Create WCF Service

Create WCF service. Open visual studio select new project and then from WCF tab select WCF Service application to create a new WCF service.

Delete the default code created by WCF from IService1 and Service1.svc.cs

a. So delete the data contract

b. Modify the service contract as below. Just make one operation contract to return a string .

IService1.cs

using System;

using System.Collections.Generic;

using System.Linq;

using System.Runtime.Serialization;

using System.ServiceModel;

using System.ServiceModel.Web;

using System.Text;

namespace WcfService5

{

    [ServiceContract]

    public interface IService1

    {

        [OperationContract]

        string GetMessage();

    }   

}

Service1.svc.cs

using System;

using System.Collections.Generic;

using System.Linq;

using System.Runtime.Serialization;

using System.ServiceModel;

using System.ServiceModel.Web;

using System.Text;

namespace WcfService5

{

    public class Service1 : IService1

    {

        public string GetMessage()

        {

            return "Hello From WCF Service "; 

        }

    }

}
Leave the default configuration created by WCF.

Web.Config

<?xmlversion="1.0"?>

<configuration>

  <system.web>

    <compilationdebug="true"targetFramework="4.0" />

  </system.web>

  <system.serviceModel>

    <behaviors>

      <serviceBehaviors>

        <behavior>         

          <serviceMetadatahttpGetEnabled="true"/>         

          <serviceDebugincludeExceptionDetailInFaults="false"/>

        </behavior>

      </serviceBehaviors>

    </behaviors>

    <serviceHostingEnvironmentmultipleSiteBindingsEnabled="true" />

  </system.serviceModel>

 <system.webServer>

    <modulesrunAllManagedModulesForAllRequests="true"/>

  </system.webServer>  

</configuration>
