ASP .NET MVC Mindset
  • MVC stands for Model View Controller.
  • It is a development model used by ASP.NET. 
  • Allows  developing complex applications.
  • ASP.NET MVC gives effective patterns to build
    dynamic websites.
  •  MVC includes features that facilitate rapid,
    test-driven development.
  • Provides an useful way to Organize code, markup,
    and control flow.

5
Controllers
  •  MVC framework maps URLs to classes are referred
    as Controllers
  • Controllers process incoming requests, handle
    user input and interactions, and execute
    appropriate application logic.
  • ControllerBase is the base class for all
    controllers.
  • Controller class inherits from ControllerBase,
    responsible for Locating the appropriate action
    method, getting action method's arguments values
    and Handling errors.

6
Action Methods
  • Responsible to execute user requests and generate
    response to it.
  • Controller defines action methods. Controllers
    can include as many action methods as needed.
  • Action methods on usually have a one-to-one
    mapping with user interactions.
  • When a user enters a URL into the browser,
    controller determines the appropriate action
    method to handle the request. 

7
ASP .NET routing
  • Mapping of web requests to controller actions is
    known as routing.
  • ASP .NET routing engine relies on URL patterns to
    decide which controller action has to handle
    given request.
  • Routing is fully integrated and much powerful
    which helps a lot in Search Engine Optimization.
  • ASP.NET routing enables users to use URLs that do
    not have to map to specific files in a Web site,
    can use URLs that are descriptive of the user's
    action

8
Action result types
  • Action result is a return type of a controller
    method, also called as action method.
  • serves as the base class for Result classes.
  • Action methods return models to views, file
    streams, redirect to other controllers.
  • There are many derived Action Result types you
    can use to return results.

9
Action result types
  • ContentResult Returns a user-defined content
    type.
  • JsonResult Returns a serialized JSON object.
  • EmptyResult Represents a return value that is
    used if the action method must return
    a null result .
  • ViewResult Renders a view as a Web page.
  • FileResult Returns binary output to write to the
    response.
  • RedirectResult Redirects to another action method
    by using its URL.

10
Action selectors and Action Filters
  • Action selectors are attributes that can be
    applied to action methods to invoke in response
    to a request.
  • Action filter is an attribute that you can apply
    to a controller action or an entire controller
    that modifies the way in which the action is
    executed. In ASP.NET MVC there are several
    filters, they are
  • Output Cache This action filter caches the
    output of a controller action for a specified
    amount of time.
  • Handle Error This action filter handles errors
    raised when a controller action executes.
  • Authorize This action filter enables you to
    restrict access to a particular user or role.
