Why does the proxy generated code create the wrong class namespace when a MessageContract is in my W

I have created two WCF Services (Shipping & PDFGenerator). They both, along with my ClientApp, share an assembly named Kyle.Common.Contracts. Within this assembly, I have three classes:

namespace Kyle.Common.Contracts
{
    [MessageContract]
    public class PDFResponse
    {
        [MessageHeader]
        public string fileName { get; set; }
        [MessageBodyMember]
        public System.IO.Stream fileStream { get; set; }
    }

    [MessageContract]
    public class PDFRequest
    {
        [MessageHeader]
        public Enums.PDFDocumentNameEnum docType { get; set; }
        [MessageHeader]
        public int? pk { get; set; }
        [MessageHeader]
        public string[] emailAddress { get; set; }
        [MessageBodyMember]
        public Kyle.Common.Contracts.TrackItResult[] trackItResults { get; set; }
    }

    [DataContract(Name = "TrackResult", Namespace = "http://kyle")]
    public class TrackResult
    {
        [DataMember]
        public int SeqNum { get; set; }
        [DataMember]
        public int ShipmentID { get; set; }
        [DataMember]
        public string StoreNum { get; set; }
    }
}

My PDFGenerator ServiceContract looks like:

namespace Kyle.WCF.PDFDocs
{
    [ServiceContract(Namespace="http://kyle")]
    public interface IPDFDocsService
    {
        [OperationContract]
        PDFResponse GeneratePDF(PDFRequest request);

        [OperationContract]
        void GeneratePDFAsync(Kyle.Common.Contracts.Enums.PDFDocumentNameEnum docType, int? pk, string[] emailAddress);

        [OperationContract]
        Kyle.Common.Contracts.TrackResult[] Test();
    }
}

If I comment out the GeneratePDF stub, the proxy generated by VS2010 realizes that Test returns an array of Kyle.Common.Contracts.TrackResult. However, if I leave GeneratePDF there, the proxy refuses to use Kyle.Common.Contracts.TrackResult, and instead creates a new class, ClientApp.PDFDocServices.TrackResult, and uses that as the return type of Test.

Is there a way to force the proxy generator to use Kyle.Common.Contracts.TrackResult whenever I use a MessageContract? Perhaps there's a better method for using a Stream and File Name as return types?

I just don't want to have to create a Copy method to copy from ClientApp.PDFDocServices.TrackResult to Kyle.Common.Contracts.TrackResult, since they should be the exact same class.

Thanks in advance, Kyle
