Which .NET version for Add-Ins does Inventor 2023 support?

[verena_liewaldMU2Q9]

I have some problems upgrading my C# Inventor Add-In (with my own Ribbon Tabs etc.) from .NET 4.8 to .NET 6. I am using Inventor 2023. Looking up in the Inventor.exe.config, I found .NET 4.8. Does that mean that .NET 6 is not possible to use? Or can I manually manipulate this file?

In the conversation  Inventor .NET 6 Add-In (.NET Core followup version) - Autodesk Community - Inventor

I found some issues about Inventor.Documents (@Andrew.WhiteBEDAD). Is that still a problem? 

Thank you for your help.
