WorkflowRuntime Class
Represents the configurable execution environment provided by the workflow runtime engine for workflows.
Assembly: System.Workflow.Runtime (in System.Workflow.Runtime.dll)
The following code example demonstrates how you can use WorkflowRuntime functionality from a workflow host. It provides examples of how to use the WorkflowRuntime constructor and the AddService, StartRuntime, and StopRuntime methods. The code also shows the recommended method to create a WorkflowInstance object in a workflow host using the CreateWorkflow method. It also shows how to set event handlers for the WorkflowCompleted, WorkflowIdled, and WorkflowTerminated events.
This code example is part of the Canceling a Workflow SDK Sample from the Program.cs file. For more information, see Canceling a Workflow.
