I update in the repository to .NET 7, mostly it was mundane work, but something changed in Settings handling in between .NET 5 and .NET 7, so if you raise an issue in https://github.com/kant2002/WinFormsComInterop I can take a look more closely and fix this specific project. Other project looks should be update. If not, let me know, I'm definitely would like to make things working to it's fullest. This is related to some types was trimmed out. I have to figure out which one.
