[Ironpython-users] Using pyc.py get import error on minimal WPF app

[Chaim Krause]

If I copy the dll into the same directory as the exe AND modify the 
code to...

import clr
clr.AddReferenceToFileAndPath("IronPython.Wpf.dll")
import  wpf

THEN it works. So, yes. It appears that something is wrong with the 
import.

Has anybody else experienced this with the latest beta?

Can somebody else on the list who hasn't moved to the beta test this 
and see if it is a regression or has existed in prior versions?

With you input I will open/update a bug on this topic.
