I got it working with the latest C2 update, but my game is really simple and yet it's running a little slow... I'm thinking it's because I'm running it in debug but I'm not sure how to install it to the console so I can test it? There's a "Games & Apps" bar on the Dev Home app, but it says there are no installed games there. Is there a way to install the game so I can test it directly from the Xbox?
Edit: Nevermind, I figured it out. Once you run the game from your PC, it is installed on the Xbox One main menu so you can run it directly from there without having to build it again.
I'm impressed, it's running great!
