How to Create WCF Service

First create class Library project and name it as SERVICE_DRAGON. Then   add WCF service to this class library project and name it as Service_Winows.When add the wcf file it will create clas file and interface file and also added System.serviceModel assembly..in this file create Service_Winows and IService_Winows.

          Now we will create simple method to print name with hello wold in interface class and implement it in class file.

Ø  IService_Winows

namespace SERVICE_DRAGON

{

    [ServiceContract(Name ="DoService")]

    public interface IService_Winows

    {

        [OperationContract(Name ="GetName")]

        string  DoWork(string Name);

    }

}

Ø  Service_Winows

namespace SERVICE_DRAGON

{

    public class Service_Winows : IService_Winows

    {

        public string DoWork(string Name)

        {

            return Name;

        }

    }

}

Now we have to host this service, for doing this we can use following method.

ü  Using windows form

ü  Using windows service

ü  Using console application

ü  Using IIS

  

In this tutorial we will use console application to host service.

Create console application and name it as ServiceHostSer and add this code snippet to it

namespace ServiceHostSer

{

    class Program

    {

        static void Main(string[] args)

        {

            using (ServiceHost host = new ServiceHost(typeof(SERVICE_DRAGON.Service_Winows)))

            {

               

                host.Open();

                Console.WriteLine(System.DateTime.Now);

                Console.ReadLine();

            }

        }

    }

}

Then we have to configure endpoint to relevant communication media to send data. We can do this in console application app.conifg file.

<system.serviceModel>

    <services>

      <service name="SERVICE_DRAGON.Service_Winows" behaviorConfiguration="mexBehavior">

        <endpoint address="Create_WCF_Service" binding="basicHttpBinding" contract="SERVICE_DRAGON.IService_Winows">

        </endpoint>

     

        <endpoint address="Create_WCF_Service" binding="netTcpBinding" contract="SERVICE_DRAGON.IService_Winows">

        </endpoint>

        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange">

        </endpoint>

        <host>

          <baseAddresses>

            <add baseAddress="http://localhost:8083/"/>

            <add baseAddress="net.tcp://localhost:8080/"/>

          </baseAddresses>

        </host>

      </service>

    <behaviors>

      <serviceBehaviors>

        <behavior name="mexBehavior">

          <serviceMetadata httpGetEnabled="true"/>

        </behavior>

      </serviceBehaviors>

    </behaviors>

  </system.serviceModel>
