[Ironpython-users] Windows C-DLL and find_module issues

[Slide]

IronPython does not support C based modules directly, you would have to
write a wrapper for your DLL in C# (or another .NET language) and have it
used from there.

When you say it works in other languages, what do you mean?

Thanks,

slide
