Persists and disposes a workflow instance asynchronously using the IAsyncResult asynchronous design pattern.
This member is overloaded. For complete information about this member, including syntax, usage, and examples, click a name in the overload list.
|BeginUnload(AsyncCallback, Object)||Persists and disposes a workflow instance asynchronously using the specified callback method and user-provided state.|
|BeginUnload(TimeSpan, AsyncCallback, Object)||Persists and disposes a workflow instance asynchronously using the specified time-out interval, callback method, and user-provided state.|
For more information, seeAsynchronous Programming Overview.
If the workflow instance was previously loaded from persistence, then the same InstanceStore used to load the workflow is used for persistence. If the workflow was created and has not yet been persisted, then an InstanceStore must be configured before calling this method or else an InvalidOperationException is thrown when this method is called.
