title: Override default ClickOnce splash screen with a custom one
body: <p>I have a C# application that uses the ClickOnce distribution method.  ClickOnce automatically checks for a new versions, and if it is available, downloads and installs it on the customer's machine.</p>
  
  <p>My own application has a slash screen, this results in there being two different "splash" screens seen by the user (click once auto-update, and my splash screen).</p>
  
  <p>Is there a way I can override the default ClickOnce auto update screen with my custom splash screen?</p>
