Until VB catches up with C# in the lambda support realm, here is how you can accomplish those Moq or Rhino.Mocks style verifications in VB:
dim someSub as Action(Of double) = AddressOf mockObject.SomeSubRhino.Mocks.Expect.Call( someSub)
It’s very frustrating going from the full support in C# to VB, but I’m finding sufficient workaround for most items. I shouldn’t be so hard on VB. C# doesn’t support inline of Xml which is pretty friggin’ sweet.

After seeing that title again, it should say “kinda”. These are obviously not lambda expressions, but simply a way to take advantage of some of the nice support for delegate invokation in some Mocking Frameworks.
