Uh oh!
There was an error while loading. Please reload this page.
Environment
- Pythonnet version: 3.0.3, 3.1.0
- Python version: 3.09
- Operating System: Win11
- .NET Runtime: 4.8
Details
- Describe what you were trying to get done.
I am trying to use pythonnet package in a VSIX Visual Studio extension.
The Experimental VS Instance initializes pythonnet fine, however deploying an extension causes this crash.
I suspect there may be some threading issues, but am not sure what to look for.
try
{
Runtime.PythonDLL = pythonFile.FullName;
PythonEngine.PythonHome = pythonFile.DirectoryName!;
OutputWindowHelper.LogInfo("PythonEngine", "Initializing Python engine.");
PythonEngine.Initialize(); // crash here
PythonEngine.BeginAllowThreads();
}
catch (Exception ex)
{
OutputWindowHelper.LogError(ex);
}
- If there was a crash, please include the traceback here.

Why you close my issue?
Here's your fix:
internal static bool ShouldBindEvent(EventInfo ei)
{
var mb = ei.GetAddMethod(true);
if (mb == null)
{
return false;
}
return ShouldBindMethod(mb);
}
Check your nulls, thank me later.

Hello ,
I have the same issue, I am trying to use pythonnet package in a VSIX Visual Studio extension.
I am going to apply this fix above made by @cpgames and see if the problem persists.
Do you intend to release this fix in a future version of pythonnet ?
Regards,
