I would like to mention that there is a great book available about BizTalk 2006. It is called BizTalk 2006 Recipes, published by Apress and written by Mark Beckner, Ben Goeltz, Brandon Gross, Brennan O`Reilly, Stephen Roger, Mark Smith and Alexander West. (ISBN 1-59059-711-7)
In the book you will find a comprehensive guidance on working through complex deployment challenges, including tested, reusable code snippets for use in production, enabling faster deployment and minimal post-implementation engineering support.
The book is intended for starting BizTalkers as well as the seasoned BizTalk professional, but in my opinion it might be useful to have already a little introduction to the BizTalk development environment before starting with this book.
I already did a quick read in the book during my BizTalk 70-235 study, the book gives a detailed step by step overview of solutions (with lots of images) on how to work with BizTalk. The authors really did a good job to provide you with solutions that work, but best of all that works well.
In the next month(s) I will read this book and try to run all the provided solutions. Of course I will post feedback about this book on this blog.
