I just registered for PDC 2008... This will be my second visit to this great conference after 5 years of waiting for and finally using technologies Microsoft promised at PDC 2003.
Last time they told us about Windows "Longhorn", technologies like Avalon or Indigo. Vista, WPF and WCF became reality, WinFS and ObjectSpaces didn't make it ;-)
It was great fun to see guys like Don Box or Aaron Skonnard in several sessions and discuss with Andres Heilsberg about inheritence mechanisms of C# attributes.
This time we'll hear a lot about services in "the cloud" - it will be fun!
