apps. All right. Next, we don't probably
3:12:53
apps. All right. Next, we don't probably
3:12:53
apps. All right. Next, we don't probably have time to go through all the interop
3:12:55
have time to go through all the interop
3:12:55
have time to go through all the interop uh demos, but there are a couple
3:12:57
uh demos, but there are a couple
3:12:57
uh demos, but there are a couple different ways that you can do
3:13:00
different ways that you can do
3:13:00
different ways that you can do interop. So, there's ZAML islands. So,
3:13:03
interop. So, there's ZAML islands. So,
3:13:03
interop. So, there's ZAML islands. So, this was added in Windows App SDK 1.4
3:13:06
this was added in Windows App SDK 1.4
3:13:07
this was added in Windows App SDK 1.4 four. And uh right now they're still
3:13:09
four. And uh right now they're still
3:13:09
four. And uh right now they're still working on enhancing this, but you can
3:13:11
working on enhancing this, but you can
3:13:11
working on enhancing this, but you can only use the ZAML islands to uh
3:13:15
only use the ZAML islands to uh
3:13:15
only use the ZAML islands to uh show uh Windows app SDK Win UI stuff
3:13:18
show uh Windows app SDK Win UI stuff
3:13:18
show uh Windows app SDK Win UI stuff within a C++ app. So you can't use this
3:13:21
within a C++ app. So you can't use this
3:13:21
within a C++ app. So you can't use this in other uh Windforms or WPF apps yet.
3:13:25
in other uh Windforms or WPF apps yet.
3:13:25
in other uh Windforms or WPF apps yet. Um but there there's a sample up on
3:13:27
Um but there there's a sample up on
3:13:27
Um but there there's a sample up on GitHub from the team that shows you how
3:13:29
GitHub from the team that shows you how
3:13:29
GitHub from the team that shows you how to implement this in a C++ app. And I do
3:13:31
to implement this in a C++ app. And I do
3:13:31
to implement this in a C++ app. And I do also have the code in my repo.
3:13:37
And we don't have time to walk through
3:13:38
And we don't have time to walk through
3:13:38
And we don't have time to walk through the code, but I can run this quickly and
3:13:40
the code, but I can run this quickly and
3:13:40
the code, but I can run this quickly and show you how it
3:13:49
works. Let's run this. So, this is a a
3:13:52
works. Let's run this. So, this is a a
3:13:52
works. Let's run this. So, this is a a C++ project and it's within here it's
3:13:56
C++ project and it's within here it's
3:13:56
C++ project and it's within here it's got a couple of Win32 buttons. These are
3:13:58
got a couple of Win32 buttons. These are
3:13:58
got a couple of Win32 buttons. These are C++
3:14:00
C++
3:14:00
C++ buttons. And then within there, it's
3:14:02
buttons. And then within there, it's
3:14:02
buttons. And then within there, it's also got some Win UI content. So
3:14:05
also got some Win UI content. So
3:14:05
also got some Win UI content. So everything from this toolbar down is all
3:14:09
everything from this toolbar down is all
3:14:09
everything from this toolbar down is all WinUI content. So we've got a web view
3:14:11
WinUI content. So we've got a web view
3:14:11
WinUI content. So we've got a web view control that's when UUI. It's got some
3:14:14
control that's when UUI. It's got some
3:14:14
control that's when UUI. It's got some uh WinUI
3:14:17
uh WinUI
3:14:17
uh WinUI buttons, text
3:14:20
buttons, text
3:14:20
buttons, text box. So all this is embedded within the
3:14:23
box. So all this is embedded within the
3:14:23
box. So all this is embedded within the C++
3:14:29
app. And the other way that you can do
3:14:32
app. And the other way that you can do
3:14:32
app. And the other way that you can do interop, let's go back to PowerPoint.
3:14:35
interop, let's go back to PowerPoint.
3:14:35
interop, let's go back to PowerPoint. So you can use the web view control to
3:14:37
So you can use the web view control to
3:14:37
So you can use the web view control to embed uh web content within your WinUI
3:14:41
embed uh web content within your WinUI
3:14:41
embed uh web content within your WinUI apps. And I have a sample that embeds a
3:14:44
apps. And I have a sample that embeds a
3:14:44
apps. And I have a sample that embeds a Blazer app inside there. So let's run
3:14:48
Blazer app inside there. So let's run
3:14:48
Blazer app inside there. So let's run that quickly just to show you what that
3:14:50
that quickly just to show you what that
3:14:50
that quickly just to show you what that looks
3:14:51
looks
3:14:51
looks like. So I've got two projects in here.
3:14:54
like. So I've got two projects in here.
