[ACCEPTED]-How to override onclose event on WPF?-wpf

Accepted answer
Score: 18

The application never closes because you 1 are setting e.Cancel to true.

Try

protected override void OnClosing(System.ComponentModel.CancelEventArgs e)
{
       //do my stuff before closing

       base.OnClosing(e);       
}

You are asking it not to close by setting 1 e.Cancel = true. Just don't do that.
