Web Development TodayRich Client Side Experience

Did we say HTML5?Easy integration with client side libraries

AgileTest Driven Development

REST over SOAPClean URLs

Ruby on RailsYear 2004MVC basedBuilt-in ORM tool

Page 9: Introducing ASP.NET MVC

Classical ASP.NETHuge shift at that timeObject oriented approachCompiled web pagesStateful UIEvent DrivenDrag and Drop DesignerWindows Forms Developing ExperienceIs here to stay !!!

Page 10: Introducing ASP.NET MVC

What’s wrong with it?Is “Windows Forms” approach suited?Limited control over HTMLEncourages mixing of presentation and logicHard to testViewStateComplex page life cycleHard to integrate with other libraries

ASP.NET MVCSeparation of concernsBuilt on top of ASP.NET platformTight control over HTMLDesigned to be testableExtensible routing systemBetter integration with 3rd party librariesOpen sourceLanguage innovations

MVC IngredientsRouting SystemControllerActionFilterViewModelModel StateView Data

Page 15: Introducing ASP.NET MVC

DemoIntroduction to PhoneBook BLAdd GroupControllerPass model object to view Add Group.Index ViewConfigure RoutingSupport clickingOutgoing URLUse ViewData

Page 16: Introducing ASP.NET MVC

Routing SystemMakes your URLs clean and human friendlyNo correspondence between files and URLsInbound URLOutgoing URLImplemented by System.Web.Routing.dll

Originally shipped with .NET 3.5 SP1You can use it in your classical ASP.NET 4.0

web pagesWas merged into System.Web.dll (starting 4.0)

Page 17: Introducing ASP.NET MVC

ControllerThe controller is the bossResponsible for application logic

Receiving user inputWork against the domain modelMoving the user between different UI

Implements IControllerSingle method: Execute

Usually derives from Controller

Page 18: Introducing ASP.NET MVC

Controller Base ClassActionAction resultFilters

[OutputCache(Duration=600, VaryByParam”*”)]public class DemoController : Controller{

public ViewResult ShowGreeting(){

return View(“MyView”);}


Page 19: Introducing ASP.NET MVC

Controller – Producing OutputTypes of action results


Page 20: Introducing ASP.NET MVC

DemoSubmitting data to the controllerUse action filters (GET, POST)Model BindingValidation

Page 21: Introducing ASP.NET MVC

Controller - Receiving InputUse context objects


Implicit model bindingThrough action parametersEasier to test

Explicit model bindingFull control

Page 22: Introducing ASP.NET MVC

Model BindingIs built from


The DefaultModelBinderConverts strings into .NET objectsUses .NET “Type Converter” facility

DemoAdd Master PageAdd Partial View

Page 24: Introducing ASP.NET MVC

DemoAdd Authentication filterImplement custom filterRegister global filter

Page 25: Introducing ASP.NET MVC

Action FilterAttach reusable behavior


Inject extra logicGreat from testing perspective

Action filter implements IActionFilterResult filter implements IResultFilterActionFilterAttribute implements both

Questions ?

Page 30: Introducing ASP.NET MVC

ConclusionsA different way to develop web applications

Hopefully, better“Semi” WOW effect

Long term benefitsFeel natural

No rich server control libraryBe ready to integrate other libraries

You must know HTTP and HTML goodWhat about client side MVC?
