what is this window.Closing += Window_Closing;

I think you ask about window closing event.This event will fire if close the current window means at the time we can call any function.
Refer this link you get an idea..

Hi

Window.Closing event is fired just before the window is closed.
As a CancelEventHandler it has the provision to stop the closing by writing e.Cancel=true.

This event is used when you want to do some operation ( either saome validation or save etc. you ask for a confimation aslo before closing ) just before closing a window form.

Please take a look at this
