Answer 1

Did you actually configure a mex endpoint for your service?

That would look something like this:

<service name="MyService" ...>
    <!-- actual service endpoints here -->
    <endpoint address="/mex" binding="mexHttpBinding" contract="IMetadataExchange" />
</service>

Answer 2

I am using visual studio 2008 and framework 3.5

And that is the whole problem. The example you are referring is for WCF 4 which uses something called default endpoints or simplified configuration. Nothing like this exists in WCF 3.5. You must manually configure your service and all its endpoints!

<system.serviceModel>
  <services>
    <service name="EmailService.EmailValidator" behaviorConfiguration="Metadata"> 
      <host>
        <baseAddresses>
          <add baseAddress="http://localhost:8080/" />
        </baseAddresses>
      </host>
      <endpoint address="" binding="basicHttpBinding" contract="EmailService.IEmailValidator" />
      <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
    </service>
  </services>
  <behaviors>
    <serviceBehaviors>
      <behavior name="Metadata">
        <serviceMetadata httpGetEnabled="true" />
      </behavior>
    </serviceBehaviors>
  </behaviors>
</system.serviceModel>
