ref keyword in interface method declaration causes exception

[Pjanssen]

I'm writing unittests for an application which makes use of a third party API, with some generated interfaces. I was getting some strange exceptions trying to create a mock object for a complex interface. After much digging, I found that one of these interfaces it extends has a declaration with a ref keyword in it:

public interface IReferenceMaker
{
   RefResult NotifyRefChanged(ref UIntPtr partID, RefMessage message);
}

When trying to create a mock object for this interface, an exception is thrown when accessing the Object property: ArgumentException: Type System.UIntPtr could not be converted to a OpCode.

Mock<IReferenceMaker> mockRefMaker = new Mock<IReferenceMaker>();
IReferenceMaker refMaker = mockRefMaker.Object;

Unfortunately I can't change the interface in any way, so I'm looking for a way to work around the issue on the Moq side.
Any ideas?

edit: I noticed in the stacktrace that the exception is thrown in Castle, so I submitted an issue report there too.

yuck, could you also post that question to the Castle DynamicProxy guys?

It appears this was fix when upgrading to Castle 3.3.3 #204.

@dtuchlinsky: Thanks for the hint. This was fixed back in version 4.2.1510.2205 (which was the first version based on Castle 3.3.3).
