问题 I would like to create a UWP app (XAML) with C++/CX and DirectX 12 so that I can mix both XAML controls (things like Grid, buttons...) and DirectX, something like a Level Editor, but I'm struggling to find a way how to initialize DirectX to render inside a specific control (like a Grid).

问题 I have a UWP app that requires the restricted capability "broadFileAccess" to access data from a file. I also have to use "runFullTrust" capability for registry access.
