I have recently updated my project from Mvc 3 to Mvc 5 and we are trying to publish the app on an IIS server so that we may test it. But we have a nasty crash that always occurs and I do not know what provokes it and how to correct it.
Here's the stack trace:
Server Error in '/' Application.

So what puzzles me is that we do not have the System.Web.Razor packaged installed anymore. Rather, we have the System.Web.Razor version 3.0.0.0. Nonetheless, I have done everything suggested in this link on how to upgrade from mvc3 to mvc4 and all my packages are up-to-date.
I even tried to uninstall the Microsoft.Web.WebPages.OAuth package to see if it was the cause, but it is more resistant than a cockroach and I could not delete it without having an app that did not compile anymore. I need help resolving this case, my only next option would be to try to create a new app and reload all the stuff, which is kinda long and tedious.
