Question

What is difference between MVC and Web Forms?

Answer 1

ASP.Net MVC / Web Forms difference

 

The following are some difference.

 

ASP.Net MVC	ASP.Net Web Forms
View and logic are separate, it has separation of concerns theory. MVC 3 onwards has .aspx page as .cshtml.	No separation of concerns; Views are tightly coupled with logic (.aspx.cs /.vb file).
Introduced concept of routing for route based URL. Routing is declared in Global.asax for example.	File-based routing .Redirection is based on pages.
Support Razor syntax as well as .aspx	Support web forms syntax only.
State management handled via Tempdata, ViewBag, and View Data. Since the controller and view are not dependent and also since there is no view state concept in ASP.NET, MVC keeps the pages lightweight.	State management handled via View State. Large viewstate, in other words increase in page size.
Partial Views	User Controls
HTML Helpers	Server Controls
Multiple pages can have the same controller to satisfy their requirements. A controller may have multiple Actions (method name inside the controller class).	Each page has its own code, in other words direct dependency on code. For example Sachin.aspx is dependent on Sachin.aspx.cs (code behind) file.
Unit Testing is quite easier than ASP.Net Web forms Since a web form and code are separate files.	Direct dependency, tight coupling raises issues in testing.
layouts	Master pages
