Microsoft Integration Choices: Biztalk, WCF + WF + Dublin

BizTalk Server is Microsoft's premier Enterprise Integration server. BizTalk combines broad integration capabilities with workflow and long-running transaction management. The tighter integration between WCF and WF, a.k.a WCF Workflow Services in.NET Framework 3.5, provides support for long-running coordination between web services, which overlaps somewhat with BizTalk's capabilities. However, significant development effort is required to replicate in WCF and WF the robust hosting, deployment, scalability and management that come out-of-the-box with BizTalk. In the future, Dublin will provide many of these hosting features for the .NET Framework. Get guidance for making the decision of which technology is right for your project based on the timeline for your project and on the relative strengths of each technology for addressing your specific integration scenarios.
