You need to use generic classes as a return type and made that classes serializable and then use Object datasource in front end . I am sure about that it works.

Like: Bizz layer as W.C.F service

 public List GetEmployees()
        {

            try
            {

                List emp = new List();
                emp.Add(new Employee { Code = 1, DepartMentCode = 2, FatherName = "FatherName", ManagerCode = 2,  Name = "Bilal",ManagerName="mnagername", PhoneNumber = "24421" });
            return emp;
        }

        catch (TimeoutException te)
        {
            throw te;
        }
        catch (FaultException fe)
        {
            throw new FaultException();
        }
        catch (CommunicationException ce)
        {
            throw new CommunicationException();
        }
        catch (Exception ex)
        {
            throw ex;
        }
        finally
        {
            if (client != null)
            {
                client.Close();
            }
        }
    }

//entity class

 [Serializable()]
  [DataContract()]
  public class Employee
  {
    [DataMember]
    public int Code { get; set; }
    [DataMember]
    public string Name { get; set; }
    [DataMember]
    public string FatherName { get; set; }
    [DataMember]
    public string PhoneNumber { get; set; }
    [DataMember]
    public int DepartMentCode { get; set; }
    [DataMember]
    public int ManagerCode { get; set; }
    [DataMember]
    public string ManagerName { get; set; }
}

//this is page level code . i hope you willunderstand that.
