See the links I listed above. None of those features solved a language problem as large as the lack of sum types. It baffles me that they even spent time on them before providing a feature that is in such high demand (and has been for more than a decade).

I understand that you shouldn’t always give users what they ask for - but this is something that has picked up steam in other languages because it’s actually useful and makes code bases easier to maintain.

You're projecting your strong opinion on others.

I've used C# since 2008 for business software and high performance computing. I've not missed sum types at all. Most of what was added is something I see a lot of value in. I don't like that it, by design, obsoletes some older parts of the language, but that's about it.

I'm now using C# on linux almost exclusively. No complaints from me!
