WCF REST 404 when trying GET

Question

I keep getting a 404 on a very basic WCF service that I want to expose via REST - I'm trying to access it by going to this URL when debugging: http://localhost:62888/Service1.svc/xml/data/test

I can view the service info at http://localhost:62888/Service1.svc but not at http://localhost:62888/Service1.svc/xml

I'm using .Net 4 and its a WCF Service Application project. I tried debugging with Cassini as well as IIS Express

Web.Config

<?xml version="1.0"?>
<configuration>

  <system.web>
    <compilation debug="true" targetFramework="4.0" />
  </system.web>
  <system.serviceModel>
    <services>
      <service name="Service1">
        <!-- address is relative-->
        <endpoint address="xml" binding="webHttpBinding" behaviorConfiguration="webHttp" contract="IService1" />
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
      </service>
    </services>

    <behaviors>
      <serviceBehaviors>
        <behavior>
          <serviceMetadata httpGetEnabled="true"/>
          <serviceDebug includeExceptionDetailInFaults="false"/>
        </behavior>
      </serviceBehaviors>
      <endpointBehaviors>
        <behavior name="webHttp">
          <webHttp />         <!-- enables RESTful in conjunction with webHttpBinging -->
          <enableWebScript /> <!-- allows ajax communication -->
        </behavior>
      </endpointBehaviors>
    </behaviors>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
  </system.serviceModel>
 <system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/>
  </system.webServer>

</configuration>

IService.cs

using System.ServiceModel;
using System.ServiceModel.Web;

namespace CI.WcfRestTest
{
    public interface IService1
    {
        [OperationContract]
        [WebGet(UriTemplate = "/data/{id}")]
        string GetData(string id);
    }
}

Service1.svc.cs

namespace CI.WcfRestTest
{
    public class Service1 : IService1
    {
        public string GetData(string id)
        {
            return string.Format("You entered: {0}", id);
        }
    }
}

I've read a bunch of articles on the subject including this one REST / SOAP endpoints for a WCF service . Perhaps there's something in Cassini or my machine config thats goofing things up? I've read of issues with Windows Vista, but I'm on Windows 7 Pro. Perhaps it has something to do with a WCF Service Application as opposed to a WCF Service Library?

It might be as simple as having the wrong service name in your config.

Currently, you have:

<services>
  <service name="Service1">

BUT: this needs to be the fully qualified service name - including any namespaces!

So try this instead:

 <services>
    <service name="CI.WcfRestTest.Service1">
       <!-- address is relative-->
       <endpoint address="xml" 
                 binding="webHttpBinding" behaviorConfiguration="webHttp" 
                 contract="CI.WcfRestTest.IService1" />
      <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
    </service>
</services>

Just replace Service1 with CI.WcfRestTest.Service1 (and the same for the contract). Does that solve you problem??

Thanks! That worked (facepalm), I also had to remove the since that doesn't work with UriTemplate — Chris Klepeis, Dec 23 '11 at 19:21