3:14:54
like. So I've got two projects in here. I've got a Blazer project that uses web
3:14:57
I've got a Blazer project that uses web
3:14:57
I've got a Blazer project that uses web assembly and I have that running out on
3:14:59
assembly and I have that running out on
3:14:59
assembly and I have that running out on the web so we don't have to kick that
3:15:00
the web so we don't have to kick that
3:15:00
the web so we don't have to kick that off here. This is my WinUI project. And
3:15:03
off here. This is my WinUI project. And
3:15:03
off here. This is my WinUI project. And this will just load up our Blazer
3:15:06
this will just load up our Blazer
3:15:06
this will just load up our Blazer content from the
3:15:09
web. Let's run
3:15:14
this. And when this opens, it's just
3:15:17
this. And when this opens, it's just
3:15:17
this. And when this opens, it's just going to be a WinUI shell with your
3:15:19
going to be a WinUI shell with your
3:15:19
going to be a WinUI shell with your basic uh Blazer Hello World app. This is
3:15:23
basic uh Blazer Hello World app. This is
3:15:23
basic uh Blazer Hello World app. This is what you get when you create a new
3:15:25
what you get when you create a new
3:15:25
what you get when you create a new Blazer project. Most of you are probably
3:15:27
Blazer project. Most of you are probably
3:15:27
Blazer project. Most of you are probably familiar with this.
3:15:29
familiar with this.
3:15:29
familiar with this. This is all running in the
3:15:32
This is all running in the
3:15:32
This is all running in the web. Take a look at this code
3:15:37
quickly. Crl
3:15:40
quickly. Crl
3:15:40
quickly. Crl C. So the only thing in here is the web
3:15:42
C. So the only thing in here is the web
3:15:42
C. So the only thing in here is the web view control. And I'm just pointing it
3:15:44
view control. And I'm just pointing it
3:15:44
view control. And I'm just pointing it out to where my Blazer app is running
3:15:48
online. Nothing else here. Nothing in
3:15:50
online. Nothing else here. Nothing in
3:15:50
online. Nothing else here. Nothing in the code behind. It's just loading up
3:15:52
the code behind. It's just loading up
3:15:52
the code behind. It's just loading up the Blazer app.
3:15:57
Let's jump back to the slides and see if
3:15:59
Let's jump back to the slides and see if
3:15:59
Let's jump back to the slides and see if we can get through a couple more quick
3:16:01
we can get through a couple more quick
3:16:01
we can get through a couple more quick things. Uh deployment options. So there
3:16:05
things. Uh deployment options. So there
3:16:05
things. Uh deployment options. So there are different ways that you can package
3:16:06
are different ways that you can package
3:16:06
are different ways that you can package your app, your WinUI apps. Um you can
3:16:08
your app, your WinUI apps. Um you can
3:16:08
your app, your WinUI apps. Um you can make them framework dependent or
3:16:11
make them framework dependent or
3:16:12
make them framework dependent or self-contained. So framework dependent
3:16:13
self-contained. So framework dependent
3:16:13
self-contained. So framework dependent apps depend on the Windows app SDK
3:16:16
apps depend on the Windows app SDK
3:16:16
apps depend on the Windows app SDK runtime being on the client machine.
3:16:19
runtime being on the client machine.
3:16:19
runtime being on the client machine. um and self-contained apps you when you
3:16:21
um and self-contained apps you when you
3:16:21
um and self-contained apps you when you deploy your app you're deploying the
3:16:23
deploy your app you're deploying the
3:16:23
deploy your app you're deploying the Windows app SDK runtime with your app.
3:16:25
Windows app SDK runtime with your app.
3:16:25
Windows app SDK runtime with your app. So you have more control over uh the
3:16:28
So you have more control over uh the
3:16:28
So you have more control over uh the size of or you have more control over
3:16:30
size of or you have more control over
3:16:30
size of or you have more control over the versioning of your package that your
3:16:33
the versioning of your package that your
3:16:33
the versioning of your package that your app has. Uh but the the size is going to
3:16:35
app has. Uh but the the size is going to
3:16:35
app has. Uh but the the size is going to be obviously much bigger when you're
3:16:37
be obviously much bigger when you're
3:16:37
be obviously much bigger when you're deploying the uh whole runtime along
3:16:39
deploying the uh whole runtime along
3:16:39
deploying the uh whole runtime along with your
3:16:40
with your
3:16:40
with your app. Uh you can deploy out to the
3:16:42
app. Uh you can deploy out to the
3:16:42
app. Uh you can deploy out to the Microsoft store. Uh you can deploy
3:16:46
Microsoft store. Uh you can deploy
3:16:46
Microsoft store. Uh you can deploy through winget. So up on the wingget
3:16:48
through winget. So up on the wingget
3:16:48
through winget. So up on the wingget repository, you can put your app up
3:16:50
repository, you can put your app up
3:16:50
repository, you can put your app up there. Uh there's ways that you can
3:16:52
there. Uh there's ways that you can
3:16:52
there. Uh there's ways that you can sideloadad. Um I've got a link here for
3:16:55
sideloadad. Um I've got a link here for
3:16:55
sideloadad. Um I've got a link here for instructions of how Net Maui Windows
3:16:58
instructions of how Net Maui Windows
3:16:58
instructions of how Net Maui Windows apps can be sideloaded and that same
3:17:01
apps can be sideloaded and that same
3:17:01
apps can be sideloaded and that same process works for any WinUI
3:17:03
process works for any WinUI
3:17:03
process works for any WinUI app. And there are also thirdparty
3:17:06
app. And there are also thirdparty
3:17:06
app. And there are also thirdparty installers. So install shield, uh
3:17:09
installers. So install shield, uh
3:17:09
installers. So install shield, uh advanced installer, all those things can
3:17:10
advanced installer, all those things can
3:17:10
advanced installer, all those things can work with your WinUI apps.
