title: 'System.Web.Extensions' trouble deploying .Net Framework 4 Website on IIS7
body: <p>I am trying to deploy a .Net framework 4 website on IIS7 server. I have already changed the application-pool's target framework to .Net 4, but the app is still showing me the error:</p>
  
  <p><em>"The configuration section 'system.web.extensions' cannot be read because it is missing a section declaration"</em></p>
  
  <p>I am guessing that has something to do with the new feature of .Net4 that lets me have a compact Web config file. I think for some reason IIS7 is not happy with this.</p>
  
  <p>What can I do to deploy this app successfully or do I have to scale back to v3.5? I am sure there is a solution out there.</p>
  
  <p>Do you have any suggestions?</p>
