WCF Rest Webservice with stream

I read the following post with interest as it is an exact replica of the problem I am experiencing (and driving me insane) "For request in operation UploadFile to be a stream the operation must have a single parameter whose type is Stream." -http://social.msdn.microsoft.com/Forums/en/wcf/thread/80cd26eb-b7a6-4db6-9e6e-ba65b3095267

I have pretty much followed all code/examples I have found and yet still cannot get around this error - http://blogs.msdn.com/b/carlosfigueira/archive/2008/04/17/wcf-raw-programming-model-receiving-arbitrary-data.aspx

All I would like to achieve is to post an image(jpeg/png) from an android device using the standard filename/stream parameters.More than likely it is something simple that I have misconfigured, misunderstood or left out but I need to have a solution for proof of concept.

 public interface IConXServer
    {
    [OperationContract]
    [WebInvoke(UriTemplate = "UploadImage({fileName})", Method="POST")]
    void UploadImage(string fileName, Stream imageStream);
    }

 public class ConXWCFServer : IConXServer
    {
    public void UploadImage(string fileName, Stream imageStream)
       {
       //implement image save
       }
    }

       <standardEndpoint name="webHttpEndpoint" helpEnabled="false"/>

Using vs2010 and IIS Express. If I comment out the above method all the others methods work and return data as well as the wsdl query

Regards and thanks in advance Kern

You mention WSDL, which leads me to believe you're getting the error while trying to browse the metadata endpoint for the service. So, first off, WSDL and REST don't go together, so you shouldn't expect to use it at all for a REST interface. Forget the service metadata concept even exists in the REST world.

Next While it's true the REST's webHttpBinding supports parameters in front of the Stream body parameter, other bindings do not and there must either be a single Stream parameter or a message contract with headers and a stream body.

So, in the end, the problem is not with the REST webHttpBinding at all, I bet it works just fine. If it doesn't I would be absolutely shocked because you're not doing anything that shouldn't work in that department. The problem is that you're expecting the metadata endpoint to generate WSDL for the service contract you've defined and that's just not supported.
