Writing data to sql via WCF/LINQ, null exception?

Question

Hi,

Probably something simple but i am trying to add data to sql from a silver light application by passing it a list of data(of type of a table). But when i try and pass the data across to the dataservice it is null when it is recieved?

if it helps the methods i am using are:

[OperationContract]
        public EmployeeShiftPlan AddShift(List<EmployeeShiftPlan> lsShifts)
        {
            using (tapLinqDataContext db = new tapLinqDataContext())
            {
                foreach (EmployeeShiftPlan x in lsShifts)
                {
                    db.EmployeeShiftPlans.InsertOnSubmit(x);
                    db.SubmitChanges();
                }

            }
            return lsShifts[0];
            
        }

private void btnSaveClose_Click(object sender, RoutedEventArgs e)
        {
            DataServiceClient svc = new DataServiceClient();
            svc.AddShiftCompleted += new EventHandler<AddShiftCompletedEventArgs>(svc_AddShiftCompleted);
            svc.AddShiftAsync(lsNewShifts);
        }
