Hi,

I have a WCF service like:

[OperationContract]
[WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json, UriTemplate = "SelectQueryResult")]
string GetSelectQueryResult(ClsPagingInfo objClsPagingInfo);

And I consuming it in a MVC project like:

objClsPagingInfo.iPageSize = Convert.ToInt32(PageSize);
                   objClsPagingInfo.iCurrentPageIndex = Convert.ToInt32(CurrentPageIndex);
                   objClsPagingInfo.iPageCount = 1000;
                   objClsPagingInfo.sQuery = txtQuery.Trim();

                   DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(ClsPagingInfo));
                   MemoryStream ms = new MemoryStream();
                   ser.WriteObject(ms, objClsPagingInfo);
                   string data = Encoding.UTF8.GetString(ms.ToArray(), 0, (int)ms.Length);

                   WebClient webClientNewTicket = new WebClient();
                   webClientNewTicket.Headers["Content-type"] = "application/json";
                   webClientNewTicket.Encoding = Encoding.UTF8;
                   string sResultData = webClientNewTicket.UploadString("http://localhost:50750/TnsEspService.svc/SelectQueryResult", "POST", data);

                   sResultDataReturn = JsonConvert.DeserializeObject<string>(sResultData);
                   DataTable ResultDataTable = (DataTable)JsonConvert.DeserializeObject(sResultDataReturn, (typeof(DataTable)));

                   ViewBag.DataTableTest = ResultDataTable;

It works fine when WCF returns small data but when WCF returns a huge data then It through "Timeout error".

Please suggest some solution for this issue.

Thank you,
