簡単なWCFデモを作成しました：サーバー側：

namespace ServerSide
{
    class Program
    {
        static void Main(string[] args)
        {
            System.ServiceModel.ServiceHost host = 
                new System.ServiceModel.ServiceHost(typeof(HelloIndigo.HelloIndigoService), new Uri("http://locahost:8000/HelloIndigo"));
            host.AddServiceEndpoint(typeof(HelloIndigo.IHelloIndigoService), new System.ServiceModel.BasicHttpBinding(), "HelloIndigoService");
            host.Open();

            Console.Write("Terminate Server");
            Console.ReadLine();
        }
    }
}

クライアント側：

    namespace ClientSide
    {
        class Program
        {
            static void Main(string[] args)
            {
                System.ServiceModel.EndpointAddress ep =
                    new System.ServiceModel.EndpointAddress("http://locahost:8000/HelloIndigo/HelloIndigoService");
                IHelloIndigoService proxy = 
                    System.ServiceModel.ChannelFactory<IHelloIndigoService>.CreateChannel(new System.ServiceModel.BasicHttpBinding(), ep);
                string s = proxy.HelloIndigo();
                Console.WriteLine(s);
                Console.ReadLine();
            }
        }
     }

次に、ServerSideを実行します。CLientSideを実行しようとすると、次のエラーメッセージが表示されます。http：// locahost：8000 / HelloIndigo/HelloIndigoService へのHTTP応答の受信中にエラーが発生しました。これは、HTTPプロトコルを使用していないサービスエンドポイントバインディングが原因である可能性があります。これは、サーバーによってHTTP要求コンテキストが中止されたことが原因である可能性もあります（おそらくサービスのシャットダウンが原因です）。詳細については、サーバーログを参照してください。

そしてエラーの詳細：

    System.ServiceModel.CommunicationException was unhandled
      Message="An error occurred while receiving the HTTP response to http://locahost:8000/HelloIndigo/HelloIndigoService. This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down). See server logs for more details."

あなたのマシンは呼ばれていますlocahostか?? 通常、これらのマシンはローカル ホストと呼ばれます。そのため、サービス用に次の URL を試してください (サーバー側とクライアント側の両方で):

new Uri("http://localhost:8000/HelloIndigo")

この変更により、問題なくサンプルを再作成することができました。
