So you need to update from MVC 3.0.0.0 to MVC 3.0.0.1 or should I say your windows update tool caused you to update.

Refer to this article

Then open package manager for nuget and make sure it is pointed to the correct project..

Usually your root mvc application

Then type in the console :  get-package

It will list out your installed packages

See if your framework number is: 3.0.50813.1 for Microsoft.AspNet.Mvc

if not, then you will need to update your solution projects

The COmmand is:  Install-Package Microsoft.AspNet.Mvc -Version {hit the tab key.. find the version you need – in my case 3.0.50813.1} and select it.. Run it and you should be done…

Note you might get a sql lite issue.. See https://warrenlafrance.com/2016/03/08/sql-lite-error/
