I am the owner for the Technical Learning Center at TechEd for the Connected Systems Track. That is the area where you will be able to hang out with product team members from the WCF, WF, Infocard, and Biztalk Teams. I've lined up a list of chalk talks in our TLC theatres and I'll be posting up a list of those talks soon.
I am giving two chalk talks:
Testing your Custom Channel implementations - This talk will focus on why you need custom channels, and when you do have them, what are the interesting test considerations. At the end, I will demo a basic tool we've built to test custom channels.
Exposing your Custom Channel Implementation to the Configuration System - This talk will focus on things you need to understand to expose any Custom Channel you have so that it is configurable via app.config or web.config. Again, the talk will conclude with a tool we've developed to make it seemingly easy for you.
I hope to see you there!
