In this chapter, we discussed how to enable distributed transaction support for a WCF service. We learned how to choose a binding for a transactional WCF service, how to enable transaction support for the binding, and how to opt in an operation to a transactional WCF service. Now, we can wrap the sequential WCF service calls within one transaction scope and include the distributed transaction into the WCF services. We can also update multiple databases on different computers, all within one single distributed transaction.

In the next chapter, we will learn how to convert an existing SOAP WCF service to a RESTful WCF service.
