Need help to hide Navigation Bar in WP8.1

Navigation bar overlaps bottom part of game screen in Windows Phone 8.1. I use monogame 3.3.

See this issue on GitHub. The soft navigation bar is not entirely under app control. If the user does not have auto-hide enabled in the phone settings, then it will always remain visible. Direct3D apps will always use the full screen size, including the area underneath the nav bar.

Thanks a lot! It’s useful for me!
