WF 3.0/3.5 has effectively been taken out back and shot, and replaced with alot sexier version. First look makes it look far easier to use and extend, and can be skinned with WPF 🙂
VS2010 is being converted to a WPF based app (like the Expression tools), and will be taking advantage of a new extensibility model being included in .Net 4.0.
I can’t wait to get hold of the CTPs! 😀
