Реализация контракта

using System;

        public double Add(double n1, double n2)

Создание службы

_создать консольное приложение(GettingStartedHost) и добавить ссылки на созданную службу и на System.ServiceModel_

using System;
using System.ServiceModel;
using System.ServiceModel.Description;
using GettingStartedLib;

namespace GettingStartedHost
{
    class Program
    {
        static void Main()
        {
            // step 1. Create a URI to serve as the base address.
            var baseAddress = new Uri("http://localhost:8000/GettingStarted");

            // step 2. Create a server host instance.
            var selfHost = new ServiceHost(typeof (CalculatorService), baseAddress);

            try
            {
                // step 3. Add a service endpoint.
                selfHost.AddServiceEndpoint(typeof (ICalculator), new WSHttpBinding(), "CalculatorService");

                // step 4. Enable metadata exchange.
                var smb = new ServiceMetadataBehavior
                    {
                        HttpGetEnabled = true
                    };
                selfHost.Description.Behaviors.Add(smb);

                // step 5. Start the service.
                selfHost.Open();
                Console.WriteLine("The service is ready");
                Console.WriteLine("Press <ENTER> to terminate service");
                Console.WriteLine();
                Console.ReadLine();

                // Close the ServiceHostBase to shutdown the service.
                selfHost.Close();
            }
            catch (CommunicationException exception)
            {
                Console.WriteLine(exception.Message);
                selfHost.Abort();
            }
        }
    }
}

Создание клиента

_Сначала нужно добавить ссылку на службу_ http://localhost:8000/GettingStarted и на System.ServiceModel

using System;
using GettingStartedClient.ServiceReference1;

namespace GettingStartedClient
{
    class Program
    {
        static void Main()
        {            
            Console.ReadLine();
        }
    }
}

Настройка клиента (задание конечной точки)

edit App.config

[makaveli713]

Использование клиента

_Открыть Program.cs в GettingStartedClient_

using System;
using GettingStartedClient.ServiceReference1;

namespace GettingStartedClient
{
    class Program
    {
        static void Main()
        {
            // step 1. Create an instance of the WCF proxy.
            var client = new CalculatorClient();

            // step 2. Call the servic operation.
            // Call the Add service operation.
            var value1 = 100.00D;
            var value2 = 15.99D;
            var result = client.Add(value1, value2);
            Console.WriteLine("Add({0},{1}) = {2}", value1, value2, result);

            // Call the Subtract service operation.
            value1 = 145.00D;
            value2 = 76.54D;
            result = client.Subtract(value1, value2);
            Console.WriteLine("Subtract({0},{1}) = {2}", value1, value2, result);

            // Call the Multiply service operation.
            value1 = 9.00D;
            value2 = 81.25D;
            result = client.Multiply(value1, value2);
            Console.WriteLine("Multiply({0},{1}) = {2}", value1, value2, result);

            // Call the Divide service operation.
            value1 = 22.00D;
            value2 = 7.00D;
            result = client.Divide(value1, value2);
            Console.WriteLine("Divide({0},{1}) = {2}", value1, value2, result);

            //Step 3: Closing the client gracefully closes the connection and cleans up resources.
            client.Close();

            Console.ReadLine();
        }
    }
}
