Explain the difference between ASP.NET Web Forms and ASP.NET MVC.

ASP.NET Web Forms follows a page-centric model, providing a set of controls to create rapid application development. It uses a stateful paradigm with server controls. On the contrary, ASP.NET MVC adopts a more modular and testable approach, separating concerns into models, views, and controllers. MVC is best suited for large and complex applications where control over HTML and JavaScript is crucial.
