WCF Service Console Host and Console Client

Below are the classes and interface to host a service

ICalculator.cs

using System;

using System.ServiceModel;

namespace Interface

{

    [ServiceContract]

    public interface ICalculator

    {

        [OperationContract]

        double Add(double num1, double num2);

        [OperationContract]

        double Subtract(double num1, double num2);

        [OperationContract]

        double Multiply(double num1, double num2);

        [OperationContract]

        double Devide(double num1, double num2);

    }

}

CalculatorService.cs
using System;

namespace Service

{

    public class CalculatorService : Interface.ICalculator

    {

        public double Add(double num1, double num2)

        {

            return num1 + num2;

        }

        public double Subtract(double num1, double num2)

        {

            return num1 - num2;

        }

        public double Multiply(double num1, double num2)

        {

            return num1 * num2;

        }

        public double Devide(double num1, double num2)

        {

            return num1 / num2;

        }

    }

}

Host.cs
using Interface;

using Service;

using System;

using System.ServiceModel;

namespace ConsoleHost

{

    class Host

    {

        static void Main(string[] args)

        {

            //ServiceHost host = new ServiceHost(typeof(CalculatorService));

            ServiceHost host = new ServiceHost(typeof(CalculatorService), new Uri("http://localhost:8888/test"));

            host.AddServiceEndpoint(typeof(ICalculator), new NetTcpBinding(), "net.tcp://localhost:8889/test");

            //host.AddServiceEndpoint(typeof(ICalculator), new WSHttpBinding(), "http://localhost:8888/test1");

            host.AddDefaultEndpoints();

            host.Open();

            Console.WriteLine("Listening at ...");

            int i = 0;

            foreach (var ep in host.Description.Endpoints)

            {

                Console.WriteLine("({0}) A: {1}, \tB: {2}, \tC: {3}", i, ep.Address, ep.Binding.Name, ep.Contract.Name);

                i++;

            }

            Console.WriteLine("Service is running ... Press any key to stop service.");

            Console.ReadKey();

            host.Close();

        }

    }

}

Below are the classes and configuration to access the above hosted service.

App.config
<xml version="1.0" encoding="utf-8" ?>

<configuration>

  <startup>

    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.2" />

  </startup>

  <system.serviceModel>

    <client>

      <endpoint name="basicEP" address="http://localhost:8888/test" binding="basicHttpBinding" contract="Interface.ICalculator" />

      <endpoint name="netTcpEP" address="net.tcp://localhost:8889/test" binding="netTcpBinding" contract="Interface.ICalculator" />

    </client>

  </system.serviceModel>

</configuration>

Client.cs
using Interface;

using System;

using System.ServiceModel;

using System.ServiceModel.Description;

namespace ConsoleClient

{

    class Client

    {

        static void Main(string[] args)

        {

            /*

            ChannelFactory factory = new ChannelFactory();

            factory.Endpoint.Address = new EndpointAddress("http://localhost:8888/test");

            factory.Endpoint.Binding = new BasicHttpBinding();

            factory.Endpoint.Contract = ContractDescription.GetContract(typeof(ICalculator));

            */

            ChannelFactory<ICalculator> factory = new ChannelFactory<ICalculator>("netTcpEP"); //provide endpoint name defined in App.config

           

            ICalculator proxy = factory.CreateChannel();

            Console.WriteLine(proxy.Add(12, 22));

            Console.ReadKey();

        }

    }
