ManualWorkflowSchedulerService Class


The .NET API Reference documentation has a new home. Visit the .NET API Browser on to see the new experience.

Note: This API is now obsolete.

Provides a threading service that allows the host application creating a workflow instance to donate the Thread on which the workflow instance is run. Using this threading service, host applications can run a workflow instance on a single Thread in synchronous mode (although if the workflow contains a delay activity, the work is postponed until after the delay activity is executed on a separate thread spawned by System.Threading.Timer).This mode blocks the execution of the host application until the workflow instance becomes idle. Subsequently, the workflow instance can only be executed using the RunWorkflow method of this service.

public class ManualWorkflowSchedulerService : WorkflowSchedulerService


Initializes a new instance of the ManualWorkflowSchedulerService class.


Initializes a new instance of the ManualWorkflowSchedulerService class.


Initializes a new instance of the ManualWorkflowSchedulerService class.


Gets the WorkflowRuntime for this service.(Inherited from WorkflowRuntimeService.)


Gets the state of the WorkflowRuntimeService.(Inherited from WorkflowRuntimeService.)


Cancels the specified existing workflow instance work item.(Overrides WorkflowSchedulerService.Cancel(Guid).)


Determines whether the specified object is equal to the current object.(Inherited from Object.)


Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)


Serves as the default hash function. (Inherited from Object.)


Gets the Type of the current instance.(Inherited from Object.)


Creates a shallow copy of the current Object.(Inherited from Object.)


Overloaded from WorkflowRuntimeService.OnStarted. This method is called whenever WorkflowRuntime.StartRuntime is called and is used by the ManualWorkflowSchedulerService to do work that is needed when the WorkflowRuntime starts.(Overrides WorkflowRuntimeService.OnStarted().)


When overridden in a derived class, represents the method that will be called when the workflow runtime engine raises the WorkflowRuntime.Stopped event.(Inherited from WorkflowRuntimeService.)

System_CAPS_protmethodRaiseServicesExceptionNotHandledEvent(Exception, Guid)

Runs the specified workflow instance.

System_CAPS_protmethodSchedule(WaitCallback, Guid)

Adds a workflow instance to the pending work items queue using the specified workflow instance using the specified multicast delegate. (Overrides WorkflowSchedulerService.Schedule(WaitCallback, Guid).)

System_CAPS_protmethodSchedule(WaitCallback, Guid, DateTime, Guid)

Adds the specified workflow instance to the pending work item queue using the specified multicast delegate, DateTime and GUIDs. (Overrides WorkflowSchedulerService.Schedule(WaitCallback, Guid, DateTime, Guid).)


When overridden in a derived class, starts the service and changes the State to Starting.(Inherited from WorkflowRuntimeService.)


Overloaded from WorkflowRuntimeService.Stop. The ManualWorkflowSchedulerService uses this method to do work that is needed when the WorkflowRuntime stops.(Overrides WorkflowRuntimeService.Stop().)


Returns a string that represents the current object.(Inherited from Object.)


This material discusses types and namespaces that are obsolete. For more information, see Deprecated Types in Windows Workflow Foundation 4.5.

ManualWorkflowSchedulerService does not automatically run a workflow instance that is in the queue. The host must call RunWorkflow to run a specified workflow.
