How to get all registered service types in Autofac

Question

I have an Autofac container and I would like to be able to retrieve all the registered service types (not the implementation types, but the types they are registered as).

How can I get this information from an IComponentContext?

You can use this:

var services =
    context.ComponentRegistry.Registrations.SelectMany(x => x.Services)
           .OfType<IServiceWithType>()
           .Select(x => x.ServiceType);
