When i run my service it is failed to add Service?

Question

When i Run my Service it is showing error message .

Simple , i wrote a program using wcf....

In interface ITemperatureService.cs file i wrote this.....

using System;

using System.Collections.Generic;

using System.Linq;

using System.Runtime.Serialization;

using System.ServiceModel;

using System.ServiceModel.Web;

using System.Text;

// NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IService" in both code and config file together.

[ServiceContract]

public interface ITemperatureService

{

[OperationContract]

string GetTemperature(int faren);

}

then I Wrote in TemperatureService.cs file................

using System;

using System.Collections.Generic;

using System.Linq;

using System.Runtime.Serialization;

using System.ServiceModel;

using System.ServiceModel.Web;

using System.Text;

// NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "Service" in code, svc and config file together.

public class TemperatireService : ITemperatureService

{

public string GetTemperature(int faren)

{

return Convert.ToString(((faren - 32) / 9) * 5);

}

and i changed my setting in TemperatureService.svc file like.....

<%@ ServiceHost Language="C#" Debug="true" Service="TemperatureService" CodeBehind="~/App_Code/TemperatureService.cs" %>

But when i m running this Temperature.svc file i m getting the same error like this below

You need to add a metadata exchange (mex) endpoint to your service: address = mex binding = mexHttpBinding contract = IMetadataExchange />
