Crazy ASP. NET Series-First: What is ASP.

Recently want to learn the net, so in the online shop to see a book called the ASP, the wife asked in the next sentence: "This is not DSP (digital signal processing, university reading of electronics, so this relatively ripe), is ASP ah, what is ASP ah?" ”。 I thought for a few days, did not think of this abbreviation is what meaning, for a year of. NET children, incredibly even this do not know, work really did not in the following good reading AH. Some children like to learn in practice, some children like reading, I prefer reading + practice, preferably have a small project can do, the existing conditions can only read +demo, see small Edith every day have summed up, the heart also itch, to him study. More gossip, get to the point: what is ASP.

1.ASP. The origin of net

Ten years ago Microsoft released the. NET Framework (Microsoft. NET Framework) is a new managed-code programming model for Windows, a place that doesn't understand, and later looks at An ASP. NET was developed on this platform to build Web site tools. ASP (Active Server Pages) is an abbreviation for a dynamic server page that is currently published to version 4.5. As for why Microsoft to publish ASP, initially can literally understand, 1. Dynamic page, the previous site is static HTML page; 2. Server page, you can operate the database on the server side, display the data in the front, access the file system and so on.

2.asp.net WEB VS ASP. NET MVC

Before I saw that MVC thought it was a very powerful thing (something you might not be familiar with would think it was great)

Baidu Encyclopedia: The full name of MVC is the Model View controller, which is the abbreviation of models-View-controller, a software design paradigm that organizes code with a method of business logic, data, and interface display separation. Aggregating business logic into a single component, without the need to rewrite business logic while improving and personalizing the interface and user interaction

The approximate meaning is a framework, divided into three layers, the three layers are isolated (after looking at the old a write MVC write details of what MVC is)

3.ASP. NET's 7 main features:

(1) ASP integration with the. NET Framework

This means that ASP. NET will use the various classes provided by the. NET Framework, regardless of the type of application (such as stand-alone window applications, window services, command-line tools) created by ASP.

(2) ASP. NET is compiled and executed, not interpreted.

First, the. NET program compiles into an intermediate-language Il (essentially, all. NET languages (including C#,VB, etc.) are compiled into almost the same intermediate language), and this step is that. NET can do the key to language-independent.

When the page is first requested, the first compilation is compiled automatically, or it can be compiled in advance (precompiled), and the compiled intermediate code IL is called the assembly. When the page executes, the intermediate code compiles the cost machine machine code (JIT, instant compilation)

Why compile two times: give developers the greatest convenience and the best portability.
