No. There is a list of supported events and a device reset is none of them. And IMHO: Even if you'd be able to listen for such an event - it would be the wrong way.
If you have important data to backup:
Do it when your app gets suspended! When the suspension is triggered you have around 10 seconds to backup important data.
Application.Current.Suspending += new SuspendingEventHandler(App_Suspending);
async void App_Suspending(
Object sender,
Windows.ApplicationModel.SuspendingEventArgs e)
{
// TODO: This is the time to save app data in case the process is terminated
}
Just save it to the roaming data storage or folder and you will be able to use it again after a reset.
It's fairly easy and requires only a few lines of code:
