title: Handling suspend, resume, and activation in windows 10 UWP
body: <p>In the windows 8.1 universal apps, the suspend/resume modes were handled using the <code>NavigationHelper.cs</code> ans <code>SuspensionManager.cs</code> classes included in the APP template. These classes doesn't seem to be there in the windows 10 UWP apps. Is there a way by which we can handle the suspend/resume states?</p>
