Identity customizations
In the previous unit, you added default ASP.NET Core Identity functionality to an ASP.NET Core web app. In this unit, you learn about customizing and extending ASP.NET Core Identity.
Extending the Identity data model
By default, Identity represents a user with an IdentityUser class. In the previous unit, when you ran the scaffolding tool, you created a class named RazorPagesPizzaUser that inherits from IdentityUser. In the next unit, you'll modify the derived class to include properties to store the user's first and last name.
Extending the data model requires changes to the underlying database. Luckily, Entity Framework Core makes this task simple with migrations.
Customizing the Identity user interface
The default Identity UI components are packaged in a .NET Standard Razor Class Library (RCL). Because an RCL is used, few files are added to the project when using the default UI. There is no need for physical .cshtml files in the project because the RCL provides the UI components.
When customizing the UI, you must first use the aspnet-codegenerator tool again to create .cshtml files to be used in lieu of the RCL. The tool allows you to explicitly select which files are created. UI components from the RCL are used if the corresponding files aren't present.
Summary
In this unit, you learned about extending and customizing ASP.NET Core Identity. In the next unit, you can customize the Identity UI.
