BufferedReceiveServiceBehavior başka bir WorkflowServiceHost örneğine zaten eklenmiş olduğundan WorkflowServiceHost'a eklenemedi. Her ek WorkflowServiceHost için yeni bir BufferedReceiveServiceBehavior oluşturun.

The BufferedReceiveServiceBehavior instance could not be added to the WorkflowServiceHost because it has already been added to another WorkflowServiceHost instance. Create a new BufferedReceiveServiceBehavior instance for each additional WorkflowServiceHost.
