Hi Doug,

Thanks for trying to help but please see the archives for the background on this issue as I've already done what you suggest and it doesn't work for my mixed-mode, .NET 2.0 generated DLL.

I have had no problems by putting the dll path on sys.path. Perhaps
Python is giving you a bad pathDir (maybe leaving out the drive?):

 pathDir = os.path.dirname(FULLPATH)

Here is an example where Graphics.dll is in /home/dblank/Calico/modules:

linux$ mono bin/ipy.exe
IronPython 3.0 ( on .NET 2.0.50727.1433
Type "help", "copyright", "credits" or "license" for more information.
>>> import clr
>>> import sys
>>> sys.path.append("/home/dblank/Calico/modules")
>>> clr.AddReference("Graphics.dll")
>>> import Graphics

Hope that helps,
