The flavor-of-the-day is UAP/UWP, which actually has awesome APIs. The only problem is that it's Windows 10+ and can't make universal or standalone binaries.
UWP also is like Silverlight more so in that it is missing a lot of stuff from the original WPF, you have to basically relearn it. However, Win2D is pretty good, nice performance.
Two different meanings of the word. I meant a single binary that can run on multiple versions of Windows. They mean universal as in one codebase that will deploy to PC, phone, and Xbox.
