The workflow can be terminated by the host through a call to the Terminate method, by a TerminateActivity activity, or by the workflow runtime engine when an unhandled exception occurs. The workflow runtime engine raises the WorkflowTerminated event after the workflow instance has been terminated, but before it is invalidated in memory.

For the WorkflowPersisted event, sender will contain the WorkflowRuntime and WorkflowTerminatedEventArgs will contain the WorkflowInstance and information about the reason the instance was terminated in the WorkflowTerminatedEventArgs..::.Exception property.

For more information about handling events, see Consuming Events.

The following code example demonstrates how you can use WorkflowRuntime functionality from a workflow host. The code associates the WorkflowCompleted with an event handler, a method named OnWorkflowCompleted.

This code example is part of the Canceling a Workflow SDK sample from the Program.cs file. For more information, see Canceling a Workflow.

Dim workflowInstance As WorkflowInstance
workflowInstance = workflowRuntime.CreateWorkflow(GetType(SampleWorkflow))
workflowInstance.Start()

Type type = typeof(SampleWorkflow1);
WorkflowInstance workflowInstance = workflowRuntime.CreateWorkflow(type);
workflowInstance.Start();
