[IronPython] clr.AddReferenceToFile bug?

[Lukas Cenovsky]

Hi all,
I thought clr.AddReferenceToFile should behave similarly to 
clr.AddReferenceToFileAndPath when I adjust sys.path manually first. But 
it seems they don't. Is it a bug or feature?

This works:

import clr
import sys
clr.AddReferenceToFileAndPath('..\\PythonModules.dll')

This does not work:

import clr
import sys
sys.path.insert(0, '..\\')
clr.AddReferenceToFile('PythonModules.dll')

Traceback (most recent call last):
