Introduction to mvc architecture
- 2. INTRODUCTION TO MVC ASP.NET ARCHITECTURE ASP.NET MVC is a part of ASP.NET and not an entirely separate Framework. The Model-View-Controller (MVC) pattern is an architectural design principle that separates the components of a Web application. This separation gives you more control over the individual parts of the application, which lets you more easily develop, modify, and test them. ASP.NET MVC is part of the ASP.NET framework. Developing an ASP.NET MVC application is an alternative to developing ASP.NET Web Forms pages; it does not replace the Web Forms model. 2 QuicSolvTechnologiesPvt.Ltd.

- 4. MODEL-VIEW-CONTROLLER Controller: - The controller is like a traffic cop. Whenever user requests any resource it first goes to the controller. Controller than interact with both the Model and View. Model: - The model is responsible for the data for the application and also it creates data for the view. It handles data processing and database works part. View: - It is a presentation layer i.e. it shows the data to the users. 4 QuicSolvTechnologiesPvt.Ltd.
- 5. BASIC CONVENTIONS IN ASP.NET MVC There is single controller directory which holds your controller classes. Each controller’s name ends with “Controller” e.g. : HomeController Views that controller use live in subdirectory of the Views main directory. Directory for above HomeController will be “Views/Home” All reusable UI elements live in similar structure above but in a “Shared” directory on Root. 5 QuicSolvTechnologiesPvt.Ltd.
- 6. BASIC CONVENTIONS IN ASP.NET MVC Controller contains all Controller classes. Models contains all Models classes. Views contains associated views. Content contains all CSS / Images / other libraries Script contains default scripts loaded MVC 6 QuicSolvTechnologiesPvt.Ltd.

ASP.NET WEB FORMS VS ASP.NET MVC ASP.NET WeB Form Does well with Abstraction Not fully Testable Not much HTML Expertise required Less maintainable Supported by heaps of third party Server side controls and tools. ASP.NET MVC Works with SoC principle Best for TDD HTML knowledge is required Highly maintainable Supported by various Third party JavaScript controls

- 9. WHY VIEW ENGINES Syntax Skill set/background Productivity Testability View engines that don’t depend on the System.Web.UI.Page are easier to test than the default ASP.NET MVC view engine, which uses Page for a base class of its view implementation. Division of labor If you have designers working on the views, or just want minimal logic in your views, you should choose a view engine that easily mixes with Html.
- 10. Step 1 ASP.NET MVC REQUEST FLOW Incoming request directed to Controller Request Controller
- 11. Step 2 ASP.NET MVC REQUEST FLOW Controller processes request and forms a data Model Request Controller Model
- 12. ASP.NET MVC REQUEST FLOW Step 3 12 QuicSolvTechnologiesPvt.Ltd. Model is passed to View Request Controller Model View
- 13. ASP.NET MVC REQUEST FLOW Step 4 13 QuicSolvTechnologiesPvt.Ltd. View transforms Model into appropriate output format Request Controller View Response

- 15. WHY MVC? It makes it easier to manage complexity by dividing an application into the model, the view, and the controller. It does not use view state or server-based forms. This makes the MVC framework ideal for developers who want full control over the behavior of an application. It uses a Front Controller pattern that processes Web application requests through a single controller. This enables you to design an application that supports a rich routing infrastructure. For more information, see Front Controller. It provides better support for test-driven development (TDD). It works well for Web applications that are supported by large teams of developers and for Web designers who need a high degree of control over the application behavior. 15 QuicSolvTechnologiesPvt.Ltd.
