Orchestration pattern videos
The second part of the Orchestration pattern seminary that Charles Young did for us at the BizTalk User Group Sweden at our december meeting is now live on channel9 and can be viewed here. The first part, which we announced here, is available for viewing on channel9 here. Posted with the help of the Microsoft Swedish MSDN Team. Thanks to all involved for making this happen - with a little luck we should be able to do it again (that is, record our meetings and get them posted to channel9). They seem to be popular.
Although Charles talks about patterns, and useful such, you might be looking for even more. I recommend the BizTalk Server Orchestration Pattern Wizard available on codeplex. And also check out the download that on top of the sourcecode and other things contains videos explaining the included patterns by Jon Flanders.
