10. MVC Pipeline: Controllers public interface IController { void Execute( RequestContextrequestContext); } Controller IActionInvoker

11. MVC Pipeline: Action Invoker public interface IActionInvoker { boolInvokeAction( ControllerContextcontrollerContext, string actionName); }

12. MVC Pipeline: Action Invoker Action Invoker Find Action Authorization Filters Request Validation Model Binders Pre-Action Filters Invoke Post-Action Filters Execute Action Result

13. MVC Pipeline: Model Binders public interface IModelBinder { object BindModel( ControllerContextcontrollerContext, ModelBindingContextbindingContext); }

14. MVC Pipeline: Action Filters public interface IActionFilter { void OnActionExecuting( ActionExecutingContextfilterContext); void OnActionExecuted( ActionExecutedContextfilterContext); }

15. MVC Pipeline: Action Results public abstract class ActionResult { public abstract void ExecuteResult( ControllerContext context); } ViewResultBase RedirectResult JsonResult FileResult ViewResult PartialViewResult

16. MVC Pipeline: View Engines public interface IViewEngine { ViewEngineResultFindPartialView( ControllerContextcontrollerContext, string partialViewName, booluseCache); ViewEngineResultFindView( ControllerContextcontrollerContext, string viewName, string masterName, booluseCache); void ReleaseView( ControllerContextcontrollerContext, IView view); }
