NavigationService.Navigate(new Uri("/Pages/MyPage.xaml", UriKind.Relative));
NavigationService.Navigate(new Uri("/Pages/MyPage.xaml?id=3&category=books", UriKind.Relative));In this example, the current page would navigate to the same "MyPage.xaml" as in Example 1 but with query parameters appended to the end of the URI. In this case, the parameters are "id=3" and "category=books". These parameters could be used in the MyPage.xaml page to display specific content based on those values. The package library for the PhoneApplicationFrame Navigate method is part of the Windows.Phone.UI.Xaml.Navigation namespace, which is included in the Windows Phone SDK.
