问题 I'm investigating building a "Game Capture" App that works within UWP on Xbox One, as for capturing the actual content of the screen during game-play, it appears there are two ways to go within the wider eco-system of Microsoft libraries: DirectX (Now part of Windows API) Microsoft Media Foundation With that in mind, my assumption is that DirectX is natively accessible by UWP apps via the Windows Runtime API, and aside from limitations on the DirectX feature-sets and hardware, basic APIs

问题 I am making a Universal app. For the windows phone part I have implemented a pivot page in it.
