Workflow TV - Tracking StateMachinesWith WF3, a lot of people wrote apps that enabled/disabled controls based on the current state of a StateMachine and the possible transitions but to do this with WF4 you had to write a fair bit of code.

Workflow TV - How To Build Workflow Services with a Database Repository
Jun 20, 2011 at 11:02 AMYou can store the workflow definitions in Oracle - I'm using Entity Framework 4.1 in my code so you would need a provider that works with Entity Framework.
However, at this time we do not have a Workflow persistence provider for Oracle. You won't need this unless your workflows are long running.
Workflow TV - How To Build Workflow Services with a Database Repository
Jun 17, 2011 at 8:57 AMCan provide a web.config with the VirtualPathProvider? I didn't know that.
I wonder if you could support a VirtualDirectory and then place a web.config file in the VirtualDirectory with the config you need if that would work.
It would be worth a try.
Workflow TV - How To Build Workflow Services with a Database Repository
Jun 16, 2011 at 3:07 PMI don't understand your comment about WorkflowServiceHost being limited. It is no different than a WCF ServiceHost. The WCF Service Host will host one service per host. The WF WorkflowServiceHost will host one workflow per host.
However, you can have multiple services and workflow services in you web application. In fact you don't really deal with the WorkflowServiceHost or ServiceHost classes unless you are self-hosting so they are just another part of the infrastructure most of the time.
The main difference is that the WF service can enforce a messaging protocol with certain operations being available only at certain times.
My guess is that if you can build your solution with WCF services you can also build it with workflow services.