3:17:16
And we won't be able to get into Uno
3:17:19
And we won't be able to get into Uno
3:17:19
And we won't be able to get into Uno platform but uh I can explain quickly.
3:17:22
platform but uh I can explain quickly.
3:17:22
platform but uh I can explain quickly. So UNO platform is um multiplatform
3:17:26
So UNO platform is um multiplatform
3:17:26
So UNO platform is um multiplatform solution kind of like Net Maui but they
3:17:28
solution kind of like Net Maui but they
3:17:28
solution kind of like Net Maui but they can also run on Linux and on the web
3:17:31
can also run on Linux and on the web
3:17:31
can also run on Linux and on the web with web assembly. So you can create a
3:17:33
with web assembly. So you can create a
3:17:33
with web assembly. So you can create a single codebase that runs on iOS,
3:17:35
single codebase that runs on iOS,
3:17:35
single codebase that runs on iOS, Android, Windows, Linux uh just about
3:17:38
Android, Windows, Linux uh just about
3:17:38
Android, Windows, Linux uh just about any platform all from the single uh
3:17:40
any platform all from the single uh
3:17:40
any platform all from the single uh codebase. And the ZAML used in UNO
3:17:43
codebase. And the ZAML used in UNO
3:17:43
codebase. And the ZAML used in UNO platform is WinUI ZAML. uh in my book in
3:17:46
platform is WinUI ZAML. uh in my book in
3:17:46
platform is WinUI ZAML. uh in my book in the one chapter where I show an UNO
3:17:48
the one chapter where I show an UNO
3:17:48
the one chapter where I show an UNO platform demo. I just take my Win UI
3:17:50
platform demo. I just take my Win UI
3:17:50
platform demo. I just take my Win UI code and I copy and paste it into an Uno
3:17:53
code and I copy and paste it into an Uno
3:17:53
code and I copy and paste it into an Uno solution and it's the exact same code
3:17:55
solution and it's the exact same code
3:17:55
solution and it's the exact same code that I can now run on any
3:17:58
that I can now run on any
3:17:58
that I can now run on any platform. And the latest releases of Uno
3:18:01
platform. And the latest releases of Uno
3:18:01
platform. And the latest releases of Uno also have a hot design which lets you um
3:18:04
also have a hot design which lets you um
3:18:04
also have a hot design which lets you um drag and drop design your apps at
3:18:07
drag and drop design your apps at
3:18:07
drag and drop design your apps at runtime. So while you're running your
3:18:09
runtime. So while you're running your
3:18:09
runtime. So while you're running your app, you can open up this designer and
3:18:11
app, you can open up this designer and
3:18:11
app, you can open up this designer and make changes and it'll save those
3:18:12
make changes and it'll save those
3:18:12
make changes and it'll save those changes back to your project. and see
3:18:15
changes back to your project. and see
3:18:15
changes back to your project. and see them uh at
3:18:20
runtime and we're not doing the demo of
3:18:23
runtime and we're not doing the demo of
3:18:23
runtime and we're not doing the demo of Uno. Uh final thing here, the WinUI road
3:18:27
Uno. Uh final thing here, the WinUI road
3:18:27
Uno. Uh final thing here, the WinUI road map. So, Windows App SDK 1.7 was just
3:18:30
map. So, Windows App SDK 1.7 was just
3:18:30
map. So, Windows App SDK 1.7 was just released and 1.8 is up next. Uh they
3:18:34
released and 1.8 is up next. Uh they
3:18:34
released and 1.8 is up next. Uh they just released the first experimental
3:18:36
just released the first experimental
3:18:36
just released the first experimental release of 1.8.
3:18:39
release of 1.8.
