Multithreading/multiprocessing
by Alan Macdonald May 5, 2025

Hello, has anyone successfully used multithreading or multiprocessing with Python.Net? I tried to multi-thread from the .Net side and the Python.Net libraries seem to have issues in the RunScript method. I had to take an implementation off the web of that method because the shipped method doesn’t seem to work. I then had a working multi-processing example from CPython that I tried from Python.Net but it gives an error 'module' object has no attribute 'argv' When trying to create a process pool by executing the line pool = Pool(processes=4) Is it possible to do multithreading or multiprocessing with Python.Net? Thanks, Alan

WPF and XAML
by Min Kim April 28, 2014

Python for .Net does not seem to support development of UIs in WPF/XAML. Google search shows one question several years ago but without reply. Is there a trick to making it work or is it in the "to be implemented" list? Thanks.

Deprecation warnings

I just upgraded to pythonnet 2.0 - thanks to "pip install -pre pythonnet" Thanks for making that work. I am now getting these deprecation warnings: The module was found, but not in a referenced namespace. Implicit loading is deprecated. Please use clr.AddReference("System.Collections.Generic.List"). from System.Collections.Generic import List When I try suppressing this as suggested I get an error due to being unable to find the System.Collections.Generic.List assembly. Wondering how we are supposed to handle this in the future? John PS anyone heading to PyCon?

Hi there, I'm trying to use Python for .NET in my Winforms C# app, but when I call PythonEngine.Initialize() I get an error about not being able to find python27.dll. I searched all over the place, but I actually don't see any python27.dll... Any ideas? - Lutz
