Solution:

In your pc you have the following folder: C:\Program Files (x86)\Microsoft ASP.NET\ASP.NET MVC 3\Assemblies

Inside you have System.Web.Mvc.dll in this case this file was version 3.0.0.1

So when you compile in your Vs2017 your project, it references to this folder and to that particular file.

So just find older version of System.Web.Mvc.dll (3.0.0.0) somewhere and put it in that directory, and finally recompile your project. Now it will references to the proper version.

It wont say in Properties of that file 3.0.0.0, it will be somthing like:

Product version: 3.0.20105.0

Before:

Product version: 3.0.50813.1

In my case to obtain older version i took directly from the project BIN filder from production environment.
