The problem is it leaves all .net framework code on a dead-end platform. For all previous .net versions, code could be easily and safely upgraded to the next version because they were largely backwards compatible. But you can't easily upgrade existing code from 4.8 to 5.

If you want to start a project from scratch, sure Core/5 is nice.

As someone who has been working with .NET since the first release: tell me about it! I fully concur. I don't deny this, nor excuse it.

That said, I believe that once Microsoft decided that it was OK to break compatibility, they managed to improve upon lots of things which up until that point had become fairly painful on the traditional .NET Framework.

You win some, you lose some, I guess?

Business logic ports over really well - we have been able to effectively copy and paste code and the corresponding tests between a legacy .NET Framework WinForms app and .NET Core 2.0 and later service (WebAPI or gRPC) and it mostly just works. The trouble comes when the code integrates heavily with a UI stack - that’s a lot more work to port over. It was pretty hard before .NET core 2 though. But .NET 4.8 will be supported as long as Windows 10 is - probably at least another 10 years or more.
