Recently I gave a presentation on BizTalk Server 2009 at the Carolina Code Camp. The presentation covered the basics of BizTalk as well as the new features of BizTalk Server 2009.
I showed a short demonstration of a sample Purchase Order process. The components used were the Schema Designer, the Mapper, the Orchestration Designer, and the Consume WCF Service Wizard.
PowerPoint slides and demo code are available upon request.
