@filmor do we even need
Shutdownon .NET Core?filmor commentedon Sep 23, 2023
We need to call
Shutdown(in my opinion) just as well to ensure that destructors run in a sensible order. What we definitely don't need to do is the stashing part. It only needs to run if we want to reload domains, which is not supported on .NET Core anyway. I'm currently working on this (and related slowness during shutdowns) here:#2245

I recently tried pythonnet in C# Console Application in Visual Studio 2022.
Environment
For now,
Shutdownis needed, because without it, one of the threads does not allow the process to end completely.Then I tried to call
Shutdownbut got this exception in the PR.In this case, need to add
<EnableUnsafeBinaryFormatterSerialization>true</EnableUnsafeBinaryFormatterSerialization>to the project file. Even with this flag, the process does not terminate withoutShutdown.And after this flag and call
Shutdownthe process ends correctly.filmor commentedon Sep 19, 2024
This should be fixed now.
