Scott Woodgate, Lead Product Manager for BTS 2004, presented this one. Scott Woodgates blog Started with an overview of SOA first, which was a good idea for developers to understand prior to working with BizTalk Server 2004. Went into a "what is BizTalk Server 2004" talk, explaining why in this case development of stateful objects is not evil. Most of BTS 2004 written in C# - 1.8M lines oc code, largest .NET Framework code-base shipping today. Orchestration compiles to MSIL, deploys as assembley, deployed and versioned in the GAC because the server is a windows service (series of). Key technologies include pub/sub messaging, orchestration, business rules, single sign-on, business activity monitoring, human workflow services, business activity services. Demo showed bulding a schema, promoting fields, mapping and a functoid. They went into the pipeline editor, then BizTalk Editor and an overview of send/receive ports, filters, adapters. Cool part of demo showing Health and Activity Tracking, stepping through an orchestration to follow the path of a message. Then we got to see how the newly released WSE Adapter works with BTS 2004.
