Also, if the main window is to be closed by the user, the program shouldn't be displaying in the Task Manager Processes.
So, after several steps and changing of codes, I finally got the answered. In order to be sure: I executed these two steps:
1. As I've said, if the x button in the splashscreen is clicked, the whole program is killed! --- CHECKED!
2. If the Main Window is closed (X button is clicked), the whole program should also be killed! --- CHECKED!
1. Go to App.xaml, set your shutdownmode: (note that my StartupUri is set to my SplashScreen)
2. In your MainWindow XAML, add this:
3. Finally, make a closing handle event in your MainWindow.xaml.cs
private void Window_Closing(object sender, System.ComponentModel.CancelEventArgs e)
private void Window_Closed(object sender, EventArgs e)
There are lots of ways to solve this, I know :). In order to be sure and avoid more debugging, I just doubled my event handlers. The Window_Closing and the Window_Closed.
