title: Is Win 10 (UWP) development like Win 8.1, WPF, or both?
body: <p>I just upgraded to win 10, and I have a book for win 8.1 app development (which I have yet to start); I'm aware of a few perks to win 8.1 apps over WPF, and I'm wondering if the new WPF (if it is new beyond aesthetically) has these perks? Is there any reason to read this 8.1 book? Or are there large changes that I should just get a win 10 book?</p>
