Tracking Active Notifications

INotificationService service = /* from DI */;
INotificationEventService events = /* from DI */;

// Show returns the notification ID
Guid id = service.Show(NotificationBuilder
    .Create("Tracked", "This notification is tracked")
    .AsInformation()
    .Build());

// Dismiss by ID
service.Dismiss(id);

// Or dismiss all
service.DismissAll();
