| The Best from DevelopMentor | MORE | - Windows Workflow Foundation 4 and persistence
The persistence class out of the box is called SqlWorkflowInstanceStore and as the name suggests it saves workflow data in either SQL Server 2005 or 2008. We can attach it to either a WorkflowApplication or a WorkflowServiceHost and persist workflows when we want. This can be used to run only short lived workflows and doesn’t support persistence. var instanceStore = new SqlWorkflowInstanceStore(connStr); WorkflowApplication app = new WorkflowApplication(workflow); app.InstanceStore = instanceStore; app.Run(); Okay its a little more involved then that.

In Windows Workflow Foundation 4 it’s easy to create a workflow and expose it as a WCF service. But one thing is that it exposes a XAMLX endpoint to each client can see the service actually implemented as a workflow service instead of a regular service.

Search Searching through workflows is another big one. With small workflows it is quite easy to see where a variable is used but when workflows get bigger this becomes an increasingly hard problem.
