WCF sevice doesn't load in published application

WCF sevice doesn't load in published application

I have problem with Silverlight-enabled WCF service, so this is my service:

    [ServiceContract(Namespace = "")]             [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]             public class WhatsNewService             {                 string connectonString = ConfigurationManager.ConnectionStrings["sqlConnectionString"].ConnectionString;                  [OperationContract]                 public List<WhatsNewDataClass> GetData()                 {                     SqlConnection sqlCon = new SqlConnection(connectonString);                     DataSet objectSet = new DataSet();                     SqlCommand sqlCom = new SqlCommand();                     sqlCom.Connection = sqlCon;                     sqlCom.CommandText = "SELECT  * FROM [dbo].[WhatsNew] WHERE [rowStatus]='Unseen' ORDER BY [changeDate] ASC ;";                     SqlDataAdapter dataAdapter = new SqlDataAdapter();                     dataAdapter.SelectCommand = sqlCom;                     dataAdapter.Fill(objectSet);                     List<WhatsNewDataClass> result = new List<WhatsNewDataClass>();                     WhatsNewDataClass dataObject;                      if (objectSet.Tables.Count > 0)                     {                         foreach (DataRow dr in objectSet.Tables[0].Rows)                         {                                dataObject = new WhatsNewDataClass();                             dataObject.changeType = dr["changeType"].ToString();                             dataObject.objectType = dr["objectType"].ToString();                             dataObject.objectName = dr["objectName"].ToString();                             dataObject.changeDescription = dr["changeDescription"].ToString();                             dataObject.changeDate = dr["changeDate"].ToString();                             dataObject.changedBy = dr["changedBy"].ToString();                             dataObject.rowStatus = dr["rowStatus"].ToString();                             dataObject.ProjectID = dr["ProjectID"].ToString();                             dataObject.UserName = dr["UserName"].ToString();                             dataObject.itemID = dr["ID"].ToString();                             dataObject.refType = dr["refType"].ToString();                             dataObject.parentID = dr["parentID"].ToString();                              result.Add(dataObject);                          }                     }                   return result;             }   } 

So I call this service in my client part, everything is working fine, but when I publish it and put in my website, service don't return values. Any suggestions?
