Using IronPython 0.9.2. on .NET 2.0.50.215.44 w/ SharpDevelop 2.0.0 build 408
I've been trying to use a modified version of the supplied Embed4.cs example to run from within AutoCAD (just to see if I can get it to work). It compiles fine but when I load and run it I get the exception listed below. I tried "caspol -m -af c:\path\to\IronPython.dll" but it errors out saying IronPython.dll is not strong named. Do I need to recompile IronPython.dll or am I heading in the wrong direction all together? Any help/tips would be greatly appreciated.
Regards,
Tim Riley
