I did, and while UWP seems still a bit immature it sure is nice. Unfortunately I have a couple of existing and pretty huge WPF apps and it does not seem you can 'port' that to UWP in some way (except like rewriting all UI code - or am I missing something?) so I don't think I'm gonna switch anytime soon and I'm probably not alone?
Yea unfortunately the new XAML isn't 100% compatible with the old XAML. Things like DataTriggers no longer exist; everything is Visual State Manager. On the plus side, though, UWP XAML perf is significantly better than WPF XAML.
WPF is still supported however, and recently got improvements in .Net 4.6. There are plans to allow WPF apps (and other Win32-based apps) to be published on the Windows Store, so you might not have to worry about porting, as long as you're happy just targeting PC users.
