I am so glad to see the updates to the native adapters in BizTalk 2006. Scott Woodgate posted a document on the changes here. (you might need to join the BizTalkServerStuff group if this link doesn’t work) I was lucky enough to spend some time with the adapter framework over the past few months, and the behavior of the native ones with 2004 left me scratching my head a few times. Anyhow, I really like the Adapter Framework despite not liking the examples built on it that are included with BizTalk. I’ve also been surprised that the community hasn’t strucken out and developed a bit more. There’s the potential for great extensibility, and it’s not too complicated once one takes a couple weeks to get oriented. The SDK sample adapter with 2004 is way overbuilt in my opinion. Plus it uses the SystemMessageContext class which is on the list of unsupported classes. I honestly had enough with the SDK samples once I found that guy being used, so I don’t know if there are any more or not. Anyhow, kudos to the BTS team for spending some time on these! I think they’ll make a bigger splash than most people anticipate….
