Question

I’m developing metro app using Windows 8 release preview and C#(VS 2012),I’m using below code to update Application tile.

TileUpdateManager.CreateTileUpdaterForApplication().EnableNotificationQueue(true);

XmlDocument TileXML = TileUpdateManager.GetTemplateContent(TileTemplateType.TileWideImage);                

XmlNodeList imageAttribute = TileXML.GetElementsByTagName("image");
((XmlElement)imageAttribute[0]).SetAttribute("src", "ms-appx:///Assets/Tile.png");
((XmlElement)imageAttribute[0]).SetAttribute("alt", "red graphic");

TileNotification notify = new TileNotification(TileXML);
notify.ExpirationTime = DateTimeOffset.UtcNow.AddSeconds(10);

TileUpdateManager.CreateTileUpdaterForApplication().Update(notify);

But my Application Tile is not updating, I don’t know what I’m missing and where I’m doing wrong, please help me.

I got the answer, its about adding Extension file “NotificationExtensions.winmd” as my reference and also i have couple of questions

1. When i run above code by setting my target device as “Local
   Machine” it works but when i set it to “Simulator” it doesn’t, Can
   any one explains me please why.

2. We have expiration time for tiles by using below line
   notify.ExpirationTime = DateTimeOffset.UtcNow.AddSeconds(10);
   what i have to do if want the live tile to be running continuously,

   Please let me know if have any links or study material
   Thanks in advance.
