Mocking .Net2.0 static methods

Hi everyone

I have the following code that throws a TypeMockException: Cannot use Return in this sequence, there must be a mocked statement first.

using (RecordExpectations recorder = RecorderManager.StartRecording())
{
File.Exists(null);
recorder.Return(false);
}

The exception occurs on the recorder.Return(false); line. I have tried this with string.IsNullOrEmpty(null); and Directory.Exists(null); and the same result occurs. Am I doing something wrong?

Ide: VS2005
TypeMock version: 3.6.1.0 with fix for FailWhenCalled (See this thread: https://www.typemock.com/community/viewtopic.php?t=402)
NUnit version: .Net 2 2.2.8
