Remarks

You only need to use this functionality when you want Entity Framework to resolve the services it uses from an external System.IServiceProvider. If you are not using an external System.IServiceProvider Entity Framework will take care of creating the services it requires.

The database you are using will also define extension methods that can be called on the returned to register the services required by the database. For example, when using Microsoft.EntityFrameworkCore.SqlServer you would call collection.AddEntityFrameworkSqlServer().

For derived contexts to be registered in the System.IServiceProvider and resolve their services from the System.IServiceProvider you must chain a call to the AddDbContext<TContext>(IServiceCollection, Action<DbContextOptionsBuilder>, ServiceLifetime) method on the returned .
