    // Restart app in safe mode to avoid another initialization failure.
    // Note: Your app would need to handle the 'safemode' argument and
    //       implement a safe mode experience in this scenario.
    AppRestartFailureReason reason = AppInstance.Restart("/safemode");
    switch (reason)
    {
