I'm sending a part of the sample code that i've return, The following is the one that wrote in my application. Can any check it once and let me know the best solution for the below problem.

PAGE_LOAD
 void OrganizationBaseLine_Loaded(

object sender, RoutedEventArgs e)
        {
//Here Service reference1 is my WCF Service reference So I Created an object of that class as obj
 ServiceReference1.MNetMetricsServiceClient obj = new MNetMetricSystem.ServiceReference1.MNetMetricsServiceClient();
 obj.GetAllDepartmentsCompleted += new EventHandler<MNetMetricSystem.ServiceReference1.GetAllDepartmentsCompletedEventArgs>(obj_GetAllDepartmentsCompleted);
            obj.GetAllDepartmentsAsync();

         }

 void obj_GetAllDepartmentsCompleted(object sender, MNetMetricSystem.ServiceReference1.GetAllDepartmentsCompletedEventArgs e)
        {
            cmdDepartMent.ItemsSource = e.Result;// this is a list binding that data to combobox
        }


The interface I'm using is

[ServiceContract]
    public interface IMNetMetricsService
    {
        [OperationContract]
         List<MYList> GetAllDepartments();
}
The class that's inheriting from the above Interface is
 public class MNetMetricsService : IMNetMetricsService
    {
      
        DLMetrics objMetrics = new DLMetrics();
         List<MYList> mlist = new List<MYList>();
            
        List<MYList> IMNetMetricsService.GetAllDepartments()
        {
           
            DataTable dt = objMetrics.DLGetAllDepartments(); // this is the method returns dept table(FROM Data Access Layer) so i converted it to List to bind to the combobox
         
                mlist.Add(new MYList() { MyTable=dt});
         
            return mlist;
        }

The above is the List I'm binding at the front end. i.e., in  page.xaml.cs Page load event. and I'm getting the following error.

Here I didn't use linq. Without LINQ I'm using a WCF Service. 1st of  all is it possible without LINQ to get data from database to silverlight data bindings to controls. If possible can u send me the solution.

If I used LINQ I'm getting the result. Without LINQ is it possible what is the best solution.........................
