WCF REST communication with Windows Phone - wcf

Question

I'm having some trouble regarding a rest request sent from my Windows Phone app via RestSharp to a self hosted WCF service I have made. The request works fine in the emulator and the request returns a result but when I try to perform the request on my app on an actual device it fails and the request does not return anything.
Having done a fair amount of research I have discovered that apparently webHttpBinding is not supported on Windows Phone and therefore I need to add a basicHttpBinding endpoint to my Web.config file. However, when I try to do this I get several errors associated with having more than one endpoint and I can't seem to get any solution to successfully work with both of these. Switching the endpoint to basicHttpBinding and commenting out webHttpBinding also causes an error when I navigate to localhost:81/mywebservice.svc
"System.InvalidOperationException: For request in operation analyseFace to be a stream the operation must have a single parameter whose type is Stream."
asking for the stream that should be attached with a request. It shows a normal help page using the original code and the same address.
My web.config file

My WCF SERVICE
[ServiceContract]
public interface Ivizage
{
[WebInvoke(UriTemplate = "/agerecog/{auth}", Method = "POST")]
VizageResult analyseFace(string auth, Stream dataStream);
}
I'm wondering if someone can help me work out what code I have to edit in my web.config to make this work for both endpoints as I haven't had any luck so far with things I've tried

Answer 1

Your code seems to be a REST service, but basicHttpBinding supports SOAP. So please continue to use webHttpBinding. However, on the Windows Phone side, the WCF cannot be used, it is needed to use WebClient or HttpWebRequest to access a REST service. WCF can just help us to access a SOAP service.
In addition, you mentioned the application works fine in the emulator, so it is unlikely to be a coding issue. It would be better if you can check whether your real phone device is able to access internet. Please also make sure you're using the cloud service's address instead of 127.0.0.1. Local address will not work on a real device.

Answer 2

From the exception and your config - you are using simplified configuration which by default uses basicHttpBinding. You have to explicity define service end point
<services>
<service name="WcfRest.Ivizage">
<endpoint behaviorConfiguration="restbehavior" binding="webHttpBinding"
contract="WcfRest.Ivizage" />
</service>
</services>
Edit: looks like webHttp is not supported
