Actually its not that easy, depending which parts of framework you used. It's certainly reasonable, but will take re-work for many applications beyond the project structure migration. I think in .NET 6/7/8 the .NET framework migration situation will improve to be mostly pure migration. For example I migrated about 75% of a moderately large winforms system directly, but 25% needed rewrites due to missing core implementations for framework libraries. e.g. MS chart component not implemented in core yet, soap services changing to grpc, and various others. And this system was originally built to minimise third party dependencies and use the core framework or microsoft provided libraries wherever possible.
