title: Add function to Convert function
body: <p>I am trying to use <code>Convert</code> function from <code>IValueConverter</code>, but I have to call another function in it. I will use his return value but I got that error telling me to return an object value in the converter, any idea how can I avoid this please.</p>
  
  <pre><code>public void Convert(object value, Type targetType, object parameter, CultureInfo culture)
  {
      RestClient client = new RestClient();
      client.BaseUrl = "http://";
  
      RestRequest request = new RestRequest();
      request.Method = Method.GET;
      request.AddParameter("action", "REE");
      request.AddParameter("atm_longitude", location.Longitude);
  
      client.ExecuteAsync(request, ParseFeedCallBack_ListDistance);
  }
  public void ParseFeedCallBack_ListDistance(IRestResponse response)
  {
      if (response.StatusCode == HttpStatusCode.OK)
      {
          ParseXMLFeedDistance(response.Content);
      }
  }
  private string ParseXMLFeedDistance(string feed)
  {
  .... return myvalueToBind;
  </code></pre>
