UPDATE: I have since moved these articles to my own blog and they can be found here.
I just posted my third article in a series about BizTalk Server 2006 R2 integration with Windows Communication Foundation. The topic of this piece is Transactions and how to create and consume WCF services using the WS-AtomicTransaction specification. Transactions are sometimes a tricky thing to grasp, so I included a brief (but hopefully understandable) explanation of the key WCF transaction concepts. Then I showed how to use BizTalk to flow transactions to services. A few gotchas arose, which simply demonstrates that while BizTalk Server 2006 R2 is a move forward, it’s still relatively immature with regards to .NET 3.0+ integration.
As always, if you have any questions or comments on the article, let me know.
