  <p>
  I'm using framework 2.0 and Visual Studio 2005.
  My web.config content is : 
  </p>
  
  <pre><code>&lt;system.net&gt;
      &lt;defaultProxy&gt;
          &lt;proxy usesystemdefault="true"/&gt;
      &lt;/defaultProxy&gt;
  &lt;/system.net&gt;
  </code></pre>
  
  <p>My computer has installed:</p>
  
  <ul>
  <li>Microsoft .NET Framework 2.0 Service Pack 2</li>
  <li>Microsoft .NET Framework 2.0 SDK-ENU</li>
  <li>( Framework 1.1 , 3,5 and 4.0 )</li>
  </ul>
  
  <p>I tested :</p>
  
  <p>
  <li>
  My current working folder is in a localdriver ,and this folder isn't shared.
  </li>
  <li>
  I set all permisions to this folder to my current user.
  </li>
  <li>
  Repair Framework 2.0 ( Windows add and remove programs )
  </li>
  <li>
  Other people in development team doesn't have problem when connect to WCF.
  </li>
  <li>

  </li>
  <li>
  Also If I Try to create new blank WCF service and try to connect , I get the same error.
  </li>
  <li>
  I CAN  show service when I type service url in a browser ( no connection problems )
  </li>
  <li>
  Firewall and Antivirus software in my local machine is disabled.
  </li>
  <li>
  If I try to connect to service via svcutil.exe "http://server:8080/Service.svc?wsdl" , I get the same error. ( Can't create web/proxy... )
  </li></p>
  
  <p>
  I suspect that error description doesen't represent the real problem.
  What are the main causes of this error?
  </p>
  
  <p>
  It's possible that missing some additional software?
  </p>

  Thanks for all in advance!
