I'd add that WPF was "don't bother" up until recently when WPF support was added. (Though I don't know if that means stock WPF or that it supports the breadth of WPF controls out there, and whether it requires WPF component vendors to make changes)

We just migrated our massive WPF application to .NET 8 and there are a handful of libraries that are not supported or had to be replaced but overall it was surprisingly smooth. The biggest issue we have is that garbage collection seems to have taken a huge hit and there are bugs in the Microsoft WPF components (any sort of list view in particular) but it's all relatively easy to work around.
