The following are the differences between web forms and asp.net mvc
• Web Forms is hard to test as compared to ASP.NET MVC application
• ASP.NET MVC requires you to specify every little bit of HTML as comared to web forms.
• The Separation of Concerns (SoC) is not proper in Web Forms Development. In MVC there is a clear separation between your UI and code.
• Web Forms was designed to abstract the Web machinery whereas ASP.NET MVC was designed with testability and DI in mind
• ASP.NET MVC takes you towards a better design of the code
• ASP.NET MVC is not Event Driven where asp.net web forms use events.
• ASP.NET MVC does not have third party control support.Web forms provide rich support for third party controls.
• In Web Forms to achieve statefulness, state of every page stored in viewstate which often rendered on client page as a hidden field.
• In ASP.NET MVC no viewstate is ever required to persist the state of the page.
• In Web Forms the post back model of ASP.NET page makes it harder for search engines to rank the page. No posback is needed in ASP.NET MVC.