3:18:39
release of 1.8. Uh the new things in 1.7 were a lot of
3:18:42
Uh the new things in 1.7 were a lot of
3:18:42
Uh the new things in 1.7 were a lot of things that people had in UWP that were
3:18:45
things that people had in UWP that were
3:18:45
things that people had in UWP that were missing. Um background task manager is
3:18:48
missing. Um background task manager is
3:18:48
missing. Um background task manager is now available in WinUI. Uh camera
3:18:50
now available in WinUI. Uh camera
3:18:50
now available in WinUI. Uh camera capture UI so you can use the camera in
3:18:53
capture UI so you can use the camera in
3:18:53
capture UI so you can use the camera in your PC to capture images. Uh the new
3:18:56
your PC to capture images. Uh the new
3:18:56
your PC to capture images. Uh the new title bar we saw and the OOTH manager so
3:18:59
title bar we saw and the OOTH manager so
3:18:59
title bar we saw and the OOTH manager so you can do OOTH authentication in your
3:19:02
you can do OOTH authentication in your
3:19:02
you can do OOTH authentication in your apps. And they're working on a ZAML
3:19:05
apps. And they're working on a ZAML
3:19:05
apps. And they're working on a ZAML designer. Right now there's no UI
3:19:09
designer. Right now there's no UI
3:19:09
designer. Right now there's no UI designer for WinUI apps. You have to
3:19:11
designer for WinUI apps. You have to
3:19:11
designer for WinUI apps. You have to handcode all your ZAML. Uh but they have
3:19:13
handcode all your ZAML. Uh but they have
3:19:13
handcode all your ZAML. Uh but they have started work on a ZAML designer in 1.7
3:19:16
started work on a ZAML designer in 1.7
3:19:16
started work on a ZAML designer in 1.7 and they'll continue that work in
3:19:19
and they'll continue that work in
3:19:19
and they'll continue that work in 1.8. And this QR code goes out to the
3:19:22
1.8. And this QR code goes out to the
3:19:22
1.8. And this QR code goes out to the road map for Windows app
3:19:26
road map for Windows app
3:19:26
road map for Windows app SDK. And let's see if we have a minute
3:19:30
SDK. And let's see if we have a minute
3:19:30
SDK. And let's see if we have a minute left. I have one other demo that's not
3:19:32
left. I have one other demo that's not
3:19:32
left. I have one other demo that's not part of the slides, but it's pretty
3:19:33
part of the slides, but it's pretty
3:19:33
part of the slides, but it's pretty cool. Um, in the current experimental
3:19:36
cool. Um, in the current experimental
3:19:36
cool. Um, in the current experimental releases of Windows App SDK, there's
3:19:38
releases of Windows App SDK, there's
3:19:38
releases of Windows App SDK, there's some AI stuff that you can
3:19:40
some AI stuff that you can
3:19:41
some AI stuff that you can do. So, this Windows Copilot
3:19:47
runtime, this uh project can only run if
3:19:50
runtime, this uh project can only run if
3:19:50
runtime, this uh project can only run if you have a Copilot Plus PC that's got
3:19:52
you have a Copilot Plus PC that's got
3:19:52
you have a Copilot Plus PC that's got the local uh Fi Silica AI model on
3:19:56
the local uh Fi Silica AI model on
3:19:56
the local uh Fi Silica AI model on it. So, what this
3:19:59
it. So, what this
3:19:59
it. So, what this has, let's just run it and you'll see
3:20:02
has, let's just run it and you'll see
3:20:02
has, let's just run it and you'll see what we've got.
3:20:04
what we've got.
3:20:04
what we've got. So, this is going to use the local model
3:20:05
So, this is going to use the local model
3:20:05
So, this is going to use the local model on my
3:20:06
on my
3:20:07
on my machine. And if I pop up task manager,
3:20:10
machine. And if I pop up task manager,
3:20:10
machine. And if I pop up task manager, we can
3:20:11
we can
3:20:11
we can watch the uh MPU do its work. So, here's
3:20:16
watch the uh MPU do its work. So, here's
3:20:16
watch the uh MPU do its work. So, here's my MPU, my neural processing unit on my
3:20:22
machine. And you'll be able to see the
3:20:24
machine. And you'll be able to see the
3:20:24
machine. And you'll be able to see the uh the GPU and CPU activity as well as
3:20:28
uh the GPU and CPU activity as well as
3:20:28
uh the GPU and CPU activity as well as we run this demo. Let's see if we can
3:20:30
we run this demo. Let's see if we can
3:20:30
we run this demo. Let's see if we can resize this a little bit to get
3:20:31
resize this a little bit to get
3:20:31
resize this a little bit to get everything to fit.
3:20:42
All
3:20:43
All
3:20:43
All right. So here I have a prompt provide
3:20:46
right. So here I have a prompt provide
3:20:46
right. So here I have a prompt provide the molecular formula for gl glucose and
3:20:48
the molecular formula for gl glucose and
3:20:48
the molecular formula for gl glucose and explain its properties. And we're asking
3:20:51
explain its properties. And we're asking
3:20:51
explain its properties. And we're asking it to please uh give us some markdown
3:20:53
it to please uh give us some markdown
3:20:53
it to please uh give us some markdown formatting to make it easy to
3:20:55
formatting to make it easy to
3:20:55
formatting to make it easy to read. So in these APIs there are
3:20:58
read. So in these APIs there are
3:20:58
read. So in these APIs there are different kinds of queries that you can
3:20:59
different kinds of queries that you can
3:20:59
different kinds of queries that you can run against the local model. You can do
3:21:01
run against the local model. You can do
3:21:01
run against the local model. You can do a general query which is just uh you
3:21:03
a general query which is just uh you
3:21:03
a general query which is just uh you know your usual questions that you'd ask
3:21:05
know your usual questions that you'd ask
3:21:05
know your usual questions that you'd ask the AI. Um you can ask it to rewrite
3:21:07
the AI. Um you can ask it to rewrite
3:21:07
the AI. Um you can ask it to rewrite your text. Summarize text. If you have a
3:21:10
your text. Summarize text. If you have a
3:21:10
your text. Summarize text. If you have a multi-page item that you'd um paste into
3:21:13
multi-page item that you'd um paste into
3:21:13
multi-page item that you'd um paste into here, you can ask it to summarize it.
