title: Method from WCF service not showing up in client app
body: <p>My latest venture in C# coding is learning about WCF services. I'm attempting to make a very simple service. It has one method that isn't default and it simply returns a string of a user inputted integer multiplied by two. I've uploaded the service to aspspider.com, and have created a winforms client app. However when looking through the service class it only shows the GetData method. I'm honestly puzzled by this, and can't understand for the life of me why my method won't show up. I've used the svcutil.exe command from the command line and still nothing. If someone could help me out I'd really appreciate it! Here's my code:</p>
  
  <p>Service Code:</p>
  
  <pre><code>using System;
  using System.Collections.Generic;
  using System.Linq;
  using System.Runtime.Serialization;
  using System.ServiceModel;
  using System.ServiceModel.Web;
  using System.Text;
  using System.Web.Services;
  
  namespace WcfService1
  {
      public class Service1 : IService1
      {        
          public string GetData(int value)
          {
              return string.Format("You entered: {0}", value);
          }
  
          public string GetDouble(int value) //Method that isn't showing up
          {
              return (value * 2).ToString();
          }
       }
    }
  </code></pre>
  
  <p>Service Interface:</p>
  
  <pre><code>using System;
  using System.Collections.Generic;
  using System.Linq;
  using System.Runtime.Serialization;
  using System.ServiceModel;
  using System.ServiceModel.Web;
  using System.Text;
  
  namespace WcfService1
  {
      [ServiceContract]
      public interface IService1
      {
          [OperationContract]
          string GetData(int value);
  
          [OperationContract]
          public string GetDouble(int value); //Method that isn't showing up
  
          // TODO: Add your service operations here
      }   
  }
