The NotificationService allows you to display popup notifications in your applications. You can use the native Windows 8/10 look & feel or create a custom template.

Expanded Create Windows 8/10 Native Notification

To display a Windows 8/10 native notification, specify the following NotificationService properties:

Place the NotificationService into the Interaction.Behaviors collection and define your View Model's NotificationService as a POCO object.


When View Model is inherited from the ViewModelBase, use the Services in ViewModelBase descendants topic approach.

Expanded Create a Custom Notification

The NotificationService uses its own notification mechanism to create a custom notification.

Use the NotificationService.CustomNotificationTemplate property to define a custom notification layout.

To create a custom notification, use the NotificationService.CreateCustomNotification method. This method requires a notification's View Model as a parameter.

Use the INotification.ShowAsync method to display the created notification. This method returns a NotificationResult enumeration value depending on how the notification is displayed and which notification element an end user clicks. The ShowAsync method returns the following values depending on the notification result:

  • Activated, if a user clicks the notification.
  • UserCanceled, if a user clicks the notification's close button.
  • TimedOut, if a user does not click the notification during the time specified in the NotificationService.CustomNotificationDuration or NotificationService.PredefinedNotificationDuration property.
  • ApplicationHidden, if you use the INotification.Hide method when the notification is displayed.
  • Dropped, if the system's notification queue is full and the notification cannot be displayed.

The code snippet below illustrates how to process the ShowAsync method's result.
