Notification Activation Flow

Local app notifications require content, manifest activation, registration, and app-side routing.

Flow

Button click
  -> AppNotificationBuilder creates payload
  -> AppNotificationManager.Show displays notification
  -> User clicks notification
  -> Windows activates app through manifest/COM registration
  -> App registers notification manager
  -> App reads activation args
  -> App chooses foreground UI or silent action

Startup Order

_window = new MainWindow();

AppNotificationManager.Default.NotificationInvoked += OnNotificationInvoked;
AppNotificationManager.Default.Register();

var activatedArgs = AppInstance.GetCurrent().GetActivatedEventArgs();

The official quickstart calls out that Register must happen before GetActivatedEventArgs.
