Microsoft conference unveils new upcoming technologies

Microsoft is having PDC (Microsoft Professional Developers Conference) in Los Angeles USA this week and blogs around the internet has started to get very interesting posts regarding Longhorn and Whidbey.
I found extremely interesting post in Longhorn blogs where Ryan Dawson is writing about new upcoming technology: XAML, which stands for XML Application Markup Language which is basically Microsoft implementation of XUL.
From PDC site you can find also PDC blog list and lots of other intresting stuff to read and watch.
