In this recipe, we will use Autofac as a DI container to compose our application's object graph. It is famous, performant, and has a lot of features.
ASP.NET Core has an out-of-the-box DI container. In this chapter, we'll use another DI container-Autofac. Autofac is very well-received by the community.

Autofac is also very light, but it has almost every feature that you would expect from a complete DI container library.
