I am doing quite a bit with the WSE 2.0 Tech Preview lately, specifically around WS-Policy and WS-Security Kerberos Binding. I am also giving a lot of presentations surrounding these specs (hopefully I will get the time to post some code samples soon).
Giving these presentations, people frequently ask “when was this spec released”? Early Adopter points to a WSA Timeline.
Gonna make this one into a PowerPoint slide today.
