title: All about WSDL vs MEX?
body: <p>I am not able to open the meta data url <code>http://localhost:8082/Tasks/mex</code>, even though
  I've added the mexHttpBinding in the config file. Can I view this MEX endpoint in a browser?</p>
  
  <p>The config files look like:</p>
  
  <pre><code>&lt;endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /&gt;
  </code></pre>
  
  <p><strong>Questions:</strong></p>
  
  <ul>
  <li>Is MEX is different from WSDL? If not, then why do we require a MEX endpoint over WSDL?</li>
  <li>In the WSDL, I see the WSDL type information is missing. Is it by default? Can I look at the type information in WSDL?</li>
  </ul>
