Creating a resolver

We need to create a helper class that will ease the process of resolving object graphs through Autofac. This will help us create types based on a configured IoC container.

In this project, we will use Autofac as the IoC library:

1. Install the Autofac NuGet package in the Chat project.
2. Create a new class called Resolver in the Chat project.
3. Add a private static field called container of the IContainer type (from Autofac).
4. Add a public static method called Initialize with IContainer as a parameter. Set the value of the parameter to the container field.
5. Add a generic static public method called Resolve, which will return an instance that is based on the argument type, with the Resolve method of IContainer:

using Autofac;

public class Resolver
{
     private static IContainer container;
 
     public static void Initialize(IContainer container)
{
          Resolver...
