Very specific issue of converting C # to VB.NET

Question

I am currently working on a project that uses the AutoFac Inversion of Control container.

I am trying to convert example code from C # to the code base of my existing project, which is written in VB.NET, and I ran into a problem.

Source line of code:

EventHub.Subscribe<HandshakingEvent>(container.Resolve<HandshakeAuthenticator>().CheckHandshake);

Which I converted to:

EventHub.Subscribe(Of HandshakingEvent)(Container.Resolve(Of HandshakeAuthenticator)().CheckHandshake)

But - this causes an error: "The argument is not specified for the parameter" ev "CheckHandshake".

The parameter type for the EventHub.Subscribe (Of HandshakingEvent) procedure is System.Action (of HandshakingEvent)

I see what the problem is, I'm just not sure what to do with it! I tried using "AddressOf", but that does not work either.

Thanks in advance ... - Chris
