Note

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

A TimerEventSubscriptionCollection represents the queue of TimerEventSubscription objects associated with a workflow instance and provides methods to manage this queue. Subscriptions are ordered in the queue based on their ExpiresAt values; those with smaller ExpiresAt values are positioned before those with larger ExpiresAt values. You can use the methods provided by this class to manage the collection of active timer event subscriptions exposed by TimerCollectionProperty for each workflow instance. You can use Add or Remove to add or remove subscriptions from the timer queue. Whenever the first element in the timer queue changes, the WorkflowSchedulerService is called to cancel the timer event that was previously at the beginning of the queue and schedule the new timer event.
