WorkflowServiceHost class
Namespace: System. ServiceModel
Assembly: System. WorkflowServices. dll
We usually use IIS or WAS (Windows Activation Services) to expose the service. Here we use the WorkflowServiceHost class to configure and expose the workflow as a service to the client application. Of course, IIS and WAS can interact with the WorkflowServiceHost instance object.
We can use the WorkflowServiceHost instance object to load the workflow service, configure endpoints, Set application security, enable listening, and process sent requests.
