What is ASP.NET MVC

ASP.NET MVC is an MVC model website application development framework based on ASP.NET officially launched by Microsoft.

The official website is: http://www.asp.net/mvc.

The first version of ASP.NET MVC was the RTM version released on March 17, 2009. Since its launch, it has been welcomed by programmers.

The latest ASP.NET MVC 3.0 was officially released on January 13, 2011.

Use suggestions

1. After downloading, you will get an .msi installation file. Double-click it to install.

2. Different versions of ASP.NET MVC can coexist, which means that on the same machine, some programs can use ASP.NET MVC 1 and some programs can use ASP.NET MVC 2.

3. ASP.NET MVC 2.0 is integrated by default in Visual Studio 2010 and there is no need to download it separately.

MVC divides a web application into three parts: Model View and Controller. The ASP.NET MVC framework provides an MVC-based application that can replace ASP.NET WEB forms.

Advantages of MVC:

1. By dividing the project into model view and controller, complex projects are easier to maintain.

2. Without using view state and server form controls, it is more convenient to control the behavior of the application

3. The application controls program requests through the controller, which can provide rich URL rewriting.

4. Better support for unit testing

5. Perform better in team development mode

Advantages of Web Forms

1. Use event-driven mode to control application requests, supported by a large number of server controls

2. Using the page control mechanism, event processing functions can be added to a single page.

3. Use view state and server-side pages to make it easier to manage page state information.

4. It is more convenient for smaller development teams who want to use server-side controls.

5. It is easier and simpler to develop than the mvc model.

MVC Framework Features

1. Separation of tasks (input logic, business logic and display logic), testability and default test-driven components. All components used by MVC are based on interfaces and can be tested by mock objects. You can use the tests without running the controller in the ASP.NET process. Makes testing faster and simpler.

2. Extensible and simple framework. The mvc framework is designed to make porting and customization easier. You can add your own view engine and url rewriting strategy. Overload action methods, etc. mvc also supports Dependency Injection (DI) and Inversion of Control (IOC)

3. The powerful URL rewriting mechanism makes it easier for you to create understandable and searchable URLs. The url can not contain any file extension, and the url can be rewritten to make it more search engine friendly.

4. You can use existing page tags, user controls, and template pages of asp.net. You can use nested template pages, embed expressions <%=%>, declare server controls, templates, data binding, positioning, etc.

5. Support for existing ASP.NET programs, MVC allows you to use forms authentication and Windows authentication, URL authentication, group management and rules, output, data caching, session, profile, health monitoring, configuration management system, provider architecture characteristics.
