Update tiles from background agent?

Apr 9, 2013 at 4:59 PM
Hi,

I just created some tile using this Tile Toolkit:
var tile = new LiveTiles.LiveTileCurrency();
var customTile = CustomTileFactory.GetTemplatedTile("MyTile", tile, Ree7.TileToolkit.TileSize.Standard);
ShellTile.Create(new Uri(string.Format("/MainPage.xaml?0=0", "my", UriKind.Relative), customTile.GetShellTileData());
But... How do I perform an update of this tile from the back agent???

Any reply will gonna be welcome! Thanks!
