这些新闻，有几位朋友已经陆续发布过了。我这里总结一下：
DLR发布，DLR作为CLR的一个扩展，可以让大量动态语言很容易的在.NET实现。DLR
以Microsoft.Scripting.dll程序集为核心，对于特定语言另外扩展一个程序集（如：IronPython的扩展程序集为：Microsoft.Scripting.Vestigial.dll）
SilverLight1.1Alpha最大的特性是支持CLR语言，包括我喜欢的IronPython。这个版本的SilverLight也使用DLR技术来支持脚本语言的执行。
IronPython发布了2.0 Alpha，同样是基于DLR之上实现。
同时，微软也同步发布了Microsoft ASP.NET Futures May 2007，这个东西更是一个Future的好东西，包括了：ASP.NET AJAX Futures，Silverlight Controls for ASP.NET，Dynamic Data Controls for ASP.NET，ASP.NET Application Services，Dynamic Languages Support in ASP.NET
Jasper : .Net Components for Quick and Clean Data Access for Rapid Development
这样使用Jasper就可以作为IronPython的ORM来实现IronPython On Rail了
引用alex@base4.net的话说：
=======================
Jasper is a sort of Dynamic ORM a-la Ruby on Rails, it takes advantage of dynamic language capabilities of .NET, the rails idea of convention over configuration and leverages Microsoft Entity Framework under the hood.
In other words it is cool....
Read more about it here on Carl's blog. And if you want to get started all you need is:
1) Microsoft Visual Studio Codename “Orcas” Beta 1. Install from here.
2) Iron Python 1.1. Install from here.
3) Microsoft SQL Server 2005. The Microsoft SQL Server 2005 SP 2 Express Edition can be found here.
4) “Jasper. Install from here.
How cool is it that Microsoft is really innovating and growing the capabilities of .NET?
