将项目从WP7升级到WP8后，动态磁贴无效

Question

将项目从WP7升级到WP8后，动态磁贴无效。有谁知道原因？ 我已经完成了自定义磁贴，我将其保存为IsolatedStorage中的图片。 计划代理中的Tile代码：

ShellTile tile = ShellTile.ActiveTiles.FirstOrDefault();
                   if (tile != null)
                   {
                       FlipTileData data = new FlipTileData()
                       {
                           SmallBackgroundImage = new Uri("isostore:" + mediumTile, UriKind.RelativeOrAbsolute),
                           BackgroundImage = new Uri("isostore:" + mediumTile, UriKind.RelativeOrAbsolute),
                           WideBackgroundImage = new Uri("isostore:" + wideTile, UriKind.RelativeOrAbsolute)
                       };

                   tile.Update(data);
               }
NotifyComplete();

要在IsolatedStorage中使用图像，您需要使用/ Shared / ShellContent路径。以下是修复代码：

ShellTile tile = ShellTile.ActiveTiles.FirstOrDefault();
                   if (tile != null)
                   {
                       FlipTileData data = new FlipTileData()
                       {
                           SmallBackgroundImage = new Uri("isostore:/Shared/ShellContent/" + mediumTile, UriKind.RelativeOrAbsolute),
                           BackgroundImage = new Uri("isostore:/Shared/ShellContent/" + mediumTile, UriKind.RelativeOrAbsolute),
                           WideBackgroundImage = new Uri("isostore:/Shared/ShellContent/" + wideTile, UriKind.RelativeOrAbsolute)
                       };

                   tile.Update(data);
               }
NotifyComplete();