3:21:15
here, you can ask it to summarize it.
3:21:15
here, you can ask it to summarize it. And you can also do text to table which
3:21:17
And you can also do text to table which
3:21:17
And you can also do text to table which will create a table of items from
3:21:19
will create a table of items from
3:21:19
will create a table of items from whatever you paste in there. But we just
3:21:22
whatever you paste in there. But we just
3:21:22
whatever you paste in there. But we just do a general query quickly here. And
3:21:24
do a general query quickly here. And
3:21:24
do a general query quickly here. And it's
3:21:26
it's
3:21:26
it's thinking. And we should see the MPU
3:21:29
thinking. And we should see the MPU
3:21:29
thinking. And we should see the MPU start to take off a little bit. Starting
3:21:31
start to take off a little bit. Starting
3:21:31
start to take off a little bit. Starting to get busy. There it
3:21:34
to get busy. There it
3:21:34
to get busy. There it goes. Meanwhile, my CPU is pretty flat.
3:21:37
goes. Meanwhile, my CPU is pretty flat.
3:21:37
goes. Meanwhile, my CPU is pretty flat. Not much going on there. GPU is also not
3:21:40
Not much going on there. GPU is also not
3:21:40
Not much going on there. GPU is also not working. Everything's happening on the
3:21:43
working. Everything's happening on the
3:21:43
working. Everything's happening on the MPU. And in the code
3:21:45
MPU. And in the code
3:21:45
MPU. And in the code here, I'm telling it to read the data
3:21:49
here, I'm telling it to read the data
3:21:49
here, I'm telling it to read the data back to me as it's being generated. So
3:21:51
back to me as it's being generated. So
3:21:51
back to me as it's being generated. So we don't have to wait a long time for
3:21:52
we don't have to wait a long time for
3:21:52
we don't have to wait a long time for the whole whole thing to be created
3:21:54
the whole whole thing to be created
3:21:54
the whole whole thing to be created before I show you the output. We're
3:21:57
before I show you the output. We're
3:21:57
before I show you the output. We're getting this streamed back to the app
3:22:02
asynchronously. So we'll wait for this
3:22:04
asynchronously. So we'll wait for this
3:22:04
asynchronously. So we'll wait for this to finish up. There should just be a
3:22:05
to finish up. There should just be a
3:22:05
to finish up. There should just be a couple more lines and then I'll show you
3:22:08
couple more lines and then I'll show you
3:22:08
couple more lines and then I'll show you the code and we'll wrap
3:22:15
up. This checkbox show progress. This is
3:22:18
up. This checkbox show progress. This is
3:22:18
up. This checkbox show progress. This is what controls whether it feeds it back
3:22:20
what controls whether it feeds it back
3:22:20
what controls whether it feeds it back as it's going or if it just does one
3:22:24
as it's going or if it just does one
3:22:24
as it's going or if it just does one call and wait for everything to come
3:22:28
back. And while we wait Oh, there we go.
3:22:31
back. And while we wait Oh, there we go.
3:22:31
back. And while we wait Oh, there we go. It's finished. The other thing I have
3:22:33
It's finished. The other thing I have
3:22:33
It's finished. The other thing I have here is a checkbox to say use a strict
3:22:34
here is a checkbox to say use a strict
3:22:34
here is a checkbox to say use a strict content filter. So that will filter
3:22:37
content filter. So that will filter
3:22:37
content filter. So that will filter content
3:22:38
content
3:22:38
content um has violence filters, has different
3:22:41
um has violence filters, has different
3:22:41
um has violence filters, has different filters that I'll show you in the code
3:22:43
filters that I'll show you in the code
3:22:43
filters that I'll show you in the code here super quick.
3:22:45
here super quick.
3:22:45
here super quick. Let's close that.
3:22:50
So, here's where I'm checking if we want
3:22:53
So, here's where I'm checking if we want
3:22:53
So, here's where I'm checking if we want to
3:22:54
to
3:22:54
to um show progress. So, if we want to show
3:22:57
um show progress. So, if we want to show
3:22:57
um show progress. So, if we want to show progress, it uses this generate response
3:23:00
progress, it uses this generate response
3:23:00
progress, it uses this generate response with progress. And then we've got a call
3:23:03
with progress. And then we've got a call
3:23:03
with progress. And then we've got a call back to show the results as they're
3:23:07
back to show the results as they're
3:23:07
back to show the results as they're coming in. If I want to see everything
3:23:09
coming in. If I want to see everything
3:23:09
coming in. If I want to see everything at once, I just make a single call to
3:23:11
at once, I just make a single call to
3:23:11
at once, I just make a single call to generate response async and I get
3:23:14
generate response async and I get
3:23:14
generate response async and I get everything in the result and populate
3:23:16
everything in the result and populate
3:23:16
everything in the result and populate that at the end.
