Examples
The following code example demonstrates how to create a new instance of the PolicyActivity class and set its properties. This code example is part of the RuleActionTrackingEventSample SDK sample from the SimplePolicyWorkflow.designer.cs file. For more information, see RuleActionTrackingEvent Sample.
// A workflow is always run asychronously; the main thread waits on this event so the program
// doesn't exit before the workflow completes
workflowRuntime.AddService(new SqlWorkflowPersistenceService("Initial Catalog=SqlPersistenceService;Data Source=localhost;Integrated Security=SSPI;"));
' A workflow is always run asychronously the main thread waits on Me event so the program
' doesn't exit before the workflow completes
WorkflowRuntime.AddService(New SqlWorkflowPersistenceService("Initial Catalog=SqlPersistenceServiceData Source=localhostIntegrated Security=SSPI"))
