Question

Starting off with the example here, I created an app to pin multiple tiles to the Start screen. When I pin the first tile, I have no issues. However, when I return to the app (via the app list or the back key), and click on a second image to pin the second tile, I get an InvalidOperationException.

Here is my simple code:

    private void Pin_Tile1(object sender, RoutedEventArgs e)
    {
        StandardTileData data1 = new StandardTileData
        {
            BackgroundImage = new Uri("Assets/tile1.png", UriKind.Relative),
            Title = "Tile 1",
            BackContent = "asdf"
        };

        ShellTile.Create(new Uri("/MainPage.xaml", UriKind.Relative), data1);
    }

    private void Pin_Tile2(object sender, RoutedEventArgs e)
    {
        StandardTileData data20 = new StandardTileData
        {
            BackgroundImage = new Uri("Assets/tile2.png", UriKind.Relative),
            Title = "Tile 2",
            BackContent = "fdsa"
        };
        ShellTile.Create(new Uri("/MainPage.xaml", UriKind.Relative), data2); 

    }

Can anyone tell me what is going on? Thanks for looking

From here, each live tile must point to a unique Uri, that is where I messed up.

Full list of requirements is:

• Each Live Tile must point to a unique URI location.
• Each time that you create a secondary tile, the user will be taken to
  their home screen to view it. You can’t create more than one
  secondary tile at a time.
• Limit the number of secondary live tiles allowed.
