I'm not sure if I am doing something wrong or not but I am using the LiveTileHelper and I've noticed that every time I have dumped my Isolated Storage from my device to my PC that the ShellContent folder has more and more images in it. It looks to me like these images are not being cleaned up properly which means my app is continually eating more and more disk space on my device which I would like to avoid. Is this a bug or am I doing something incorrectly? The following isn't my exact code because of complexity but I am not doing anything other than this to update my tiles. My understanding is that the LiveTileHelper should be cleaning up it's own resources which doesn't appear to be happening based on my Isolated Storage.
ITileData tileData =
new
RadFlipTileData
{
BackgroundImage =
new
Uri(
"/Assets/Icons/Tiles/AccountMediumFlipTile.png"
, UriKind.Relative),
SmallBackgroundImage =
new
Uri(
"/Assets/Icons/Tiles/AccountSmallFlipTile.png"
, UriKind.Relative),
WideBackgroundImage =
new
Uri(
"/Assets/Icons/Tiles/AccountWideFlipTile.png"
, UriKind.Relative),
BackTitle = account.Name,
Title = account.Name,
BackVisualElement = TileDataHelper.MediumTileContent,
WideBackVisualElement = TileDataHelper.WideTileContent,
IsTransparencySupported =
true
};
LiveTileHelper.UpdateTile(tile, tileData);
