“If people want to have maximum reach across *all* devices then HTML will provide the broadest reach”
Scott Guthrie, Corporate Vice President, Microsoft
ObjectivesWhy MVC?ASP.NET MVC In DetailBetter IntegrationConclusions
PrerequisitesASP.NET DeveloperGood understanding of HTML and HTTPGood understanding of C# 3.0 LanguageNo MVC Experience is required
Quick DemoCreate new MVC ProjectCreate new controllerCreate new View
Web Development TodayBrowsing experience everywhereGreater variety of devices and browsersIncreasing drive for web standards
HTML5CSS3
Multidiscipline Web ServerHTML GenerationData ServicesService Orientation
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
Classical ASP.NETHuge shift at that timeObject oriented approachCompiled web pagesStateful UIEvent DrivenDrag and Drop DesignerWindows Forms Developing ExperienceIs here to stay !!!
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
DemoIntroduction to PhoneBook BLAdd GroupControllerPass model object to view Add Group.Index ViewConfigure RoutingSupport clickingOutgoing URLUse ViewData
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)
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
Controller Base ClassActionAction resultFilters
[OutputCache(Duration=600, VaryByParam”*”)]public class DemoController : Controller{
public ViewResult ShowGreeting(){
return View(“MyView”);}
}
Controller – Producing OutputTypes of action results
ViewPartialViewRedirectJsonJavaScriptFileContentOthers
DemoSubmitting data to the controllerUse action filters (GET, POST)Model BindingValidation
Controller - Receiving InputUse context objects
HttpContextRouteDataTempData
Implicit model bindingThrough action parametersEasier to test
Explicit model bindingFull control
Model BindingIs built from
FormRouteDataQueryString
The DefaultModelBinderConverts strings into .NET objectsUses .NET “Type Converter” facility

Inject extra logicGreat from testing perspective

Questions ?
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?
