Please help me set up my WCF for .Net.

[foozball3000]

For starters, I should state that I'm fairly clueless on this topic.

I have a website that references a web service, using basicHttpBinding.

If I have methods that return XML as string, everything works fine, but as soon as I try to add my own custom object to use for data transfer, nothing works. I have checked the code against the MSDN library, and it seems correct.

Is there something I'm missing here?

    [ServiceContract]
    public interface IUploadService
    {
        [OperationContract]
        string ReturnNewOrder(string OrderKey);

        [OperationContract]
        Document GetAnOrder();
    }

        [DataContract]
        public class Document
        {
            private string _doccode;

            [DataMember]
            public string Doccode
            {
                get { return _doccode; }
                set { _doccode = value; }
            }

            private List<DocumentLine> _lines;

            [DataMember]
            public List<DocumentLine> Lines
            {
                get { return _lines; }
                set { _lines = value; }
            }
        }

        [DataContract]
        public class DocumentLine
        {
            private string _itemcode;

            [DataMember]
            public string ItemCode
            {
                get { return _itemcode; }
                set { _itemcode = value; }
            }

            private int _quantity;

            [DataMember]
            public int Quantity
            {
                get { return _quantity; }
                set { _quantity = value; }
            }
        }

The error only appears when I compile the website's code:

Error	14	Reference.svcmap: Failed to generate code for the service reference 'UploadService'.

When you add the Service Reference, open the Advanced dialog and uncheck the 'Re-use types in referenced assemblies' checkbox.
