如何为应用程序磁贴设置初始值

Question

I would like my application tile to have the flip animation, and I have attempted to set these values in the codebehind of my MainPage, but for some reason the Application Tile does not perform the flip animation. I believe I set the back side values properly. What I have is as follows:

MainPage.xaml.cs

public void CreateApplicationTile()
    {
        var appTile = ShellTile.ActiveTiles.First();

        if (appTile != null)
        {
            var standardTile = new StandardTileData
            {
                Title = "ShareSky",
                BackgroundImage = new Uri("/Background.png", UriKind.Relative),
                BackTitle = "ShareSky",
                BackBackgroundImage = new Uri("/Background.png", UriKind.Relative),
                //BackContent = "click me!"                    
                BackContent = AppResource.Main_MainPage_ApplicationTile_BackContent
            };

            appTile.Update(standardTile);
        }
    }

As I understand, this method does not need to be associated with any events of any type (such as a click) to make it work. I am unsure of what I am doing wrong here? If I have to edit the WMAppManifest file, how would I correctly do this to incorporate the backside of the tile information?

Silly question but are you actually calling "CreateApplicationTile" in your constructor? If you didn't it would never activate.

    public MainPage()
    {
        InitializeComponent();
        CreateApplicationTile();
    }

I ran the following and got the nice happy rollovers.

   var appTile = ShellTile.ActiveTiles.FirstOrDefault(x => x.NavigationUri.ToString() == "/");
   if (appTile != null)
   {
        var standardTile = new StandardTileData
        {
                Title = "ShareSky",
                BackgroundImage = new Uri("/Background.png", UriKind.RelativeOrAbsolute),
                BackTitle = "ShareSky",
                BackBackgroundImage = new Uri("/flipped.png", UriKind.RelativeOrAbsolute),
                BackContent = "backcontent load"
        };

        appTile.Update(standardTile);
     }
