This example shows the code-behind page for a Northwind-based data service, with access granted to selected entity sets.

using System.Data.Services;
using System.Linq;
using System.ServiceModel.Web;

namespace NorthwindService
    public class Northwind : DataService<NorthwindEntities>
        // This method is called only once to initialize service-wide policies. 
        public static void InitializeService(DataServiceConfiguration config)
            // Grant only the rights needed to support the client application.
           config.SetEntitySetAccessRule("Orders", EntitySetRights.AllRead 
                | EntitySetRights.WriteMerge 
                | EntitySetRights.WriteReplace );
            config.SetEntitySetAccessRule("Order_Details", EntitySetRights.AllRead
