AudioGraphBackgroundPlayback.App.CreateRootFrame C# (CSharp) Method

CreateRootFrame() public method

Creates the frame containing the view
This is the same code that was in OnLaunched() initially. It is moved to a separate method so the view can be restored when leaving the background if it was unloaded when the app entered the background.
public CreateRootFrame ( ApplicationExecutionState previousExecutionState, string arguments ) : void
