[Python.NET] Python, the CLR and System.Security?

[michael_sweeney at agilent.com]

Hi,

I am trying to integrate NUnit with our current automated test tool. 

I copied the two PythonNet dlls, Python.Runtime.dll and CLR.dll, into
the ActiveState Python 2.3 directory.

When I try to run my wrapper module, ATFAdaptor.cs, which is a stripped
down/modified version of the ConsoleUi.cs file, I receive the following
CLR Exception:


ex.Message:

Request for the permission of type
System.Security.Permissions.FileIOPermission, mscorlib,
Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089
failed.

ex.Stacktrace:

It looks like the regular CPython version has some sort of permission
problems interacting between managed code and python. 

Is this something I can work around, or fix? 

Also, if I run the wrapper module with the PythonNET version of the
python.exe, the wrapper can execute the NUnit test, but hangs
afterwards.


Thanks in advance...