3:23:18
that at the end.
3:23:18
that at the end. Uh the other thing I've got is the like
3:23:21
Uh the other thing I've got is the like
3:23:21
Uh the other thing I've got is the like I mentioned content
3:23:23
I mentioned content
3:23:23
I mentioned content filters and I've got
3:23:25
filters and I've got
3:23:25
filters and I've got a thing down here apply content filters.
3:23:28
a thing down here apply content filters.
3:23:28
a thing down here apply content filters. So if the check box is checked it's
3:23:31
So if the check box is checked it's
3:23:31
So if the check box is checked it's setting all these filter options for
3:23:32
setting all these filter options for
3:23:32
setting all these filter options for violence uh hate content sexual content
3:23:36
violence uh hate content sexual content
3:23:36
violence uh hate content sexual content self harm content. So all of that can be
3:23:37
self harm content. So all of that can be
3:23:38
self harm content. So all of that can be filtered out with these
3:23:42
filters and this is all running locally.
3:23:45
filters and this is all running locally.
3:23:45
filters and this is all running locally. nothing pinging the web for this AI
3:23:50
call. So, like I said, that's in the
3:23:52
call. So, like I said, that's in the
3:23:52
call. So, like I said, that's in the experimental release. Um, hopefully
3:23:54
experimental release. Um, hopefully
3:23:54
experimental release. Um, hopefully it'll make it out to a stable release
3:23:56
it'll make it out to a stable release
3:23:56
it'll make it out to a stable release very
3:24:00
soon. And that's all I've got. Do we
3:24:04
soon. And that's all I've got. Do we
3:24:04
soon. And that's all I've got. Do we have any questions in the chat?
3:24:09
Uh, hi Alvin. Yeah, we have we have a
3:24:11
Uh, hi Alvin. Yeah, we have we have a
3:24:11
Uh, hi Alvin. Yeah, we have we have a few questions. Uh, first is is a
3:24:13
few questions. Uh, first is is a
3:24:13
few questions. Uh, first is is a compliment come from Deepak. He says
3:24:15
compliment come from Deepak. He says
3:24:15
compliment come from Deepak. He says it's really amazing and I yeah I I I I
3:24:18
it's really amazing and I yeah I I I I
3:24:18
it's really amazing and I yeah I I I I agree with him. Uh it was really nice to
3:24:20
agree with him. Uh it was really nice to
3:24:20
agree with him. Uh it was really nice to have those those demos there. We have a
3:24:22
have those those demos there. We have a
3:24:22
have those those demos there. We have a few one. Let's start with Tomar is
3:24:24
few one. Let's start with Tomar is
3:24:24
few one. Let's start with Tomar is asking what best practices do you
3:24:26
asking what best practices do you
3:24:26
asking what best practices do you recommend for structuring a win UI app
3:24:29
recommend for structuring a win UI app
3:24:29
recommend for structuring a win UI app to keep it maintainable and scalable.
3:24:32
to keep it maintainable and scalable.
3:24:32
to keep it maintainable and scalable. So I would definitely recommend uh using
3:24:35
So I would definitely recommend uh using
3:24:35
So I would definitely recommend uh using some type of MVVM whether you roll your
3:24:37
some type of MVVM whether you roll your
3:24:37
some type of MVVM whether you roll your own or you use the toolkit. I prefer the
3:24:39
own or you use the toolkit. I prefer the
3:24:40
own or you use the toolkit. I prefer the toolkit to reduce the amount of code. Um
3:24:42
toolkit to reduce the amount of code. Um
3:24:42
toolkit to reduce the amount of code. Um but I would do that. Um also uh using
3:24:46
but I would do that. Um also uh using
3:24:46
but I would do that. Um also uh using dependency injection. Um in my projects
3:24:49
dependency injection. Um in my projects
3:24:49
dependency injection. Um in my projects I just use the built-in uhnet host for
3:24:52
I just use the built-in uhnet host for
3:24:52
I just use the built-in uhnet host for the the DI container. Um and in some of
3:24:56
the the DI container. Um and in some of
3:24:56
the the DI container. Um and in some of the projects I've got some services like
3:24:59
the projects I've got some services like
3:24:59
the projects I've got some services like I've got a navigation service for doing
3:25:01
I've got a navigation service for doing
3:25:01
I've got a navigation service for doing that page navigation. Um that's in the
3:25:04
that page navigation. Um that's in the
3:25:04
that page navigation. Um that's in the DI container. Um I've got some other
3:25:07
DI container. Um I've got some other
3:25:07
DI container. Um I've got some other services for calling different um online
3:25:10
services for calling different um online
3:25:10
services for calling different um online APIs. So, by using DI and MVVM, um those
3:25:14
APIs. So, by using DI and MVVM, um those
3:25:14
APIs. So, by using DI and MVVM, um those are the best ways to uh keep your app
3:25:17
are the best ways to uh keep your app
3:25:17
are the best ways to uh keep your app scalable. Um I also recommend using the
3:25:20
scalable. Um I also recommend using the
3:25:20
scalable. Um I also recommend using the theme resources unless you're branding
3:25:22
theme resources unless you're branding
3:25:22
theme resources unless you're branding your app. Um people like to see the
3:25:25
your app. Um people like to see the
3:25:25
your app. Um people like to see the their Windows colors and dark mode,
3:25:27
their Windows colors and dark mode,
3:25:27
their Windows colors and dark mode, light mode picked up automatically.
