How do I clear navigation history in Silverlight/Windows Phone 7?

Question

I\'m making a Windows Phone 7 app that has login/logout semantics (authenticating to a web app). When the user logs out I navigate back to the login screen and forget the sessio

This code works well (it needs to be in your page), haven't tried to get it past certification yet but the code does work:

 while (true)
 {
     if (this.RemoveBackEntry() == null)
     {
         break;
     }
  }

This does seem to differ with the documentation, which says an exception will be raised when there is no more items so I have logged a bug on user voice for this, so it may change in future.
