Using New ADO.NET Data Services Functionalities

In order to use the new functionalities (count, projections, server paging, for instance) supplied by version 1.5 of ADO.NET Data Services (see my previous post), you must explicitly enable them on the service side.

public static void InitializeService(DataServiceConfiguration config)
{
    config.EnableTypeConversion = true;
    config.DataServiceBehavior.MaxProtocolVersion = DataServiceProtocolVersion.V2;
    config.UseVerboseErrors = true;
    config.SetEntitySetAccessRule("*", EntitySetRights.All);
    config.SetServiceOperationAccessRule("*", ServiceOperationRights.All);
}

Note that you need to use the DataServiceConfiguration instead of the IDataServiceConfiguration interface, which was the one that the wizard previously declared.
