title: Application Pool Mode Problem: Classic Or Integrated
body: <p>I am facing an issue and was hoping if you could please provide me with some guidance:</p>
  
  <ol>
  <li><p>I have a Asp.net 4.0 website application that uses spring.net and ext.net libraries.  I have deployed it in IIS 7 using <strong>classic</strong> application pool mode and it works.  <strong>It doesn't work in integrated mode</strong>.</p></li>
  <li><p>I have another Asp.net 4.0 silverlight website application that is deployed in IIS 7 using <strong>integrated</strong> application mode and it works.  <strong>It doesn't work in classic mode</strong>.</p></li>
  </ol>
  
  <p>I have created a new ASP.net web application that combines both of the 1 and 2 web applications above.  It uses Ext.Net, Spring.Net and Silverlight 4.0.  In Visual Studio's web server, when I run it in debug mode, it works perfectly.</p>
  
  <p>When I deploy it in IIS 7, it doesn't work.  How can I make the application run in one mode?  Is there a web.config setting that can define the parts of the website to run under a different application pool mode?</p>
