title: Windows Phone VB "NavigationService is not declared"
body: <p>Im creating a very simple Windows Phone 8.1 app in Visual Studio Express. I have added a Hyperlink control, then from that I have double click to go to the relevant VB page. </p>
  
  <p>As instructed by the many tutorials out there I have added the code for the button - which should navigate it to the second page I have created.</p>
  
  <pre><code>Private Sub hyperlinkButton_Click(ByVal sender As Object, ByVal e As RoutedEventArgs)
      NavigationService.Navigate(New Uri("/SecondPage.xaml", UriKind.Relative))
  End Sub
  </code></pre>
  
  <p>However VB keeps on giving me the error "NavigationService is not declared"</p>
  
  <p>Searching the error message has given me very little joy so far.</p>
