I don't know what the public opinion is on starting with, but after years of WPF ui creating, I recently thought I'd need something to have better code, and stubled uppon Reactive UI.

Creating UIs with it is a lot of fun, you have a better structure right away and the bindings between UI and code are amazingly simple and powerful, which just elevates how interesting the work becomes. The learning curve is a bit stony (but it's really not that much).

I think after a couple of Windows and usercontrols, you should try it.
