It is clear that it is not possible to reference .Net Standard 2.1 or .Net Core 3.0 in .NET Framework 4.8 project. If I add a .Net 4.8 class library into my .Net Core 3.0 project it seems to work. My .Net Core WPF application seems OK.
I am trying to figure out if any side effects may arise. I could not get a clear result. The question is that should I reference .Net 4.8 in my .Net core 3.0 app or not?
