How Do I get the Current UserId in an ASP.NET Core Identity View or Controller

Accessing the current UserId (ASPNetUsers Id) of an ASP.NET Core Identity application is essential to creating user-specific applications and filtering data based on a specific user.

When users create (register) an account in an ASP.NET Core Identity application, a distinct user ID is generated and added to the SQL Server database ASPNetUsers' table. This table was created when migrations were applied to initialize the database. This database table also stores profile data, passwords, e-mail addresses, and other personal data. Generally speaking, ASP.NET Core Identity adds user interface login and role functionality to ASP.NET Core web apps.
