host wcf service in windows service

Step 1)  Create Windows Service Application As shown below

Step 2)  Add references
                 1) System.ServiceModel
                 2) System.ServiceProcess

Step 3)  Add new class WsHost.cs (for wcf interface + implementation)

  FileName: wsHost.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;
using System.Runtime.Serialization;


namespace WindowsService1
{
    [ServiceContract]
    interface IOrder1
    {
        [OperationContract]
        int GetOrderCount();
        [OperationContract()]
        string getCustomername();

    }
    public     class wsHost:IOrder1
    {
        public int GetOrderCount()
        {
            return 100;
        }

        public string getCustomername()
        {
            return "Customer Name is jhon peter paul";
        }
    }
}

Step 4) Implement Service host in derived ServiceBase class

FileName:Service1.cs

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Diagnostics;

using System.Linq;

using System.ServiceProcess;

using System.Text;

using System.ServiceModel;

namespace WindowsService1

{

    public partial class Service1 : ServiceBase

    {

        ServiceHost host = null;

        public Service1()

        {

            InitializeComponent();

        }

        protected override void OnStart(string[] args)

        {

            if (host != null) host.Close();

            host = new ServiceHost(typeof(wsHost),

                new Uri("http://localhost:111/wsHost"));

            host.Open();

        }

        protected override void OnStop()

        {

            if (host != null) host.Close();

            host = null;

        }

    }

}

Step 5) Implement Installer class

After adding installer.cs

replace with the following content

using System;

using System.Collections;

using System.Collections.Generic;

using System.ComponentModel;

using System.Configuration.Install;

using System.Linq;

using System.ServiceProcess;

namespace WindowsService1

{

    [RunInstaller(true)]

    public partial class Installer1 : System.Configuration.Install.Installer

    {

        ServiceProcessInstaller process;

        ServiceInstaller service;

        public Installer1()

        {

            InitializeComponent();

            process = new ServiceProcessInstaller();

            process.Account = ServiceAccount.LocalSystem;

            service = new ServiceInstaller();

            service.ServiceName = "WCF host in Windows Service";

            service.Description = "Hosting wcf service in Windows Service";

            service.StartType = ServiceStartMode.Automatic;

            Installers.Add(process);

            Installers.Add(service);

        }

    }

}

Step 6)  Add application config & change copy to output directory option as shown below.

replace  app.config content

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

<configuration>

  <system.serviceModel>

    <behaviors>

      <serviceBehaviors>

        <behavior name="MyserBehaviour">

          <serviceDebug  includeExceptionDetailInFaults="true"/>

          <serviceMetadata httpGetEnabled="true"/>

        </behavior>

      </serviceBehaviors>

    </behaviors>

    <services>

      <service name="WindowsService1.wsHost" behaviorConfiguration="MyserBehaviour">

        <endpoint contract="WindowsService1.IOrder1" binding="basicHttpBinding"></endpoint>

      </service>

    </services>

  </system.serviceModel>

</configuration>

Step 7)  Open VS2010 Command Prompt

  got application folder bin directory  in this case "c:\users\administrator\documents\visual studio 2010\Projects\WindowsService1\WindowsService1\bin\debug"

c:\Users\Administrator\Documents\Visual Studio 2010\Projects\WindowsService1\Win
dowsService1\bin\Debug>installutil WindowsService1.exe

Installutil.exe is used for installing Windows Services 

Step 8)  Goto Service Manager as shown below

It will display all services in the system, select "Wcf Host in Windows Service"  and start the service

Step 9) Open Browser  and type "http://localhost:111/wshost"

OUTPUT

TEST  ALL METHODS WITH   WCFTESTCLIENT

Open VS2010 command prompt type 

WcfTestClient

i.e c:>  wcftestclient.exe

and then  give above url/add service  http://localhost:111/wshost
