Hello there!
For any of you who may be using the BizTalk 2013 RTM, and the ESB Toolkit 2.2, there is an error you will encounter selecting an itinerary using either the BRI or ITINERARY-STATIC resolvers in your receive pipeline. The following article describes the problem and the workaround. It boils down to the esb.config file not being updated for the new Unity container, so the XML structure is now incorrect. This article provides a nice download of the modified configuration fileand I’ve verified it works!
