ASP.NET 2.0 new features

 
From quickstart:
Simplified Code Behind Model New in 2.0ASP.NET 2.0 introduces an improved runtime for code-behind pages that simplifies the connections between the page and code. In this new code-behind model, the page is declared as a partial class, which enables both the page and code files to be compiled into a single class at runtime. The page code refers to the code-behind file in the CodeFile attribute of the <%@ Page %> directive, specifying the class name in the Inherits attribute. Note that members of the code behind class must be either public or protected (they cannot be private).
C# CodeBehind Code Separation
 
The advantage of the simplified code-behind model over previous versions is that you do not need to maintain separate declarations of server control variables in the code-behind class. Using partial classes (new in 2.0) allows the server control IDs of the ASPX page to be accessed directly in the code-behind file. This greatly simplifies the maintenance of code-behind pages.
这对开发来说确实是一个改进,CodeBehind中去掉server control的声明会使代码"清爽"很多，看起来舒服多了。请看示例:

页面中我们放置一个textbox:
Test.aspx
<%@ page language="C#" CodeFile="Test.aspx.cs" Inherits="Test_aspx" %>
