New Live tiles don't work in Windows Phone Silverlight 8.1 apps?

Question

So when I was watching this video from BUILD I thought it's gonna be easy...

But I can't seem to get the tile of my WP Silverlight 8.1 app to change by doing the following.

    const string xml = "<tile>"
           + "<visual>"
           + "<binding template='TileSquareText01'>"
           + "<text id='1'>testing 123</text>"
           + "</binding>  "
           + "</visual>"
           + "</tile>";

    var xmlDoc = new XmlDocument();
    xmlDoc.LoadXml(xml);

    var tileNotification = new TileNotification(xmlDoc);
    TileUpdateManager.CreateTileUpdaterForApplication().Update(tileNotification);

Please note I've also created a Windows RunTime Windows Phone 8.1 with exactly the same code and it works just fine.

On msdn, it clearly states that TileUpdateManager supports Windows Phone Silverlight 8.1. So I don't really know what's missing here.

In your manifest, make sure the notification type is set to WNS. If you set it to MPNS, then you have to use notifications the old way.