3:25:31
light mode picked up automatically.
3:25:31
light mode picked up automatically. Perfect. Thanks for asking that and
3:25:33
Perfect. Thanks for asking that and
3:25:33
Perfect. Thanks for asking that and thanks Roy for your question. Let's take
3:25:35
thanks Roy for your question. Let's take
3:25:35
thanks Roy for your question. Let's take another one from Scott. He's asking can
3:25:37
another one from Scott. He's asking can
3:25:37
another one from Scott. He's asking can you explain the differences between
3:25:38
you explain the differences between
3:25:38
you explain the differences between various deployment options like
3:25:41
various deployment options like
3:25:41
various deployment options like Microsoft Store and Windgate and when to
3:25:43
Microsoft Store and Windgate and when to
3:25:43
Microsoft Store and Windgate and when to use which?
3:25:45
use which?
3:25:45
use which? Um so Microsoft Store your app will only
3:25:48
Um so Microsoft Store your app will only
3:25:48
Um so Microsoft Store your app will only be available through the store. Um with
3:25:51
be available through the store. Um with
3:25:51
be available through the store. Um with Windet you can make it um available at
3:25:53
Windet you can make it um available at
3:25:53
Windet you can make it um available at the command line. So people can just uh
3:25:56
the command line. So people can just uh
3:25:56
the command line. So people can just uh install at the command line just say
3:25:58
install at the command line just say
3:25:58
install at the command line just say winget and the name of your package. Um
3:26:01
winget and the name of your package. Um
3:26:01
winget and the name of your package. Um for enterprises there are also some
3:26:03
for enterprises there are also some
3:26:03
for enterprises there are also some enterprise deployment that's where you
3:26:05
enterprise deployment that's where you
3:26:05
enterprise deployment that's where you can deploy your workstations through
3:26:07
can deploy your workstations through
3:26:07
can deploy your workstations through intoune and other uh enterprise
3:26:09
intoune and other uh enterprise
3:26:09
intoune and other uh enterprise deployment solutions. Um so it depends
3:26:12
deployment solutions. Um so it depends
3:26:12
deployment solutions. Um so it depends if you are targeting um say if you have
3:26:16
if you are targeting um say if you have
3:26:16
if you are targeting um say if you have a consumer app you definitely want to go
3:26:17
a consumer app you definitely want to go
3:26:17
a consumer app you definitely want to go to the store. You have something more
3:26:19
to the store. You have something more
3:26:19
to the store. You have something more for focused toward developers maybe go
3:26:21
for focused toward developers maybe go
3:26:21
for focused toward developers maybe go up through winget and then through one
3:26:23
up through winget and then through one
3:26:23
up through winget and then through one of the other uh installers or the uh in
3:26:26
of the other uh installers or the uh in
3:26:26

3:26:32
Perfect. Let's take final one that's
3:26:32
Perfect. Let's take final one that's coming from Khan Singh. He's asking how
3:26:35
coming from Khan Singh. He's asking how
3:26:35
coming from Khan Singh. He's asking how seamless is it to use both net and
3:26:37
seamless is it to use both net and
3:26:37
seamless is it to use both net and vinati APIs together in a modern VUI
3:26:40
vinati APIs together in a modern VUI
3:26:40
vinati APIs together in a modern VUI application. Are there any caveats?
3:26:43
application. Are there any caveats?
3:26:43
application. Are there any caveats? Um yeah, it can be tricky knowing when
3:26:46
Um yeah, it can be tricky knowing when
3:26:46
Um yeah, it can be tricky knowing when to use what. You can use all of these
3:26:48
to use what. You can use all of these
3:26:48
to use what. You can use all of these together.
3:26:50
together.
3:26:50
together. Um, some of the there's some things in
3:26:54
Um, some of the there's some things in
3:26:54
Um, some of the there's some things in the WinRT stuff that you can't use
3:26:56
the WinRT stuff that you can't use
3:26:56
the WinRT stuff that you can't use anything that's like u tied to the UI
3:26:59
anything that's like u tied to the UI
3:26:59
anything that's like u tied to the UI like WinRT has a lot of uh UI specific
3:27:02
like WinRT has a lot of uh UI specific
3:27:02
like WinRT has a lot of uh UI specific stuff in it that was tied to UWP. You
3:27:05
stuff in it that was tied to UWP. You
3:27:05
stuff in it that was tied to UWP. You obviously can't use any of those, but uh
3:27:07
obviously can't use any of those, but uh
3:27:07
obviously can't use any of those, but uh anything else like for um file access.
