Well, currently you can't moq much with
VB.NET. It just doesn't
support multi statement or void returning
lambdas (although you can use the AddressOf with a normal delegate).
I tried to set up
VB.NET samples in mocking-frameworks-compare project
(
http://code.google.com/p/mocking-frameworks-compare/ ) but didn't
get anywhere so I gave up until VB10 is out.
In VB10 all that lambda things should be available.
