How to delete file, then user closes program in WPF?

I know full path of file var temp_file = Path.Combine(_directoryName1, "temp.ini"); which need to be deleted in the end of program working. How could I do this ? As I know it is possible to realize via OncloseEvent(). In addition, I dont know exatly how user will close application via alt+f4 or via buttons.

So far, I have tried to use this code below from almost the same question How to override onclose event on WPF?

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

       base.OnClosing(e);        
}

And I have added it in App.xaml.cs but it doesn't work. VS2013 says that he don't know such method base.OnClosing(e);

Is there any mistake or another way out?

Window.Closing is for a specific Window. That's probably not what you want in any case, because the Closing event can be cancelled. Window.Closed is likely a better choice.

To run something when the program is closed -- not tying yourself to a window -- you should subscribe to the Application.Exit event instead.
