Have you asked yourself "What do I want from ASP.NET?", "How web development would look like in 2, 4, 6 years from now?", "Is the Silverlight silver bullet in web development?"... Well who knows... but there is CTP of what Microsoft is working on in ASP.NET area and it is called Microsoft ASP.NET Futures (May 2007) Release.
ASP.NET Futures includes a number of new, innovative solutions that help developers become more productive and enables them to create better user experiences for their customers. Features include:
ASP.NET AJAX Futures
The new release includes support for managing browser history (Back button support), selecting elements by CSS selectors or classes, and information on accessing “Astoria” Web data services.
Silverlight Controls for ASP.NET
Dynamic Data Controls for ASP.NET
Dynamic data controls are a set of ASP.NET server controls that obtain database schema information at run time, provide default display formats according to common user expectations, and enable you to easily customize those formats. Watch a video showing how to build a task list application using the Dynamic Data Controls from the ASP.NET Futures Release.

Dynamic Languages Support in ASP.NET
In ths release, support for dynamic languages in ASP.NET expands on the earlier support for IronPython for ASP.NET. Support for dynamic languages in ASP.NET is built on the Dynamic Language Runtime (DLR), a new platform currently under development at Microsoft. The DLR simplifies hosting dynamic languages on the Common Language Runtime.
Two dynamic languages are now hosted on the DLR: IronPython and Managed JScript.
