title: Show thumbnails in ListView in Windows RT
body: <p>I have a code to get the thumbnails, that looks like this</p>
  
  <pre><code>public async Task&lt;bool&gt; SetThumbnail(Model.FileInfo Fil)
  {
     try
     {
        // Set the File
        var File = await GetStorageFile(Fil);
  
        // Set the File's thumbnail
        Fil.FileThumbnail = await File.GetThumbnailAsync(Windows.Storage.FileProperties.ThumbnailMode.ListView);
  
        // Set the File
        Fil.File = File;
  
        // Return true as it was successfully executed
        return true;
     }
     // Otherwise it was not successful so return false
     catch (Exception e) {
        return false;
     }
  }
  </code></pre>
  
  <p>The GetStorageFile-method looks like this</p>
  
  <pre><code>private async Task&lt;StorageFile&gt; GetStorageFile(Model.FileInfo FileInf)
  {
     // Create (and open the Folder)
     var Folder = await _Folder.CreateFolderAsync(_FilesFolderName, CreationCollisionOption.OpenIfExists);
  
     // Get the File
     return await Folder.GetFileAsync(FileInf.ID + "." + FileInf.Extension);
  }
  </code></pre>
  
  <p>It works great 1st time, but when I show the List the second time, the Thumbnails does not show up</p>
  
  <p>What could be wrong, when I run it the 2nd time?</p>
