MVC.NET Routing works in development server but not on IIS 7.0

Question

I've upgraded our project from being a website to a web app and imported to VS2k10.

I've added the following references:

System.Web.Abstractions

System.Web.MVC

System.Web.Routing ...

Changed target framework to 4.0...

Added a controller 'HomeController.cs'... This now works in the development server but NOT in IIS 7.0

Windows Server 2k8 r2 VS2010 .net framework 4.0

Application pool is running in Integrated Pipeline mode... I'm a little confused over why it works in the dev server but not on IIS...

Sorry, forgot to mention. On dev server I get the expected response. Same URL in IIS I get: Error Summary HTTP Error 404.0 - Not Found The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.
