When they announced UWP I was just starting a new side project and I thought, let's check it out. I was hoping it would basically bring WPF into first class citizen territory. Instead, they made them needlessly incompatible. Like writing for both NeXT and MacOS, but on the same platform. I got discouraged right away and have really never done any significant Windows work since, which turned out to be a great move for my sanity.

Ahhm. At previous $DAYJOB, I inherited a WPF app written in 2012; I stumbled upon several WONTFIX bugs through the years - mostly having to do with shared memory bitmaps, having to manually call GC at times, and a host of other things.

Stable, but many issues. Stay away if you value your sanity and do anything nontrivial.

the should just have updated wpf with their newer widgets and just continue to improve it and even make it cross platform. (basically what avalonia is doing)
