.NET is now cross platform, but only as long as it doesn't hurt VS sales - I think MSFT doesn't care just as they don't care about GUI workloads, because only thing they care now is having developers run their stuff on Azure. You don't need VS for those cloud .NET apps and you don't need front end frameworks like Forms, Xamarin or MAUI. Seems like C++ is also something they would not be interested investing into when they can get people into cloud easier with C#.
