Getting FaultException error after publishing WCF

Question

I have developed WCF service for my one of the desktop application and host into Azure server with DB.

I have just connect WCF service Url on my local Desktop application.

Once i called login method from application. then no issue.

Once i called my second method then always i got FaultException error

Error is like that see the inner exception for detail error. but once i go inside then inner exception is null.

I also put <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" /> into my wcf web.config

Once i connect local WCF with live db with my desktop app then everything is work fine.

Once i connect Live WCF with live db with my desktop app then not working insert and update data.

my second method having this code.

 public class Service1 : IService1
    {
     public void method1(int nm_Id, string f_LoginStatus)
            {
                class1 lo_class = new class1();

                    DateTime dt = DateTime.UtcNow;
                    //check records exist or not
                        lo_class.dt_date = dt;
                        lo_class.dtCreatedOn = dt;
                        lo_tblAttendance.dtUpdatedOn = dt;

                        _context.tblAttendances.Add(lo_tblAttendance);

                        Save();
                    }
           }
    }

 [ServiceContract]
    public interface IService1
    {
        [OperationContract]
        [FaultContract(typeof(InitializationFault))]
        void method1(int nm_Id, string f_LoginStatus);
     }


   [DataContract]
    public class InitializationFault
    {
        public InitializationFault(Exception exc, string msg)
        {
            Exception = exc;
            Message = msg;
        }

        [DataMember]
        public Exception Exception { get; set; }

        [DataMember]
        public string Message { get; set; }
    }

Calling above method from desktop app:

  lo_loginServices = new MyService.Service1Client();
  try
                    {
                        lo_loginServices.method1(lo_EmpId, "In"); // getting inner exception error here
                    }
                    catch (FaultException<InitializationFault> ex)
                    {
                        Console.WriteLine("FaultException<InitializationFault>: " + ex.Detail);
                        //more
                    }

I've write catch section then also i can't able to see actual error.

You may try to Include Exception Details in Fault. Setting IncludeExceptionDetailInFaults to true to enables exception information to flow to clients for debugging purposes.
