I'm kind of embarassed to write this but last week was the first time I'd installed a build of Whidbey (the next version of the .NET Framework) in about 6 months. I used to download builds on a daily basis at the beginning of the year when I was a tester working on XQuery but fell off once I became a PM. Given that certain bits were in flux I decided to wait until things were stable before installing Whidbey on my machine and writing a number of sample/test applications.
Over the next couple of weeks I'll be driving refining some of the stuff that we've designing for the next version of System.Xml and will most likely be blogging about various design issues we've had to contend with as well as perhaps giving a sneak preview of some of our end user documentation which will include answers to questions raised by some of the stuff that was shown at PDC such as whether there is any truth to the claims that XmlDocument is dead.
