title: WCF service hosting in IIS 7.5 - The page you are requesting cannot be served because of the extension configuration
body: <p>Whenever I publish WCF service to IIS. It is almost I have become habituated to get this error:</p>
  
  <blockquote>
    <p>HTTP Error 404.3 - Not Found The page you are requesting cannot be
    served because of the extension configuration. If the page is a
    script, add a handler. If the file should be downloaded, add a MIME
    map.</p>
  </blockquote>
  
  <p>The practice I have maintained: is to change application pool for the website to <code>classic mode</code>.
  But this time I am out of luck. </p>
  
  <ul>
  <li>Q.1. Can you please help?</li>
  <li>Q.2. As the error suggests: Should I configure .svc MIME map some
  where in IIS?</li>
  <li>Q.3. For WCF to operate in integrated pipeline mode, Is there any specific
  configuration required?</li>
  </ul>
