退出Windows 8.1应用时执行代码

Question

I'm attempting to execute some code on my Windows 8.1 app on exit, when a user drags the app down normally (not the extended hold to terminate).

In Windows 8, I used the following code to clear the app's tile on exit:-

    private async void OnSuspending(object sender, SuspendingEventArgs e)
    {
        Windows.UI.Notifications.TileUpdateManager.CreateTileUpdaterForApplication().Clear();
    }

However, this code isn't called in Windows 8.1 when the way the app terminate changes.

How do I recreate my code for Windows 8.1?

In 8.1, the close gesture no longer kills the app. Instead you have to hold it at the button for 1 second and when the icons flips , the app is closed.

Look if the code is executed there.
