WCF - CODEGEN: Generating message contract since message FileRequest has headers
- by Tri Q
I am aware that there is a similar question here with no solution.
I'm working on a WCF streaming service over HTTP.
Here are my MessageContract
[MessageContract]
public class FileRequest
{
#region Message Header
[MessageHeader(MustUnderstand = true)]
public Credential Credentials { get; set; }
#endregion
#region Message body
[MessageBodyMember(Order = 1)]
public FileInfo FileInfo { get; set; }
#endregion
#region Ctor
// ...
#endregion
}
[MessageContract]
public class FileRequestResponse
{
#region Message Header
[MessageHeader(MustUnderstand = true)]
public FileInfo FileHeader { get; set; }
[MessageHeader(MustUnderstand = true)]
public OperationResult<bool> OperationResult { get; set; }
#endregion
#region Message Body
[MessageBodyMember]
public Stream FileStream { get; set; }
#endregion
#region Constructor
// ...
#endregion
}
Here is my ServiceContract
[ServiceContract(Namespace = "https://service.contract.example.com")]
public interface IUpdateService
{
[OperationContract(Action = "GetUpdates")]
OperationResult<List<FileInfo>> GetUpates(ApplicationInfo applicationInfo, Credential credential);
[OperationContract(Action = "GetFile")]
FileRequestResponse FileRequest(FileRequest fileRequest);
}
Now the question is why I am getting this error:
// CODEGEN: Generating message
contract since message FileRequest has
headers
When I add my service reference. The end result is that the service contract wraps the FileRequest operation into a wrapper which I do not want.
public FileInfo FileRequest(Credential Credentials, FileInfo, out OperationResult<bool> OperationResult, out System.IO.Stream FileStream)
NOTE:
I have not checked the "Always generate message contracts" in the service reference.
