    Great! I was already wandering when the January CTP would be available.

    By the way is there a procedure on how to correctly uninstall previous versions of the WinFX Runtime Components?

    Gabriel, for most recent releases, you can simply uninstall them from Add/Remove Components in Windows XP. (On Windows Vista, the WinFX release is tied to the operating system.)

    If you’ve got a really old version of WPF on your machine (i.e. pre-PDC) then there’s a little clean-up that you should do – I’ve got a more detailed article here:

    Thanks for sharing info with us! 😉

    btw, also "Windows Workflow Foundation Beta 2 Hands-on Labs" shows up on MSDN download simultaneously, if someone interested in this.
