Windows Phone 7: No forward navigation

Information forward navigation at Windows Phone 7:

Navigation Stack on Windows Phone 7 - Peter Foot - APPA Mundi

“While Windows Phone uses the same NavigationService and page-based model as “regular” Silverlight, one area the documentation doesn’t make clear is that although the APIs seem to support both Back and Forward navigation in reality there is no forward navigation on Windows Phone. This means when you navigate to a new page and then return Back to the previous page you can’t call NavigationService.GoForward() to return. CanGoForward will always return False. In the documentation for System.Windows.Controls.Frame (the base class of PhoneApplicationFrame) GoForward is described as:-

“Navigates to the most recent entry in the forward navigation history, or throws an exception if no entry exists in forward navigation. For Windows Phone this method will always throw an exception because there is no forward navigation stack.”
