I've been delivering a "What's New for Web Developers in Visual Studio 2008 & the Microsoft ASP.NET Futures" session over the last few months to various customers and partners.  All of the features / demos I have shown were based on Visual Studio 2008 Beta 1.  When Beta 2 is released, there will be a few features you most likely have not seen.  One of them is the LinqDataSource control.  Scott Guthrie just published LINQ to SQL (Part 4 - Updating our Database) which (in addition other things) is a walkthrough of the LinqDataSource control.  I will be delivering What's New for Web Developers in Visual Studio 2008 & the Microsoft ASP.NET Futures on Wednesday, July 25th, as part of my team's July Webcasts.  Wednesday's webcast will be the first time I demo the Beta 2 features.
