6.  Ruby on Rails  Django and Python  Spring, Struts and Java  Zend Framework and PHP  MonoRail  … ASP.NET MVC – Hands on 6 MVC ON THE WEB TODAY

7.  Separation of application tasks (input logic, business logic, and UI logic), testability, and test-driven development (TDD) by default  An extensible and pluggable framework  A powerful URL-mapping component that lets you build applications that have comprehensible and searchable URLs  Convention over configuration  Don’t repeat yourself, keep it simple (DRY/KISS principles) ASP.NET MVC – Hands on 7 ASP.NET MVC

8. ASP.NET MVC – Hands on 8 TIMELINE ScottGu sketched out the core of ASP.NET MVC (~100 lines of code) February 2007 Presenstation of Scalene at the Austin ALT.NET conference September 2007 First Community Technology Preview December 2007 ASP.NET MVC 1.0 March 2009 ASP.NET MVC source code was released under the MS-PL April 2009 ASP.NET MVC 2.0 Shipped with Visual Studio 2010 March 2010 ASP.NET MVC 3.0 Shipped with Visual Studio 2010 January 2011

9. 9 ASP.NET MVC – Hands on COMPARISON WITH ASP.NET WEB FORMS

10.  Represent a Page as control tree  Give these server-side controls events like their desktop counterparts  Hide as much HTTP and HTML as is reasonable  Make state management as transparent as possible ASP.NET MVC – Hands on 10 WHAT WEB FORMS DOES WELL

11.  ViewState is powerful, but it has its drawbacks (weight,…)  Page life cycle can be a nightmare  Limited control over HTML  Client IDs and the ctl00$ContentPlaceHolder1$UserControl1$TextBox1 syndrome  It’s nearly impossible to run a Web Form through its life cycle outside IIS ASP.NET MVC – Hands on 11 WHERE WEB FORMS DOESN’T FIT

12.  Guiding tenets:  Be extensible, maintainable, and flexible  Be testable  Get out of the user’s way when necessary  Serving methods, not files  Separation of concerns  ScottHa said: « ASP.NET MVC is Web Forms unplugged » ASP.NET MVC – Hands on 12 ASP.NET MVC BELIEVES

13.  ASP.NET MVC is built on top of ASP.NET  ASP.NET MVC is not a replacement for anything  It is just an alternative  It’s a totally different approach SHOULD YOU FEAR ASP.NET MVC? ASP.NET MVC – Hands on 13
