title: ASP.NET 4.0 app mapped through virtual folder on SharePoint 2010
body: <p>I'm considering publishing an an ASP.NET MVC 3 app under a SharePoint 2010 application <em>on IIS</em> (not inside SharePoint as a SPSite or whatnot, just a regular IIS application for SSO-integration w. SP).</p>
  
  <p>The MVC app would then only inherit some configs. It has no reference to SharePoint and SharePoint does not have any reference to it other than it being an sub application under the SharePoint 2010 app in IIS.</p>
  
  <p>3-fold question:</p>
  
  <p><ul>
  <li> Is it possible? </li>
  <li> Are there any obvious issues with SharePoint 2010 running on 3.5, and my new app running on 4.0 for instance? Sufficient to use different app-pools?
  </li>
  <li> I'm concerned about the inheritance of web.configs between my MVC app to SharePoint's 
  </li>
  </ul>web.config. Are there any issues regarding web.config inheritance between these two?</p>
