Closing Your Application
WPF
A common way to close the application is to use the following command:
Application.Current.Shutdown();
However, although your main form will close, this can sometimes leave remnants (e.g. processes) running in the background. If this is happening, I have found that the following way exits everything:
// The parameter is an exit code, use 0 if you// are not concerned about this.Environment.Exit(0);
