Darryl, Does the issue only occur when you load the assembly from the CAG? I've typically used Assembly.LoadWithPartialName( 'NameOfMyAssembleyWithoutDotDLL' ) from CLR import MyClass with the DLL located in the PYTHONPATH.

I get this output on the console: CLR.System.BadImageFormatException: Exception from HRESULT: 0x8013141D. at System.Reflection.Assembly.nLoadImage(Byte[] rawAssembly, Byte[] rawSymbolStore, Evidence evidence, StackCrawlMark& stackMark) at System.Reflection.Assembly.Load(Byte[] rawAssembly) ------------------------- I have tried using import CLR.Huru.Plasma but it tells me that there is no module named Huru. The dll is in the GAC. I am able to access all System dlls and DirectX dlls, but not my own C# dll. http://www.urulive.com/blog/
