6.13. Summary

WF4 has many excellent features and is much easier to use in VS2010. The move to integrate WCF and WF more closely is sensible given the overlap of the two technologies. The introduction of the flowchart model and new activity types will make it easier to model many scenarios. It is somewhat disappointing that Microsoft has chosen to drop support for state workflow, which could leave some users with a lot of work to upgrade their code bases. In conclusion, I suspect that despite its many excellent features, WF will remain a secondary technology due to its learning curve.
