Hi all,
I've found what appears to be a bug, exposed by the following code:
using Rhino.Mocks;
namespace TestMocks
{
public class Foo
{
public virtual void Bar<T>(out T obj)
{
obj = default(T);
}
}
class Program
{
static void Main(string[] args)
{
Foo foo = MockRepository.GeneratePartialMock<Foo>();
object baz;
foo.Bar(out baz); // throws BadImageFormatException
}
}
}
Causes exception:
Message: An attempt was made to load a program with an incorrect
format. (Exception from HRESULT: 0x8007000B)
Source: DynamicProxyGenAssembly2

I have tried the current release of Rhino Mocks and the nightly. My
environment is .NET 3.5 SP1 and it also happens in the .NET 4 RC.
It only happens when Foo.Bar is virtual, has a generic out parameter
and is being partially mocked. In any other circumstances I've tried,
the problem doesn't occur.
Thanks,
Cameron
