Remarks

You only need to use this functionality when you want Entity Framework to resolve the services it uses from an external IServiceProvider. If you are not using an external 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 IServiceCollection 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 IServiceProvider and resolve their services from the IServiceProvider you must chain a call to the AddDbContext<TContext>(IServiceCollection, Action<DbContextOptionsBuilder>, ServiceLifetime) method on the returned IServiceCollection.
