18. ASP.NET MVC Key Versions ASP.NET MVC 3 2011 ASP.NET MVC 2 2010 ASP.NET MVC 1 2009 ASP.NET

19. ASP.NET Components Web Forms View Engine Razor View Engine ASP.NET Web Forms ASP.NET MVC ASP.NET Core Caching Pages Handlers Roles Modules Controls Profile Security Globalization Master Pages Membership Etc.

20. Sample Application

21. Concept Project name: “Easy Reporting” Idea: time tracking system for developers

22. Key Use Cases

23. Components

24. Basic Concepts of MVC Project

25. Typical MVC Project Structure

26. Simple Controller and Action ProjectController.cs Controller Action

27. Simple View Index.cshtml

28. Simple Client Page

29. Mediator MVC Implementation Client Controller View Action Model

30. ASP.NET MVC Key features

31. Action Results ActionResult – base class of result of an action View Redirect JavaScript Json File HTTP Content Empty

33. Action

34. Controller

35. ApplicationAction Filter Action Standard filters: Authorize HttpGet HttpPost OutputCache HandleError Action Filter

36. Action Filters: Example ProjectController.cs

37. View Engines Concept Razor ASP.NET MVC *.aspx / *.ascx / *.master Etc.

38. Passing data into View Action View Model ViewData ViewBag TempData

39. HTML Helpers HTML Helper – “server control” in ASP.NET MVC Classic HTML Helpers Declarative HTML Helpers

40. Partial Views Partial view – “user control” in ASP.NET MVC Footer.cshtml _Layout.cshtml Header.cshtml

41. Layout pages and sections Layout page – “master page” in ASP.NET MVC Section – “ContentPlaceHolder” in ASP.NET MVC

42. Routing Controller Client URL Routing Engine Action Params Default route - /controller/action/id

43. Dependency Injection IServiceLocator MvcServiceLocator Setup Controller Factory Implement Controller Service Locator Implementation Instantiate Action Filter View

44. Unit Testing TestableApplication UsingInversion of Control principle Can be tested: Controllers Routes Html helpers UI Models View logic Etc.

45. MVC Control Libraries Client Side Controls JQuery IU DOJO Etc. Server Side Controls Telerik DevExpress Etc.

46. MVC VS WebForms

47. When we do not need MVC? I need MVC, because … it is better than Web Forms … it implements MVC architecture … I want to escape from view state … I donot want automatically generated id in HTML … I want to get full control over HTML … I want more friendly URLs

48. MVC Benefits Automated testing Powerful AJAX client side Flexibility, extensibility, clarity Easy of learning and easy of using Clearly separated client side and server side

49. MVC Disadvantages Speed of development (particularly in early stages) … but you can win when you make changes in finished product

50. Conclusion ASP.NET MVC Convenient Easier Clearer Faster
