[Python.NET] Problem installing pythonnet 2.5.2 on Debian 11

Hello , I am developing with Python 3.7.9 on Debian 11 and I have to import C# Libraries. For that I’ve tried to install pythonnet 2.5.2 via pip, but I get error messages. I’ve installed clang, libglib2.0-dev, nuget, dotnet runtime 2.0 (the C# Libs were developed with .NET Core 2.0, but I tried also 6.0 without success). So, how I have to install pythonnet 2.5.2? Thanks for your help! Best Regards, Muhammed-Talha Özmen
