PRESENTATION

5.  The MVC pattern is 30+ years old!
 It is a powerful and elegant means of separating concerns
 It makes it easier to test application
 It promotes parallel development thanks to the loose
coupling between the three main components
ASP.NET MVC – Hands on 5
WHAT IS MVC?

6.  Ruby on Rails
 Django and Python
 Spring, Struts and Java
 Zend Framework and PHP
 MonoRail
 …

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)

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?

THE MVC PATTERN

15.  Model
 objects are the parts of the
application that implement
the logic for the application’s
data domain
 View
 components that display the
application’s user interface
 Controller
 components that handle user
interaction, work with the
model, and ultimately select a
view to render
ASP.NET MVC – Hands on 15
THE MVC PATTERN

16.  Business logic and validation of the application’s data
domain
 Totally independant from the views or the controllers
 Model state can be stored in memory, database, XML files,…
ASP.NET MVC – Hands on 16
MODEL

17.  Application’s user interface using data from the model
 No interaction with the models or the controllers
 Views can be strongly typed
 Almost no code
ASP.NET MVC – Hands on 17
VIEW

18.  Handle user interaction
 Query the model
 Select the right view to render
