and http://localhost:14502/MyRestService.svc/Welcome. But when i was consuming the service in the asp.net application by using jquery. It gives null result. Please give resolve that.

C#

[ServiceContract]
   public interface IMyRestService
   {
       [OperationContract]
       [WebGet( RequestFormat=WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, UriTemplate = "/Welcome",BodyStyle=WebMessageBodyStyle.Wrapped)]
       string Welcome();
       [OperationContract]
       [WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Json, UriTemplate = "Hello/{name}",BodyStyle=WebMessageBodyStyle.Wrapped)]
       string Hello(string name);

       [OperationContract]
       [WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped, UriTemplate = "Test?id={id}")]
       int Test(int id);

   }
 public class MyRestService : IMyRestService
   {

       public string Hello(string name)
       {
           return "Hello " + name;
       }

       public int Test(int id)
       {
           return id + 1;
       }

       public string Welcome()
       {
           return "Welcome to Rest Services";
       }
   }
