ASP.NET MVC: ActionNameSelector and ActionMethodSelector (or another approach to submit form to multiple action methods) – Part I

At work I have recently faced a requirement to post a single form to multiple Action methods in a controller based on the context. For example, in the view there is a Form and there are several radio buttons; now my form should be posted to the Action method based on the radio button selection.
