Problem with MVC3 updgrade. Update to MVC3 from MVC2 Web App Solution, possible?

I tried upgrading the solution to MVC3 in VS2010 by using an upgrader tool

I don't know what it does exactly but it didn't work. My "System.Web.Mvc" is not being recognized in my project.

Is there anything specific I should be doing with my web.config? I don't quite understand the underlying details about all the places I should be referencing dll's or what "binding" even means and when I should use it inside the web.config

So I have to ask, what is the best method for upgrading to MVC3 and what have you done that works?

Thanks a b开发者_运维技巧unch friends.

You mean the reference? What happens if you delete the reference from the project and add it back from the file location where you installed MVC3?