3:27:10
anything else like for um file access.
3:27:10
anything else like for um file access. So you've got access to the uh the file
3:27:13
So you've got access to the uh the file
3:27:13
So you've got access to the uh the file APIs both in WinRT and.net. Um, if you
3:27:17
APIs both in WinRT and.net. Um, if you
3:27:17
APIs both in WinRT and.net. Um, if you wanted your app to be more uh like a
3:27:19
wanted your app to be more uh like a
3:27:19
wanted your app to be more uh like a sandbox app like UWP, um, and you just
3:27:23
sandbox app like UWP, um, and you just
3:27:23
sandbox app like UWP, um, and you just want to have it have access to local uh,
3:27:26
want to have it have access to local uh,
3:27:26
want to have it have access to local uh, storage, you would use those WinRT APIs.
3:27:29
storage, you would use those WinRT APIs.
3:27:29
storage, you would use those WinRT APIs. If you want to have full access to
3:27:30
If you want to have full access to
3:27:30
If you want to have full access to everything, you you know, it's an
3:27:32
everything, you you know, it's an
3:27:32
everything, you you know, it's an unrestricted app. Uh, you can use the
3:27:34
unrestricted app. Uh, you can use the
3:27:34
unrestricted app. Uh, you can use the net file API. So, it really depends how
3:27:38
net file API. So, it really depends how
3:27:38
net file API. So, it really depends how restrictive you want to be.
3:27:41
restrictive you want to be.
3:27:41
restrictive you want to be. Perfect. So, maybe maybe uh, uh, okay.
3:27:45
Perfect. So, maybe maybe uh, uh, okay.
3:27:45
Perfect. So, maybe maybe uh, uh, okay. Do we have let's Okay, Kam Singh says
3:27:47
Do we have let's Okay, Kam Singh says
3:27:47
Do we have let's Okay, Kam Singh says thank you. Let's take one more question
3:27:49
thank you. Let's take one more question
3:27:49
thank you. Let's take one more question then we'll just wrap it up, right? I
3:27:50
then we'll just wrap it up, right? I
3:27:50
then we'll just wrap it up, right? I think the question will keep on flowing
3:27:52
think the question will keep on flowing
3:27:52
think the question will keep on flowing as long as you are on the screen. Um um
3:27:55
as long as you are on the screen. Um um
3:27:55
as long as you are on the screen. Um um for developers completely new to bin UI
3:27:58
for developers completely new to bin UI
3:27:58
for developers completely new to bin UI and Windows app SDK. What are the first
3:28:00
and Windows app SDK. What are the first
3:28:00
and Windows app SDK. What are the first key steps to get project off the ground?
3:28:04
key steps to get project off the ground?
3:28:04
key steps to get project off the ground? Um so it's important I would say to
3:28:06
Um so it's important I would say to
3:28:06
Um so it's important I would say to learn uh the ZAML if you've never used
3:28:09
learn uh the ZAML if you've never used
3:28:09
learn uh the ZAML if you've never used um ZAML with WPF or one of the other
3:28:12
um ZAML with WPF or one of the other
3:28:12
um ZAML with WPF or one of the other frameworks Maui. They're all pretty
3:28:14
frameworks Maui. They're all pretty
3:28:14
frameworks Maui. They're all pretty similar. They are slightly different
3:28:15
similar. They are slightly different
3:28:15
similar. They are slightly different schemas when you go between WPF, WinUI,
3:28:18
schemas when you go between WPF, WinUI,
3:28:18
schemas when you go between WPF, WinUI, Maui. Um like I mentioned earlier, UWP
3:28:21
Maui. Um like I mentioned earlier, UWP
3:28:21
Maui. Um like I mentioned earlier, UWP is almost exactly the same as WinUI. So
3:28:23
is almost exactly the same as WinUI. So
3:28:23
is almost exactly the same as WinUI. So if you're coming from there, there
3:28:25
if you're coming from there, there
3:28:25
if you're coming from there, there shouldn't be much of a learning curve.
3:28:26
shouldn't be much of a learning curve.
3:28:26
shouldn't be much of a learning curve. Um but without the visual designer, it's
3:28:29
Um but without the visual designer, it's
3:28:29
Um but without the visual designer, it's important to understand how ZAML works.
3:28:31
important to understand how ZAML works.
3:28:31
important to understand how ZAML works. And um there are a lot of good resources
3:28:33
And um there are a lot of good resources
3:28:33
And um there are a lot of good resources up on Microsoft Learn um some different
3:28:36
up on Microsoft Learn um some different
3:28:36
up on Microsoft Learn um some different books out there, including mine that get

3:28:43
Um yeah, that's the biggest part. And if
3:28:43
Um yeah, that's the biggest part. And if you're familiar with net, the rest of it
3:28:44
you're familiar with net, the rest of it
3:28:44
you're familiar with net, the rest of it should be pretty simple.
3:28:47
should be pretty simple.
3:28:47
should be pretty simple. Perfect, Elvin. So that is it. So thank
