I see that Packt Publishing has included a link to a sample chapter in our upcoming book called Microsoft BizTalk 2010: Line of Business Systems Integration. The sample chapter selected is: Integrating with Dynamics 2009. You can read more about the book here and can find the sample chapter download here.
I don’t have a publish date but I expect it to be imminent. The content has been provided to the printer. I will update this post once a publish date is available.
