Sir, you are correct, nice catch! I fixed it in the **Expected Behavior** section. Here's the corresponding _passing_ test from my [repo](https://github.com/ViktorDolezel/AutofacDecorators/blob/master/Program.cs) (without the decorator). ```csharp [Test] public void ResolveAllCommandHandlers_IsSuccessful()...

Hi, thanks for looking into it. Here's a failing test that can be added to the [OpenGenericDecoratorTests](https://github.com/autofac/Autofac/blob/develop/test/Autofac.Test/Features/Decorators/OpenGenericDecoratorTests.cs). ``` [Fact] public void ResolvesMultipleDecoratedServicesWhenResolvedByOtherServices() { var builder = new ContainerBuilder(); builder.RegisterGeneric(typeof(ImplementorA)).As(typeof(IDecoratedService)).As(typeof(IService)); builder.RegisterGeneric(typeof(ImplementorB)).As(typeof(IDecoratedService)).As(typeof(IService));...

I'll give it a try but it could be out of my league.
