I\'m running Windows 7 Ultimate (64 bit) using Visual Studio 2010 RC. I recently decided to have VS run/debug my apps on IIS rather than the dev server that comes with it. <
For me on an Azure Server 2012 R2 IIS 8.5 VM with an Asp.Net MVC 5 app (bin deployed MVC 5) I had to do the following from an elevated cmd prompt even though I had 4.5 already installed:
dism /online /enable-feature /featurename:IIS-ASPNET45

I also brute force installed all IIS features with the following PowerShell:
import-module servermanager
add-windowsfeature web-server -includeallsubfeature

Now my app is working.
