Are you building your website in release mode before deploying? — Shashank Chaturvedi, Mar 27 '14 at 12:28
Try release mode and publish the site you will get to the real problem. — Shashank Chaturvedi, Mar 27 '14 at 12:51
Answer is for newer VS version, but in case of IIS Express the problem might be the same: http://stackoverflow.com/a/44083158/717732 — quetzalcoatl, May 20 '17 at 07:35
