This worked for me    Delete the originally created site  Recreate the site in IIS Clean solution Build solution   Seems like something went south when I originally created the site   I hate solutions that are similar to  Restart your machine  then reinstall windows  without knowing what caused the error   But  this worked for me   Quick and simple   Hope it helps someone else

This issue is caused by the pipeline mode in your Application Pool setting that your web site is set to   Short   Simple way Change the Application Pool mode to one that has Classic pipeline enabled  Correct way Your web config   web app will need to be altered to support Integrated pipelines  Normally this is as simple as removing parts of your web config  Simple way  bad practice  Add the following  to your web config  See http   www iis net ConfigReference system webServer validation    lt system webServer gt        lt validation validateIntegratedModeConfiguration  false    gt    lt  system webServer gt     Long If possible  your best bet is to change your application to support the integrated pipelines  There are a number of changes between IIS6 and IIS7 x that will cause this error  You can find details about these changes here http   learn iis net page aspx 381 aspnet-20-breaking-changes-on-iis-70    If you re unable to do that  you ll need to change the App pool which may be more difficult to do depending on your availability to the web server    Go to the web server Open the IIS Manager Navigate to your site Click Advanced Settings on the right Action pane Under Application Pool  change it to an app pool that has classic enabled    Check http   technet microsoft com en-us library cc731755 WS 10  aspx for details on changing the App Pool  If you need to create an App Pool with Classic pipelines  take a look at http   technet microsoft com en-us library cc731784 WS 10  aspx  If you don t have access to the server to make this change  you ll need to do this through your hosting server and contact them for help   Feel free to ask questions
