Simplest REST service not working

Can anybody tell me why is this REST service not working?

namespace WCFRestExample
{
    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "Service1" in code, svc and config file together.
    public class HelloWorld : IHelloWorld
    {
        [WebGet(UriTemplate="/", ResponseFormat=WebMessageFormat.Xml)]
        public string GetData()
        {
            return "HIIII";
        }
    }
}

namespace WCFRestExample
{
    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IService1" in both code and config file together.
    [ServiceContract]
    public interface IHelloWorld
    {
        [OperationContract]
        string GetData();
    }
}

This is my web.config:

<?xml version="1.0"?>
<configuration>
  <system.web>
    <compilation debug="true" targetFramework="4.0" />
  </system.web>
  <system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior>
          <serviceMetadata httpGetEnabled="true"/>
          <serviceDebug includeExceptionDetailInFaults="true"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
  </system.serviceModel>
 <system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/>
  </system.webServer>
</configuration>

I am able to browse the service .svc and I get the page correctly but when I browse:

http://localhost:60503/HelloWorld.svc/GetData

I get a 404 page. Can anybody tell me what is happening and where can I find tutorials for WCF REST? This is the simplest service one could create and even that is not working for me.

Thanks in advance:)

It could be one reason that you did not set ServiceHostFactory properly

<%@ ServiceHost Language="C#"       
                Service="WCFRestExample.HelloWorld"  
                CodeBehind="HelloWorld.svc.cs"    
                Factory="System.ServiceModel.Activation.WebServiceHostFactory"
%>

You're not defining anywhere that this should be a REST service - neither do you have an endpoint in your web.config that uses the webHttpBinding, nor did you specify in your *.svc file to use the WebServiceHostFactory.

The simplest fix would be to fix the svc file to:

<%@ ServiceHost Language="C#" Debug="true" 
      Service="WCFRestExample.HelloWorld" CodeBehind="HelloWorld.svc.cs"
       Factory="System.ServiceModel.Activation.WebServiceHostFactory" %>

With this, your svc file now defines it wants to use the WebServiceHost (the host that understand REST) to host your service...

try http://localhost:60503/HelloWorld, and show us your Global.asax

Try changing your URI template to:

[WebGet(UriTemplate="/GetData", ResponseFormat=WebMessageFormat.Xml)]

Update

The bit in the uri template can be anything, so it can be:

/GetMySuperComplicatedData

and still be mapped to GetData()
