title: Xamarin Forms Orientation on iPad
body: <p>I have a Universal Xamarin Forms App with a single page wrapped in a NavigationPage:</p>
  
  <pre><code>Current.MainPage = new NavigationPage(new RootPage()
              {
                  BackgroundColor = (Color)Application.Current.Resources["BackgroundColour"]
              })
              {
                  BackgroundColor = (Color)Application.Current.Resources["BackgroundColour"],
                  BarBackgroundColor = (Color)Application.Current.Resources["BackgroundColour"],
                  Padding = NavigationPaddingForPlatfrom()
              };
  </code></pre>
  
  <p>I've also overridden GetSupportedInterfaceOrientations in AppDelegate and set a break point - however the break point is never hit.  When I rotate in the simulator or device, the break point isn't hit.  I've also set the Device Orientation in info.plist to Portrait only, however the App still rotates.</p>
  
  <p>Am I missing some configuration point that's needed to control orientation?</p>
  
  <p>I'm using Xamarin Forms 2.4.0.38779.</p>
  
  <p>The end goal is to force a MasterDetail Page into landscape only.</p>
