title: Suppress System Overlays, Windows phone 8.1 (Silverlight)
body: <p>I wanted to know how to hide the navigation-bar.
  And if it is possible to specify in XAML the code to <code>SuppressSystemOverlay</code>, as it is with the systemtray : <code>shell:SystemTray.IsVisible="False"</code>.</p>
  
  <p>I cannot find the description not even on <a href="https://msdn.microsoft.com/en-us/library/windows/apps/xaml/windows.ui.viewmanagement.applicationview.suppresssystemoverlays.aspx" rel="noreferrer">msdn</a>, which seems to refer to wp 8.1 build with WinRT, and my application is with silverlight.</p>
