I am trying to use pythonnet package in a VSIX Visual Studio extension.
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);
}
[INFO] - PythonEngine: Initializing Python engine. [ERROR]: Object reference not set to an instance of an object.

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, |
