Remarks

A chat app must register a background task to process notifications in order to serve as the default handler for incoming messages. In order to register a background task, the Package.appxmanifest file must contain a background task extension. Add the following code snippet into the Application/Extensions element.

<Extension Category="windows.backgroundTasks" Entry-Point="Tasks.ExampleBackgroundTask">
    <BackgroundTasks>
        <Task Type="chatMessageNotification"/>
        <Task Type="systemEvent"/>
    </BackgroundTasks>
</Extension>

The background task's Run method receives a task instance with the notification trigger details. The TriggerDetails property is cast to a ChatMessageNotificationTriggerDetails object. The trigger details for a chat message are obtained as shown in the following example.

public void Run(IBackgroundTaskInstance taskInstance)
{
    BackgroundTaskDeferral deferral = taskInstance.GetDeferral();
    ChatMessageNotificationTriggerDetails triggerDetails =
        (ChatMessageNotificationTriggerDetails) taskInstance.TriggerDetails;

    if (triggerDetails != null)
    {
        SendToast(triggerDetails.ChatMessage);
    }
}
