Visual Studio Codename Orcas Express Edition beta 1下载

Get an early look at Visual Studio code name "Orcas"
The next version of Visual Studio, Microsoft® Visual Studio® code name “Orcas”, will provide an industry-leading developer experience for Windows Vista, the 2007 Microsoft Office system, and the Web. In addition, it will continue in the Microsoft tradition of development language innovation. To enable early feedback, this page provides links to Community Technology Preview (CTP) and Beta releases of Visual Studio code name “Orcas”, and for technologies that we plan to include in it. As previews of additional technologies become available, we will make them available from this page.

We encourage you to download and try these early releases. Before installing a release, review the prerequisites as some releases may require additional software prior to installation. As with all prerelease software, we encourage you only to install these on a secondary machine, or in a virtual machine, as they are not supported by Microsoft Services support teams. As the goal of these previews is to gather feedback from the developer community, please use Microsoft Connect to report any issues, or to suggest improvements.

Visual Studio Orcas将是第一个允许开发人员针对多个.NET Framework版本开发的Visual Studio版本。这意味着你可以打开或创建一个项目，明确地指定.NET Framework 2.0或者3.0或者3.5版本，Visual Studio会自动地过滤Intellisense，工具箱控件，和添加引用的对话框项诸如此类的东西，只显示指定框架版本里支持的那些特性。然后你可以针对这些不同框架版本进行编译，还能得到每个版本的完全的调试支持。多定向(Multi-Targeting)的很大的好处在于，你可以马上在 Visual Studio Orcas 中使用绝大多数的新特性(譬如，所见即所得(WYSWIYG)设计器和JavaScript 编辑器等)，即使你还在开发或更新老一点版本的项目。
