title: Navigation between pages in WPF?
body: <p>I have my WPF application and my button is on a WINDOW that I added and I want the button to open a PAGE when I click it.</p>
  
  <pre><code>NavigationService nav = NavigationService.GetNavigationService(this); 
  nav.Navigate(new Uri("xamlFeedbackPage.xaml", UriKind.RelativeOrAbsolute));
  </code></pre>
  
  <p>I have tried that code that was online and my application crashes when I click the button.</p>
