区别b/w框架2.0和3.0? [英] Difference b/w framework 2.0 and 3.0?

问题描述

.Net2.0和.Net3.0有什么区别
我知道3.0中增加了一些新功能，例如
WPF
WCF
世界自然基金会
可能还会更多.

但是，框架中是否已有任何更改并已更改?

在采访中，有人问我3.0中增加了哪些功能，从而使开发人员的生活变得容易. + WCF + WPF + WF.

.NET Framework 2.0

•针对希望托管.NET运行时实例的本机应用程序的新托管API.
•对x64和IA64硬件平台的完全64位支持.
•对直接内置于.NET CLR的泛型的语言支持. •许多其他和改进的ASP.NET Web控件.
•具有声明性数据绑定的新数据控件.
•ASP.NET的新个性化功能，例如对主题，外观和Web部件的支持.



.NET Framework 3.0

Windows Presentation Foundation(WPF)，以前的代号为Avalon；基于XML和矢量图形的新用户界面子系统和API，它将利用3D计算机图形硬件和Direct3D技术.
Windows Communication Foundation(WCF)，以前的代号为Indigo；一个面向服务的消息传递系统，它允许程序与Web服务在本地或远程进行互操作.
Windows Workflow Foundation(WWF)允许使用工作流构建任务自动化和集成事务.
Windows CardSpace(WCS)，以前的代号为InfoCard；安全地存储个人数字身份并提供用于选择特定交易(例如登录网站)身份的统一界面的软件组件.


2.0 => VS 2005 VB 8.0/C#2.0附带的框架
3.0 =>与2.0 + WCF + WPF + WF相同的框架



2.0和3.0都使用2.0 CLR(公共语言运行时).唯一的区别是在3.0中添加了Windows Communication Foundation，Windows Presentation Foundation和Workflow组件.

You have answered your own question, 3.0 = same framework as 2.0 + WCF + WPF + WF.

.NET Framework 2.0

• A new hosting API for native applications wishing to host an instance of the .NET runtime
• Full 64-bit support for both the x64 and the IA64 hardware platforms.
• Language support for Generics built directly into the .NET CLR.
• Many additional and improved ASP.NET web controls.
• New data controls with declarative data binding.
• New personalization features for ASP.NET, such as support for themes, skins and webparts.



.NET Framework 3.0

• Windows Presentation Foundation (WPF), formerly code-named Avalon; a new user interface subsystem and API based on XML and vector graphics, which will make use of 3D computer graphics hardware and Direct3D technologies.
• Windows Communication Foundation (WCF), formerly code-named Indigo; a service-oriented messaging system which allows programs to interoperate locally or remotely similar to web services.
• Windows Workflow Foundation (WWF) allows for building of task automation and integrated transactions using workflows.
• Windows CardSpace (WCS), formerly code-named InfoCard; a software component which securely stores a person''s digital identities and provides a unified interface for choosing the identity for a particular transaction, such as logging in to a website.


2.0 => framework that shipped with VS 2005 VB 8.0 / C# 2.0
3.0 => same framework as 2.0 + WCF + WPF + WF



2.0 and 3.0 both use the 2.0 CLR (common language runtime). The only difference is addition of Windows Communication Foundation, Windows Presentation Foundation, and Workflow components in 3.0.
