Adding a reference to Autofac

Autofac lives in a NuGet package that we need to install, and we need to reference it in our project files. Proceed as follows:

1. Open up the NuGet package manager by right-clicking on the Solution node and clicking on Manage NuGet Packages for Solution... .
2. Click on Browse, and type Autofac in the search box.
3. Tick all the checkboxes under Project, scroll down, and click Install.

This will download and install Autofac into all your projects. The next step is to add some code that will allow us to use Autofac.
