So the ESB Toolkit is no longer going to be release through codeplex. So where do you register bugs and discuss issues? We have created a couple of new sites for this
You can register bugs on the Connect site at https://connect.microsoft.com/site/sitehome.aspx?SiteID=886&wa=wsignin1.0
There is also a new dedicate forum available at http://social.msdn.microsoft.com/Forums/en-US/biztalkesb/threads these are great for posting issues since this is a monitored forum.
Cheers and keep on BizTalking…
