When I follow your instructions, and register DialogFactory and IDialogFactory, I still get an exception on start-up, that ILifeTimeScope is not marked [Serializable]
Exception: Type ‘Autofac.Core.Lifetime.LifetimeScope’ in Assembly ‘Autofac, Version=4.0.1.0, Culture=neutral, PublicKeyToken=17863af14b0044da’ is not marked as serializable.

.Keyed(FiberModule.Key_DoNotSerialize)
.AsImplementedInterfaces()
.InstancePerLifetimeScope();
