Hello friends, welcome to the next lab. In this lab, we will learn what things we are using our what things were required to configure our APA as we're sitting default template. So the services dot add MVC method already added. And the compatibility version is whatever the version we use. If you take the previous version is 2.0 2.1 and 2.2, we're using the 2.21. This metric required for living with this team, and you need to add if you select a blank template, then you need to add this method After that, one more thing, we need to add one more middleware in our requesting pipeline, you know, configure method.
So, here use MVC, using MVC is a middleware. And we already added this. Now I'm moving this middleware to above. Okay? And now I'm commenting out this code, okay. So, let's talk about MVC.
What is MVC? MVC is an architectural pattern, model, view and controller. Okay. Now when you can see the image here, model view and controller no keep use Finn one request. Then this request goes to first controller, then controller process that request and by choosing appropriate model which is required or not, it depends on the request it sent result back to the rest of you. Then from this view, you can choose multiple views, but only one view at a single time means, what is the view be the view see the view on basis of request, whatever you want the output in which format you can say that appropriately This is a MVC pattern, but in APA there is no view no HTML page.
So, what is a view in Everything is good Let me see if there is a data representation and insurance when the data always in a JSON format. So, it is a few what we will see So, the terminology is used for Model Model is for passing the data or getting the data in order to form it is a model view for display purpose and controller for handle the request Okay. Now, we see use MVC method we add the middleware in a request pipeline add MVC method in service. Now, one more thing is previous version dotnet core 2.1 2.0 When you publish your application the all dependencies will be included in that folder okay. But this tuple to current version there is one concept runtime. So, anytime store you can relate as in a previous was an updated get me global assembly cache means whatever things it required for application, it is a reference from that folder.
Now, if if we weren't sick, there is a gap present. You can see here okay, you can see this is back and then install the packages With required it is directly reference from here. And if we use which there is only these files, and if we publish this app, there's little bit, add one or more dependencies. So, meta package I already explained in a previous or starting lab. What is a meta package? It is a list of dependencies.
Okay. So that's all about these things required for building an API, if we select a blank template, but as we are using the pay template, so these are MVC use MVC method already added here. So now we need to add this. So thank you for watching. We will meet in the next lecture.
