title: Get folder from FolderPicker in windows phone 8.1
body: <p>I have tried this code to get a folder on Windows Phone.</p>
  
  <pre><code>    FolderPicker folderPicker = new FolderPicker();
      folderPicker.SuggestedStartLocation = PickerLocationId.Downloads;
      StorageFolder folder = await folderPicker.PickSingleFolderAsync();
  
      if (folder != null)
      {
          string Token = Windows.Storage.AccessCache.StorageApplicationPermissions.MostRecentlyUsedList.Add(folder, folder.Name);
  
      }
  </code></pre>
  
  <p>But <code>PickSingleFolderAsync</code> is not supported in Windows Phone 8.1 and <code>PickFolderAndContinue</code> is a void function.</p>
  
  <p>How can I add a folder to <code>StorageApplicationPermissions.MostRecentlyUsedList</code> ?</p>
