Exposing Windows Workflow to SOA: Real Life Lessons

In this 90 minute presentation, Paul Sorauer from Code Red Solutions, will demonstrate the practical steps required to expose Windows Workflow to SOA, and discuss the lessons learn from real-world projects.

Service-Orientated-Architecture is becoming increasing more important when designing ‘Enterprise Level' software solutions, and the recent releases of Visual Studio 2008 and .Net 3.5 now provide us with the ability to create Windows Workflows exposed to SOA via WCF endpoints. This ability to offer workflow as a service removes it from a tightly-coupled architecture, with the added benefit of making it much easier to consume from stateless environments such as ASP.NET.

• What Workflow is and when to use it;
• An overview of Sequential vs. State Machine Workflows;
• The basic steps required to expose a State Machine Workflow as a WCF Service;
• Various ‘Gotchas' and lessons learnt the hard way;
• Bugs with Visual Studio's design time support for Workflow Services and their workarounds;
• Custom Activities;
• The Workflow Persistence Service;
• Workflow support for database transactions.
