Fundamentals of MVC

Chapter 1 Fundamentals of MVC

Microsoft's Web Development Platforms

Understanding the past can be a big help in appreciating the present.

1.ASP

asked for features such as improved code reuse,better separation of concerns,and easier application of object-oriented programming principles.

2. ASP.NET Web Forms

an abstraction from the underlying HTML,Js,and Css

3.ASP.NET MVC

The Architecture encourages strict isolation between the individual parts of application.

Benefits:

Development:Isolated componensts;

Testability;

Maintenance.

The MVC Architecture

The model repesents core business logic and data.

The view is responsible for transforming a model or models into a visual representation.

The Controller is the coordinator between the view and the model.

Async Controllers:just like node.js?

Display modes:different devices.

Bundling and minification:script and css combining and minification.

Web API:supply data to the different platform.

Convention over Config

Action Results

Content() :string

File():file e.g.,a pdf

HttpNotFound() :404

Javascript():js

Json()

PartialView() :without layout

Redirect():302

RedirectPermanent

View()

Action Filters

create own filters by extending the ActionFilterAttribute

Views

Code nuggets

rendered inline. like this: @Html.ActionLink("Login", "Login")

Code blocks

like this:@{}

Layouts

layouts like this:

content like this:

Partial Views

Displaying Data

It is the controller’s job to be the “traffic cop,” coordinating various parts of the system to execute the application’s logic.

ViewData ,

TempData,

ViewBag(dynamic)

View model(Strongly typed).

HTML and URL Helpers

HtmlHelper :helps you generate HTML markup

UrlHelper :helps you generate URLs.

Models

Putting It All Together

As a recap, every ASP.NET MVC request requires at least three things: a route, a controller action, and a view (and, optionally, a model).

The Route

The Summary

ASP.NET MVC leverages the time-tested Model-View-Controller architecture pattern to provide a website development framework that encourages loosely coupled architecture and many other popular object-oriented programming patterns and practices.
