cannot get anymore int of enumclass (alpha2) #1810
Description
Environment
- Pythonnet version: 3.0.0dev
- Python version: 3.9
- Operating System: Windows
- .NET Runtime:
Details
- Describe what you were trying to get done.
In v2.5.2 I'm able to get a C# enum and get the int value. In alpha 2 it seems that the full enum class is returned but the int command is not working. In 3.0.0dev it makes crashing the Debugger.

I can't reproduce this, you have given almost no code here. Does the code run outside of the debugger? Please provide a Minimal, Complete and Verifiable example.

Hi @filmor I don't know how to create an example for you since I obtain it from My C# API that returns an enum on the following call:
self.edbcomponent.GetComponentType()
I have the full enum in it including .value__ property (not .value). When I do the int of that enum it crashes and and stops to work. It fails also in running mode.
This is the content of the enum
the command should return 1 (the content of value__)

I am sorry, I can't and won't do remote debugging. Please provide a complete example that reproduces the issue that I can run on my machine.

Taken from your Unit Test:
from System import DayOfWeek
int(DayOfWeek.Sunday)

Odd that this works in the unit test itself, I'll have a look.
maxcapodi78 commentedon Jun 8, 2022
@filmor I've taken from UT the enum to test but I noticed that you don't run a test on an enum value.
So you can debug and add that as additional test for future reference

The exception looks like GIL is being released somewhere.

@maxcapodi78 This should be fixed on the current master, if not, please reopen :)

@filmor I've tested the latest main and it works pretty well. Thanks
