Windows Server AppFabric provides an API for implementing custom Instance Store, Query, and Control providers.
In the first recipe of this chapter, we have seen that Windows Server AppFabric provides a default SqlWorkflowInstanceStoreProvider which provides access to .NET Framework's SqlWorkflowInstanceStore. As Windows Sever AppFabric uses provider models we can implement a custom Instance Store provider.
