Toast notifications c#

Question

Hello, How can I use Azure to notify the user that you have new content in the app? I am creating a project on c# for Windows 10. Thanks in advance.

You must use the service of Azure Notification Hub.

Push notifications to any platform and back-end

• Reach all major platforms: iOS, Android, Windows, Kindle, Baidu Use any back-end: cloud or local
• Quickly push-stream to millions of mobile devices with a single call to the API
• Customize push notifications by user, language, and location
• Dynamically define and notify user segments
• Scale to millions of mobile devices instantly

To trigger back-end notification:

var hub = NotificationHubClient
            .CreateClientFromConnectionString("Endpoint=sb://NOME_DO_SEU_APP.servicebus.windows.net/;SharedAccessKeyName=DefaultFullSharedAccessSignature;SharedAccessKey=CHAVE_DO_SEU_APP",
            "NOME_DO_SEU_APP");

var toast = @"<toast><visual><binding template=""ToastText01""><text id=""1"">Bem vindos ao VSSummit 2015</text></binding></visual></toast>";

var toastWithImage = @"<toast><visual><binding template=""ToastImageAndText01""><image id=""1"" src=""https://cdn1.iconfinder.com/data/icons/metro-ui-icon-set/512/Visual_Studio_2012.png"" /><text id=""1"">Bem vindos ao VSSummit15!</text></binding></visual></toast>";

hub.SendWindowsNativeNotificationAsync(toast).Wait();

There are other models/templates simple message, with or without image, with or without title, with counters, etc. See more models of Toast Notifications.

And to make your app receive notifications:

private async void InitNotificationHubAsync()
{
    var channel = await PushNotificationChannelManager.CreatePushNotificationChannelForApplicationAsync();

    var hub = new NotificationHub("NOME_DO_SEU_APP", "Endpoint=sb://NOME_DO_SEU_APP.servicebus.windows.net/;SharedAccessKeyName=DefaultListenSharedAccessSignature;SharedAccessKey=CHAVE_COMPARTILHADA_DO_SEU_APP");

    await hub.RegisterNativeAsync(channel.Uri);
}

In the my Github repository has an example of how to consume the service:
