I am creating my first rest api. I followed below link. http://www.codeproject.com/Articles/105273/Create-RESTful-WCF-Service-API-Step-By-Step-Guide.Link is excellent.
Steps 1: I have created new project WCFservice application.Deleted already created Interface and class.Added new service into it.Project name is 'RestService' and service name is 'IRestServiceImpl'Working well when accessing through browser.But when I try to consume it through client/web application ,I am getting error.I unable to see any endpoint in client's webconfig file.When I am adding service reference ,it is showing 2 reference found.How 2?So again I deleted and entered new service reference ,that time I unchecked reused type in referenced asseblies" but no success.What to do now? Step 4 : written here because in below box unable to fit all code of step 4

What I have tried:

step 2: Interface

namespace RestService
{
    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IRestServiceImpl" in both code and config file together.
    [ServiceContract]
    public interface IRestServiceImpl
    {
        [OperationContract]
        [WebInvoke(Method="GET",ResponseFormat=WebMessageFormat.Xml,BodyStyle=WebMessageBodyStyle.Wrapped,UriTemplate="xml/{id}") ]
        string XmlData(string id);

        [OperationContract]
        [WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped, UriTemplate = "json/{id}")]
        string JSONData(string id);
    }
}
step 3: Class Implementing Interface
namespace RestService
{
    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "RestServiceImpl" in code, svc and config file together.
    // NOTE: In order to launch WCF Test Client for testing this service, please select RestServiceImpl.svc or RestServiceImpl.svc.cs at the Solution Explorer and start debugging.
    public class RestServiceImpl : IRestServiceImpl
    {
      public  string XmlData(string id)
        {
            return "Your id is " + id;
        }

      public string JSONData(string id)
      { 
          return "Your id is " + id;
      }
    }
}
Step 4 : Webconfig
