.NET Framework 3.5 builds incrementally on the new features added in .NET Framework 3.0. For example, feature sets in Windows Workflow Foundation (WF), Windows Communication Foundation (WCF), Windows Presentation Foundation (WPF) and Windows CardSpace. In addition, .NET Framework 3.5 contains a number of new features in several technology areas which have been added as new assemblies to avoid breaking changes. They include the following:
- Deep integration of Language Integrated Query (LINQ) and data awareness. This new feature will let you write code written in LINQ-enabled languages to filter, enumerate, and create projections of several types of SQL data, collections, XML, and DataSets by using the same syntax.
- ASP.NET AJAX lets you create more efficient, more interactive, and highly-personalized Web experiences that work across all the most popular browsers.
- New Web protocol support for building WCF services including AJAX, JSON, REST, POX, RSS, ATOM, and several new WS-* standards.
- Full tooling support in Visual Studio 2008 for WF, WCF, and WPF, including the new workflow-enabled services technology.
- New classes in .NET Framework 3.5 base class library (BCL) that address many common customer requests.
IMPORTANT:
* If you have installed earlier pre-release versions of .NET Framework 3.5, then you must uninstall them prior to running this installation by using Add or Remove Programs.
Microsoft .NET Framework 3.5 包含许多与 .NET Framework 2.0 和 .NET Framework 3.0 都可兼容的新功能。.NET Framework 3.5 包括若干针对 .NET Framework 2.0 和 .NET Framework 3.0 的修补程序。

* 与语言集成查询 (LINQ) 和数据感知紧密集成。利用这一新功能,您将能够通过使用相同的语法编写用启用 LINQ 的语言编写的代码,以便筛选、枚举和创建多种类型的 SQL 数据、集合、XML 和数据集的投影。
* 利用 ASP.NET AJAX 可以创建更有效、更具交互性并且高度个性化的 Web 体验,这些 Web 体验可以跨所有最流行的浏览器工作。
* 新的用于生成 WCF 服务的 Web 协议支持包括 AJAX、JSON、REST、POX、RSS、ATOM 和若干新的 WS-* 标准。
* 针对 WF、WCF 和 WPF 的完整工具支持,其中包括新的启用工作流的服务技术。
* .NET Framework 3.5 基类库 (BCL) 中的新类解决了最常见的客户请求。
重要事项:
* 如果安装了 .NET Framework 3.5 的早期版本(例如,测试版),则您必须卸载这些早期版本。
