Having spent some time kicking around the Delphi space I got quite into WPF in 2007ish. By 2010 I had not just sworn off it, I'd sworn off Windows entirely. The constant stream of rug-pulls as one bit of MS managed to pull off a political heist over another and - oh no - yet another "latest and greatest" technology was effectively deprecated within 18 months of launch, invalidating all the effort you put in to staying up to date just became a pointless treadmill.
Fortunately Rails was taking off at that point so it was fairly easy to change horses and just ignore it.
Microsoft had a lot of great talent suffering from a lack of leadership and coherent vision. They foreshadowed everything wrong with Big Tech today.
At the same time VB still works and runs, so they don't always rug pull.
If I'm writing Windows desktop GUIs I still stick to WPF. Might be Stockholm syndrome but I quite like it.
I don't see the reason to use any of the new ms ui frameworks. Especially if ms themselves don't even really use them.
As far as I know visual studio is still a WPF project so I'm not super worried about it no longer working.
