If you don't have the namespaces the same for the two parts of the partial class it can fail also.
Have a look in the generated file (Show all files and look for the .g.cs file) and see if the Title class exists in there. T.

However we created a partial class in the same project containing the EDMX and applied the [include] attr like so:- [MetadataType(typeof(PersonMetadata))] public partial class Person { internal static class PersonMetadata { [Include] public static Title Title { get; set; } } } And this is the method inside the domain service:- public IQueryable<Person> GetPeople() { return this.ObjectContext.People.Include("Title"); } And here is the generated data contract on the client:- public sealed partial class Person : Entity { /// <summary> /// Gets or sets the associated <see cref="Title"/> entity. /// </summary> [Association("Title_Person", "TitleId", "Id", IsForeignKey=true)] [XmlIgnore()] public Title Title { get { if ((this._title == null)) { this._title = new EntityRef<Title>(this, "Title", this.FilterTitle); } return this._title.Entity; // ***** throws exception here } set { . } } .. } Exception Details:- {System.InvalidOperationException: This EntityContainer does not contain an EntitySet of type 'Deintegro.DAL.Data.Title'. If the type is external to this EntityContainer, please make sure you've called AddReference to establish the external link. at System.ServiceModel.DomainServices.Client.EntityContainer.GetEntitySet(Type entityType) at System.ServiceModel.DomainServices.Client.EntityRef`1.get_Entity() at Deintegro.DAL.Data.Person.get_Title()} System.Exception {System.InvalidOperationException} On Thu, Aug 12, 2010 at 8:57 PM, Shingi Mutandwa <shingi.mutan...@gmail.com> wrote: Deleted the generated_code folder but I am still having the same issue. The domain service class was generated by Visual studio and I did not add anything to it.

For example, have you got any [Insert], [Update], [Delete], [Query] methods within the domain service?
