One of the issues I ran into when I looked at porting to .net core 3 was the crypto library. They didn't implement all .net framework classes, the ones related to public/private keys in particular. Perhaps they do now. I don't know how many edge cases I will find like that.

On the recreating project files, I don't think you can copy-paste winform code like that, you need to recreate it using the UI, which is a pain. Also they had this weird concept that an assembly had to be set to be a "winform" or "wpf" assembly, you couldn't simply reference system.windows.forms, which basically prevented you from creating a helper winform assembly, and you certainly couldn't create an assembly that referenced both winforms and wpf DLLs. They perhaps also fixed that since.

In any case, it's not a complete rewrite to migrate to .net 6, but it is far far from a simple lift and shift.
