Well, WSE 2.0 RTMed today, you can download it here. Just my luck that the class I teach tonight is the first in-depth WSE class, but all the demos and examples use WSE 2.0 Technology Preview! Drat.
Despite the setback for my students, it's good to see WSE 2.0 get out the door. I've yet to have had any chance to play with any bits more mature than WSE 2.0 TP, so I hope there is not too many breaking changes in the API between the TP and RTM.
