  Microsoft .NET RIA Services March '09 Preview

  (4.1 MB): Microsoft .NET RIA Services simplifies the traditional n-tier application pattern by bringing together the ASP.NET and Silverlight platforms. RIA Services provides a pattern to write application logic that runs on the mid-tier and controls access to data for queries, changes and custom operations. It also provides end-to-end support for common tasks such as data validation, authentication and roles by integrating with Silverlight components on the client and ASP.NET on the mid-tier.

  Microsoft Silverlight 3 SDK Beta 1

  (9.6 MB): The Microsoft® Silverlight™ 3 SDK contains online documentation, online samples, libraries and tools for developing Silverlight 3 applications. Usage of the SDK is subject to the SDK License (included in the package).

  Microsoft Silverlight 3 Tools Beta 1 for Visual Studio 2008 SP1

  (31.3 MB): This package is an add-on for Visual Studio 2008 SP1 to provide tooling for Microsoft Silverlight 3. It can be installed on top of either Visual Studio 2008 SP1 or Visual Web Developer 2008 Express with SP1, and it provides a Silverlight project system for developing Silverlight applications using C# or Visual Basic.

  Silverlight 3 将成为今年会议上的重点内容，我们很期待微软会给我们带来些什么。稍微一等，keynote演讲将在3月18日 9:00 A.M. PDT开始进行。
