Board
Board.Core.BoardApplication
BoardApplication.Exit() Method
Exits the application. Functions similar to swiping the application away from the Recent Apps screen. This is a fire-and-forget operation; the app will be terminated immediately and cannot receive a response.
public static void Exit();
Remarks
This method cleanly closes the app by removing its task from the system. All activity lifecycle callbacks will be properly triggered. Use this when you need to programmatically exit the application.
