body: <p>Image of project structure:
  <a href="http://i.imgur.com/yHdZxA2.png" rel="nofollow">http://i.imgur.com/yHdZxA2.png</a></p>
  
  <p>I'm quite sure that it is my link that doesn't work.
  I've tried:</p>
  
  <pre><code>"ms-appx:/TileImages/{0}/{1}/{2}", "ms-appx:///TileImages/{0}/{1}/{2}", "ms-appx:///Local/TileImages/{0}/{1}/{2}", "ms-appdata:///Local/TileImages/{0}/{1}/{2}", 
  </code></pre>
  
  <p>but nothing seems to work.</p>
  
  <p>But when I try another link "<a href="http://tiles.kartat.kapsi.fi/peruskartta/" rel="nofollow">http://tiles.kartat.kapsi.fi/peruskartta/</a>{0}/{1}/{2}" it works.
  　</p>
  
  <pre><code>namespace BingMapsWindowsStoreApp
  {
  
  public sealed partial class MainPage: Page
  {
  private string MyLink = "ms-appx:/TileImages/{0}/{1}/{2}.png";
  public MainPage()
  {
  
  this.InitializeComponent();
  }
  protected async override void OnNavigatedTo(NavigationEventArgs e)
  {
  MapTileLayer layer = new MapTileLayer();
  layer.GetTileUri += layer_GetTileUri;
  this.myMap.TileLayers.Add(layer);
  }
  private async void layer_GetTileUri(object sender, GetTileUriEventArgs e)
  {
  e.Uri = this.CreateTileUri(e);
  }
  private Uri CreateTileUri(GetTileUriEventArgs e)
  {
  return new Uri(string.Format(MyLink, e.LevelOfDetail, e.X, e.Y));
  }
  }
  }
  </code></pre>
