Using a different ServiceProvider

Changing to a different or custom DI container is relatively easy if the other container already supports ASP.NET Core. Usually, the other container will use IServiceCollection to feed its own container. The third-party DI containers move the already-registered services to the other container by looping over the collection:

1. Let's start by using Autofac as a third-party container. Type the following command into your command line to load the NuGet package:

   dotnet add package Autofac.Extensions.DependencyInjection

Autofac is good for this because you are easily able to see what is happening here.

IServiceProviderFactory will create a ServiceProvider instance. The third-party container should provide one, if it supports ASP.NET Core.
