Why does the proxy generated code create a new class when a MessageContract is in my WCF Service?
- by DaleyKD
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
