MVC 5 - VS Community 2015 - Routing not working?

It has to be something simple that I'm missing, since this is my first try on MVC. Seems nothing works but the default route.

This were my steps:

1. Create new solution from an MVC5 template (Which comes with a HomeController and a Controller/Action/Id by default on the RouterConfig.Configuration.
2. Add --> Controller named Foo --> Create an ActionResult named Details
3. Add a View named Details
4. Run the MVC project
5. Appears the home page, and I change the url from

localhost:50212

to

localhost:50212/Foo/Details

Result: I get a 404

Is it that the MVC AreaRegistration does not happen automatically on compile time?

I went to the Global.asax and tried placing on Application_Start

AreaRegistration.RegisterAllAreas();

But that seemed useless. Any Ideas? Is it that VS community 2015 is missing something? Regards
