WorkflowSchedulerService Class

Note: This API is now obsolete.

Provides a mechanism to implement your own thread pool to execute the workflow and manage in-memory timer registration and events.

Namespace:  System.Workflow.Runtime.Hosting
Assembly:  System.Workflow.Runtime (in System.Workflow.Runtime.dll)

[ObsoleteAttribute("The System.Workflow.* types are deprecated.  Instead, please use the new types from System.Activities.*")]
public abstract class WorkflowSchedulerService : WorkflowRuntimeService

The WorkflowSchedulerService type exposes the following members.

  NameDescription
Protected methodWorkflowSchedulerServiceWhen implemented in a derived class, initializes a new instance of the WorkflowSchedulerService class.
Top

  NameDescription
Protected propertyRuntimeGets the WorkflowRuntime for this service. (Inherited from WorkflowRuntimeService.)
Protected propertyStateGets the state of the WorkflowRuntimeService. (Inherited from WorkflowRuntimeService.)
Top

  NameDescription
Protected methodCancelWhen overridden in a derived class, cancels the scheduled work item with the given timerId.
Public methodEquals(Object)Determines whether the specified object is equal to the current object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as the default hash function. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Protected methodOnStartedWhen overridden in a derived class, represents the method that will be called when the workflow runtime engine raises the WorkflowRuntime.Started event. (Inherited from WorkflowRuntimeService.)
Protected methodOnStoppedWhen 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.)
Protected methodRaiseServicesExceptionNotHandledEventRaises the WorkflowRuntime.ServicesExceptionNotHandled event. (Inherited from WorkflowRuntimeService.)
Protected methodSchedule(WaitCallback, Guid)When overridden in a derived class, this method is called by the runtime to schedule a work item (callback) for a particular instance ID.
Protected methodSchedule(WaitCallback, Guid, DateTime, Guid)When overridden in a derived class, this method is called by the runtime to schedule a work item (callback) for a particular workflow instance to be done at the given time (DateTime).
Protected methodStartWhen overridden in a derived class, starts the service and changes the State to Starting. (Inherited from WorkflowRuntimeService.)
Protected methodStopWhen overridden in a derived class, stops the service and changes the State to Stopping. (Inherited from WorkflowRuntimeService.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

NoteNote

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

WorkflowSchedulerService is that base class for all classes that create threads that run workflow instances on the workflow runtime engine host. These include DefaultWorkflowSchedulerService and ManualWorkflowSchedulerService.

Notes to Inheritors

When you inherit from WorkflowSchedulerService, you must override the following members: Cancel, Schedule and Schedule.
