Editor's Notes
There have been a lot of rumors floating around that ASP.NET Web Forms is dying and being replaced with ASP.NET MVC…you know, like the Web Forms Reaper is coming? Well….here I am!
It is up to you to decide how you want to get your data and how to define your objects. Although there are accepted guidelines on how to have good design, it is not decided for you with The ASP.Net MVC Framework.
