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

Hi Guys, I was wondering if anyone knows how to make Python for .Net work on cygwin installation of python. I have been looking around and find a mixed bag of information. If anyone knows of the working version of Python for .Net and its dependency, I would appreciate if you could share it with me. Currently, I am using a generic windows version and it works just fine, but I need it to work on Cygwin version of python. I appreciate any helpful replies. Thanks, Nikhil

cx_freeze and python.net
by Boris Burdin May 22, 2017

May 22, 2017

Hello everybody, I'm trying to build a python.net application using cx-freeze . Once the application is built, I put in my final folder the Python.Runtime.dll. but it stil doesn't seem to work . Actually, when I run the .exe file, nothing is happening. So, I wonder if there were something else to do, another dll to put in the folder, or any option to use with cx_freeze when building the application ? i would be very grateful if you could help me on this matter .. Thanks in advance, Boris

pythonnet appdomain(s)
by Adam Klein Sept. 7, 2016

Sept. 7, 2016

Hello, Is there a design reason that pythonnet loads C# assemblies into its own AppDomain rather than establishing a separate AppDomain? It would be useful for instance when developing in C# in parallel with writing python code (say, in the ipython REPL) to be able to reload C# assemblies dynamically. Also, we've found it useful in Initialize() to enable shadow copying, to prevent file locking, ie internal static void Initialize() { ... AppDomain domain = AppDomain.CurrentDomain; // prevent file locking domain.SetShadowCopyFiles(); domain.SetShadowCopyPath(null); Although these are deprecated methods, and really it should be establishing a new AppDomain as above.

Does python .net support creating a class inherited from an interface class declared by c#?
by Oscar Le April 21, 2015

April 21, 2015

Hi There, I want to create a class which can be inherited from an interface class declared by c#. But it throws TypeError when I instance it: "object does not implement IServiceCallbackContract". class ServiceCallbackContract(IServiceCallbackContract): def __init__(self, c): pass object = ServiceCallbackContract(AClass) Then I added some debug messages in the Python.Net source code. [cid:image001.png@01D07C84.4EA703C0] I mean I want to create a class as the implementation of the interface class which is declared by C# in a DLL file, I'm unable to change the code in that DLL file. So is there any way to make it works for my purpose by python.net? Thanks, Best regards, Oscar Le
