I recently upgraded from 4.5.2 to 6.0 and now have a several tests failing with a typemock exception.

The application I am developing tests for is based on the CSLA framework by Rockford Lotkha.

I am including the exception info, my unit test code, the class being tested, and the base class from CSLA where I can trace the issue to, prior to typemock throwing a fit:

This is the last method I can trace to:
protected P GetProperty<P>(PropertyInfo<P> propertyInfo)
      return GetProperty<P>(propertyInfo, Security.NoAccessBehavior.SuppressException);

////////// ERROR ////////////
A first chance exception of type 'System.ArgumentOutOfRangeException' occurred in TypeMock.dll

Additional information: Index was out of range. Must be non-negative and less than the size of the collection.
