title: Can't write directive in svc file
body: <p>It could be a dumb question but I need the solution.</p>
  
  <p>I would like to deploy my first REST web service in IIS by following this step : <a href="https://stackoverflow.com/questions/5747751/how-to-host-a-restful-wcf-web-service">How to Host a Restful WCF Web Service</a></p>
  
  <p>But I have a problem : I don't know how to write the directive in the svc file.
  There are 3 files :</p>
  
  <ul>
  <li>IService1.cs</li>
  <li>Service1.svc</li>
  <li>Service1.svc.cs</li>
  </ul>
  
  <p>I double clicked the Service1.svc but I always get Service1.svc.cs</p>
  
  <p>I can't find "View Designer" icon as I found in webform file.</p>
  
  <p>I build the project using Visual Studio 2008 SP1</p>
  
  <p>Would you please tell me what mistakes I did?</p>
  
  <p>Thanks in advance,
  Samuel</p>
