By these above codes we take host object and use CreateScope and GetServices methods in order to use our database related classes.

Confirm that the libraries files are loaded in the environment you are testing. In validation, we will look at the client-side validation of the razor pages.

Razor Pages Architecture

He also has many years of experience with .NET C# and .NET MVC. This is basically the same that you wrote in the Index.cshtml razor page but uses Employee model class rather than a PageModel class.

Select the target Framework .NET 6 at the top of the Application based on your required target that you want and then click the Create button to create a new Razor Class Library application. The Razor markup file also contains a @model directive that binds the Razor Page to a specific page model. If we expand the Razor Page in Visual Studio, we find a page model class with the same name as the Razor Page with a .cs suffix. By default, this is the page model referenced by the Razor markup.

  • Using shared API Controllers in ASP.NET Core is fairly simple.
  • Flow of control in the program is governed by the methods of the CreateModel class and the repositories, rather than by the relationship between higher-level abstractions.
  • Better throughput on Azure and less resource consumption .
  • To store these entities, we should create a DataContext class.

Lets implement this interface with using Data layer objects. In our case Data layer represents from Entity Framework Core so we should use DataContext object. In order to use AspnetRunContext object which represent us DB Layer, the constructor should use dependency injection to inject the database context into the ProductRepository class. If you look at the Initial class you can see Up() and Down() methods which provide to prepare ASP.NET Core 3.1 Razor Lessons database scripts when database updated. So when you changed anything under the Entities folder, in order to reflect to database, first you should run add-migration command and see the changes on these migration classes. Most of the web applications following common steps when you start a new web application.

Again in this file, we can configure the environment. After definition of context class, we should recognize this class into asp.net core. ASP.NET Core has built-in Dependency Injection services (such as EF.Core DB context) are registered in DI when starting the application. Components that require these services are provided through constructor parameters with these parameters. For this action we should add DbContext object into ConfigureServices method.

But what if we can improve things and make it better. Well, in this post, let’s take a look at a clean way to add Startup class in ASP.NET Core 6 projects.
