Why does my MVC 4 Project Partially Run on Production IIS 7 Server <p>We have a ASP.NET MVC 4 project containing a number of controllers, models and views. </p> <p>On our development server a Windows Standard 2008 (x64) the project is deployed/published and it runs fine. </p> <p>However, when we try to publish the project to our live production server running a Windows Web 2008 x64 the MVC pages appear to partially load, but when we try to make calls to the controller it appears that it is failing. </p> <p>It is very difficult for me to give more information, since I don't know where to trap the error or how to diagnose the problem.</p> <p>Any help would be greatly received.</p>
