ASP.NET MVC 4
I have experience building web apps in Classic ASP, ASP.NET Web Forms, and ASP.NET MVC. Professionally, I currently work with both Web Forms and MVC, but MVC is my favorite. I love the clean separation of concerns
between the model, view, and controller layers. And I love that MVC views give you full control over your HTML markup, wich makes working with jQuery, CSS 3, KnockoutJs templates, JQuery Mobile, etc. much easier.
