Are there big differences between versions of ASP.NET MVC?

Question

ASP.NET

Of course, you need to know ASP.NET MVC 5
But do you need to learn MVC 3 and MVC 4 before that ?
And what is the difference between them?
Can it be described in two words?

Answer 1

Yes, why are you soaring, learn the latest technology. And if you decide to learn directly from scratch, then take ASP.NET 5 and MVC 6 right away, they are still in the preview, but I think there will be a release pretty soon, in Update 1 or 2. And development for them will differ pretty well from the current workflow .
You would also ask if you need to know WebForms to learn MVC). Well, of course, if you know it will come in handy, for a general idea of ​​​​the development of technology, from which we came to what.

Answer 2

it is not necessary to study previous versions. ASP.NET MVC 5 has absorbed everything from mvc 4 and mvc 3, discarding everything obsolete and unnecessary. In a nutshell, in mvc 5 the built-in authorization system is different, plus there are additions.
