Return same instance for multiple interfaces

builder.RegisterType<StandardConsole>()
   .As<IStartable>()
   .As<IConsumer<ConsoleCommand>>()
   .SingleInstance();

Very widely used feature of Autofac- any problems then there is a bug somewhere 🙂

Edit By the looks of it, you’re after the overload of As() that takes an IEnumerable<Type>() – check out all of the As() overloads using IntelliSense, something there should fit your scenario. As another commenter noted, you need to update the question with all of the info.
