I see that you can close an App by grabbing the top of the screen and pulling downward but I do not see how I can do this through programming. I want to add a close button (app has sensitive data I want it to shut down). I see no methods in the Application to do this.
Maybe I just hide the data on the screen instead for security. Windows 8 store apps big technical advances are you have a harder time finding an app to launch/start and then you have the same difficulty in stopping/closing it. I don't understand why they did this.
