ASP.NET MVC is an open source web framework that provides separation of concerns, testability and extensibility. It uses routing to map URLs to controller actions and dependency injection to create controllers. Controllers execute actions that return view or other results. Filters provide cross-cutting concerns like authorization in a clean, reusable way.

- 1. Inside ASP.NET MVC framework Alexander Beletsky, E-conomic http://beletsky.net @alexbeletsky
- 2. ASP.NET MVC is cool! Why?
- 3. Hey, it's open source See what happens behind the curtain Improve your knowledge Learn from best Super fun
- 4. ASP.NET or ASP.NET MVC ? Have you heard such question?
- 5. ASP.NET is foundation Request processing engine Pushing request thought pipeline Pipeline consists of Modules And ends with Handler
- 6. MvcHanlder - heart of ASP.NET MVC Implements IHttpAsyncHandler, IHttpHandler Creates the ControllerFactory Execute the controller
- 7. Show me the code
- 8. Who is responsible for calling MvcHander?
- 9. Here comes Routing Included in framework 3.5 SP1 Implements recomendations by Jakob Nielsen Save us of URL re-writing module Provides decoupling of URL and page
- 10. Route = URL + Constraints + IRouteHanlder
- 11. Show me the code
- 12. ControllerBuilder & ControllerFactory ControllerBuilder creates ControllerFactory ControllerFactory creates Controller
- 13. Difference in MVC2 and MVC3 MVC2 ControllerBuilder creates factory "directly" MVC3 ControllerBuilder uses SingleServiceResolver SingleServiceResolver depends on IDependencyResolver
- 14. Show me the code
- 15. IDependencyResolver Bridge between ASP.NET MVC and IoC container Very simple interface Introduce extensibility for many entities
- 16. Show me the code
- 17. Controller Execution Get the name of the Action from Route Call ControllerActionInvoker to Invoke action
- 18. Filters Authorization filters – Implements the IAuthorizationFilter attribute. Action filters – Implements the IActionFilter attribute. Result filters – Implements the IResultFilter attribute. Exception filters – Implements the IExceptionFilter attribute.
- 19. Why use filters? DRY code AOP principles in action Better reuse Clean code MVC3 introduces global filters
- 20. Show me the code
- 21. Action Results ViewResult - Represents HTML and markup. EmptyResult - Represents no result. RedirectResult - Represents a redirection to a new URL. JsonResult - Represents a JavaScript Object Notation result that can be used in an AJAX application. JavaScriptResult - Represents a JavaScript script. ContentResult - Represents a text result. FileContentResult - Represents a downloadable file (with the binary content). FilePathResult - Represents a downloadable file (with a path). FileStreamResult - Represents a downloadable file (with a file stream).
- 22. Action Result rendering Extract view name from Route Find view associated with with Route & Action Result Render the view
