MVC in ASP.NET Core - Models in ASP.NET

MVC in ASP.NET Core - Models in ASP.NET-copy

This course is for you if you’re looking to start your journey in either full-stack MVC or backend development with ASP.NET Core.

In the first half of the course, you’ll learn about the Model-View-Controller design pattern and how you can use it to organize and develop your web application. You’ll then dive into JSON web APIs which allow communication between your back-end ASP.NET application and front-end web/mobile application.

In the latter half, you’ll learn about the repository pattern, how relationships work, and how to add authentication and authorization to your application.

By the end of this course, you will have the confidence to develop your own applications in ASP.NET Core.

Developing Applications with ASP.NET Core

# Updating Startup.cs

To allow repository injection into your controllers, the `ConfigureServices()` method inside `Startup.cs` needs to be updated by adding the following two lines of code.

// services.AddScoped<IUserRepo, MockUserRepo>();
services.AddScoped<IUserRepo, SqlUserRepo>();

One of them is commented out so you can select and choose which repository you want to inject at a given time. If you want to inject the mock repository, you will remove the comment tag (`//`) from the first line and place it at the start of the second line.

Now you can inject your repository into your controllers.

# Updating the controller

For demonstration purposes, you are injecting your repository into `UserController` that was previously used to generate APIs. Previously, database context was injected, and now it has been replaced with `IUserRepo`. Hence the repository is being injected into your controller via the constructor.

Learn how you can inject your repositories into your controller.
