The thing about especially some of the more recent efforts is: the approach might have made sense when Microsoft was a monopoly and there was lots of interest writing software for Windows. But suddenly targeting Windows is much less interesting, but they still have the monopolist's arrogance: "You will rewrite your app to work on our new UI framework, right? Right...?" What actually happens is that every deprecation and every new thing weakens their ecosystem. Their biggest draw is in legacy software, and they variously want to throw out their legacy support, or create tomorrow's legacy today with new frameworks that end up abandoned.
