.NET is a terrible technology; it was bad 10 years ago, and nothing changed since. .NET has countless versions, it generates some esoteric errors, I spent the whole day trying to figure out an esoteric, seemingly stupid, yet easy to fix issue and I literally cannot sleep. I have no idea why it is not working. Nothing gives me a good answer, chatgpt google just repeats word by word the error, you did not specified the .net version in the project file, I checked the file it is here…. never mind. TLDR; run away from .NET terrible technology
