Upgrading ASP.NET MVC via NuGet does not update Web.config files

I was recently upgrading a sample project from ASP.NET MVC 4 to ASP.NET MVC 5 via NuGet and when I examined my Web.config files, I noticed that none of the Web.config entries had been updated to match the newer version of ASP.NET MVC!

 

This was my original Web.config file at the root of the project:

 

<?xml version="1.0" encoding="utf-8"?>
