title: Set start page in Windows Phone 8.1 universal app
body: <p>I need to change start page in my app depending on logged user or not. In Silverlight 8.1 version all what I need to do is delete starting page in manifest file and in App.xaml.cs:</p>
  
  <pre><code>private void Application_Launching(object sender, LaunchingEventArgs e)
          {
              Uri uriMain = new Uri("/PivotPage.xaml", UriKind.Relative);
              Uri uriLogin = new Uri("/MainPage.xaml", UriKind.Relative);
  
              var settings = IsolatedStorageSettings.ApplicationSettings;
              if (!settings.Contains("user_id"))
                  {
                      RootFrame.Navigate(uriLogin);
                  }
              else
              {
                  RootFrame.Navigate(uriMain);
              }  
          }
  </code></pre>
  
  <p>But in universal version I can't figure out how can I do it. What I need to do to achive this in WP 8.1universal app?</p>
