I'm still wondering whether it would be smart for them to port WPF or UWP to all platforms. They are already decoupling their services from Windows and a UI library would be quite a flagship for them.

Then again they'd also lose the Windows vendor lock-in, which might still be more valuable to them.

Then again they could sell their development toolchain and gain developer sympathy.

Well, I think it is an engineering problem. WPF is basically cemented to DirectX which only exists on Windows.
