IMetadataExchange issue in WCF

I am using VSTS 2010 + C# + .Net 4.0 + IIS 7.5 + Windows 7. I am following MSDN sample here without any modifications, http://msdn.microsoft.com/en-us/library/ms733766.aspx

When I open the service.svc file (in IIS manager, right 开发者_C百科click the svc file and select browse) in IIS, there is an error like this, any ideas what is wrong?

in the service list CalculatorService not find the protocol name "IMetadataExchange". Add ServiceMetadataBehavior to the configuration file or directly add to the ServiceHost

Here is the web.config I am using,

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.serviceModel>
    <services>
      <!-- This section is optional with the default configuration
        model introduced in .NET Framework 4 -->
      <service name="Microsoft.ServiceModel.Samples.CalculatorService">

        <!-- This endpoint is exposed at the base address provided by host:                                        http://localhost/servicemodelsamples/service.svc  -->
        <endpoint address=""
                  binding="wsHttpBinding"
                  contract="Microsoft.ServiceModel.Samples.ICalculator" />

        <!-- The mex endpoint is exposed at http://localhost/servicemodelsamples/service.svc/mex -->
        <endpoint address="mex"
                  binding="mexHttpBinding"
                  contract="IMetadataExchange" />
      </service>
    </services>
  </system.serviceModel>

</configuration>

Try adding this to behavior to Config file:

<behaviors>
      <serviceBehaviors>
        <behavior name="CalculatorServiceBehavior">
          <serviceMetadata httpGetEnabled="True"/>
          <serviceDebug includeExceptionDetailInFaults="False" />
        </behavior>
      </serviceBehaviors>
    </behaviors>

and change the service element to ADD this behavior :

<service 
          name="Microsoft.ServiceModel.Samples.CalculatorService"
          behaviorConfiguration="CalculatorServiceBehavior">
