C# Mocking Framework that supports optional parameters and .Net 4.0

Question

Is there a mocking framework that exists for C# that supports .Net 4.0 and C# completely. Specifically, I'm looking for it to support optional parameters.

Answer 1

I was able to get Moq to handle this by writing an extension method that accepted a method name and a dictionary of the parameter names and values that you did want to specify and the extension method creates calls to It.IsAny() for all the parameters that you didn't specify:

Answer 2

I'm pretty sure MOQ does - http://code.google.com/p/moq/
