Multithreading/multiprocessing
by Alan Macdonald May 5, 2025

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

Support for Python v3.9
by Douglas Wyant (Aptly Technology Corporation) July 22, 2021

PythonNet, Hi folks, I have no idea if this is the correct way to engage support / ask questions, so please redirect me. We need to deploy Python v3.9 to resolve a known Security issue in older versions. I'm told we're blocked on deploying until PythonNet is updated to support v3.9. So the question is when might that be? https://bugs.python.org/issue41944 CVE-2020-27619: WIndows Python versions 3.0.0 through 3.9.0 are susceptible to a vulnerability which when successfully exploited could lead to disclosure of sensitive information, addition or modification of data, or Denial of Service (DoS). Affected Versions Python versions 3.0.0 through 3.9.0 Thanks, Doug Wyant (Aptly Technology Corporation), GSEC, GCIH Service Engineer 2 Microsoft
