John and I are finalizing the requirements for the next version of the Developer Book Club site and starting to layout the base using Visual Studio 2005 Beta 2. Thus far, I love the experience. The tools suite is amazing and ObjectDataSource is going to change the way we create UIs and business logic. In my demos for Visual Studio DevCon, I extended the base to support a custom object library to bind to the UI instead of DataSets. The IDE makes it so much easier and definitely better APIs for creating application.
What applications are you writing in 2.0 with Visual Studio?
