title: Action Center Toast Notification without Shortcut
body: <p>I've created a custom C#/WPF application that can send toast notifications that has an activator that can handle activation.  I'm using WiX to deploy the solution and create a shortcut with ShortcutProperty elements for System.AppUserModel.ID and System.AppUserModel.ToastActivatorCLSID.</p>
  
  <p>Everything works perfectly as expected but I wonder one thing.  Is it possible to register the ToastActivator without creating a shortcut?  This program is going to be used on an internal enterprise network and I don't intend for it to have any UI.  It'll be launched by the Task Scheduler, check a web service and send toast messages to the user when they apply.</p>
  
  <p>If I must have a shortcut, the best UX I can think of is to just diplay an about dialog and exit.</p>
