title: C# SSRS 'ReportExecutionService' does not contain a definition for 'ListChildren'
body: <p>I'm trying to get a list of folders and RDL files in those folders on an SSRS 2008 server and I'm getting the following messages when trying to iterate through the folders. </p>
  
  <p>'ReportExecutionService' does not contain a definition for 'ListChildren' and no accessible extension method 'ListChildren' accepting a first argument of type 'ReportExecutionService' could be found (are you missing a using directive or an assembly reference?)</p>
  
  <pre><code>        var rs05 = new SSRS2005.ReportExecutionService();
          rs05.Url = "http://&lt;servername&gt;/ReportServer/ReportService2005.asmx?wsdl";
          rs05.Credentials = System.Net.CredentialCache.DefaultCredentials;
          var reports = rs05.ListChildren("/");
  </code></pre>
  
  <p>I have it exactly as every example out there. Is ListChildren not exposed? Am I missing something?</p>
