Microsoft .NET 下一代互联网开发平台 新观念（Vision） 软件作为服务“Software As A Service” 标志 Longhorn, Office 12, SQL Server 2k5,Visual Studio2005 … etc 体系结构 XML Web Services Microsoft .NET对Web Services的支持 Microsoft是Web Services标准的重要贡献者以及领跑者 Microsoft .NET 为Web Services定身量做 高效的Web Services开发 What Is .NET? .NET is a technology evolution built from the ground up for the Web. --It is not a bolt-on solution. It’s a new framework that can provide seamless integration of multiple applications and devices. It can be used to take advantage of the abundant computing and communications resources provided on the Internet to enable smart, service-aware systems and richer user experiences. .NET is based on standards and a unified programming model. Web standards are open and non-proprietary, they are built to be first-class constructs and they drive interoperability and integration of new existing systems. .NET is multi-language because it works in the language of your choice. XML Web services enable you to build and operate Web services that deliver software as a service. XML Web services are today’s best-of-breed business integration since they allow customer centricity in your business applications. Consistent programming model with the highest productivity tools. Visual Studio .NET is the next generation of the Microsoft Integrated Development Environment. Everyone who has been using Microsoft development tools will feel right at home with Visual Studio .NET. Lower total cost of ownership with reusable self-describing applications, no registry, robustness and security and simplified deployment. Note: There is a .NET runtime for Windows 98 and up. The development environment is Windows 2000 and up.

Web Services 开发拾遗 同步 VS 异步 启用状态管理 参与使用事务 利用缓存提高Web Services的性能

异步 VS 同步 同步 ＆ 异步的概念 同步 VS 异步 异步方法 服务端异步 客户端异步

启用状态管理 Application VS Session 启用 EnableSession 访问Application状态 [ WebMethod(EnableSession=true) ] public int PerSessionServiceUsage(){}

参与使用事务 基于声名性的事务参与 使用TransactionOption属性 注意：只能作为新事务的根参与事务 [ WebMethod(TransactionOption=TransactionOption.RequiresNew)] public int DeleteAuthor(string lastName){}

利用缓存提高Web Services的性能 使用CacheDuration选项
