RESTful WCF Service returns "The resource cannot be found." error

19,164

Your endpoint isn't a REST endpoint, it's a "normal" SOAP endpoint (binary encoding / http transport). REST endpoints are defined with a specific binding (webHttpBinding) and behavior (webHttp). Also, Add Service Reference doesn't work for REST endpoints, which is also an indication that if it works for you, then you're not using a REST endpoint.

To change your endpoint to be RESTful, you can change the web.config as shown below (it actually adds a REST endpoint in addition to the SOAP one which you already have).

<system.serviceModel>
    <services>
        <service name="ResearchUploadService.Service1" behaviorConfiguration="ResearchUploadService.Service1Behavior">
            <!-- Service Endpoints -->

        <endpoint address="customBinding" binding="customBinding" bindingConfiguration="basicConfig" contract="ResearchUploadService.IService1"/>
        <endpoint address="" binding="webHttpBinding" behaviorConfiguration="REST" contract="ResearchUploadService.IService1"/>
        </service>
    </services>
    <behaviors>
        <serviceBehaviors>
            <behavior name="ResearchUploadService.Service1Behavior">

                <serviceMetadata httpGetEnabled="true"/>
                <serviceDebug includeExceptionDetailInFaults="true"/>
            </behavior>
        </serviceBehaviors>
        <endpointBehaviors>
           <behavior name="REST">
             <webHttp/>
           </behavior>
        </endpointBehaviors>
  </behaviors>
  <bindings>
     <customBinding>
        <binding name="basicConfig">
           <binaryMessageEncoding/>
           <httpTransport transferMode="Streamed" maxReceivedMessageSize="67108864"/>
        </binding>
     </customBinding>

  </bindings>
</system.serviceModel>

    I have a RESTful service that doesn't work. When I type the URI into the address bar, I receive this error:

    The resource cannot be found.

    Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.

    Requested URL: /VirtualRUS/Service1.svc/

    I can't tell why its not working. I compared my code and web.config to a working example, and I can't find any differences.

    EDIT: Also, I'm able to use the service just fine if I use a service reference. It just doesn't work if I navigate to the URI, or more importantly, when I try to make a WebRequest.

    Does anyone have any idea why this wouldn't work?

    Service1.cs:

    [ServiceContract]
    public interface IService1
    {
       [OperationContract]
       [WebGet(UriTemplate = "/")]
       string Test(); 
    }
    

    Service1.svc.cs:

    [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall)]
    public class Service1 : IService1
    {
       public string Test()
       {
          return "It works!!";
       }
    }
