C# – How to exit a WPF application programmatically


In the few years I've been using C# (Windows Forms), I've never used WPF. But, now I love WPF, but I don't know how I am supposed to exit my application when the user clicks on the Exit menu item from the File menu.

Best Solution

To exit your application you can call


As described in the documentation to the Application.Shutdown method you can also modify the shutdown behavior of your application by specifying a ShutdownMode:

Shutdown is implicitly called by Windows Presentation Foundation (WPF) in the following situations:

  • When ShutdownMode is set to OnLastWindowClose.
  • When the ShutdownMode is set to OnMainWindowClose.
  • When a user ends a session and the SessionEnding event is either unhandled, or handled without cancellation.

Please also note that Application.Current.Shutdown(); may only be called from the thread that created the Application object, i.e. normally the main thread.
