System.WorkflowModel 4.0.10924.1: Throwing exception: System.InvalidOperationException: A Location cannot be generated from an Expression of type Call.


This exception is thrown by Workflow Model when the sender sends the message with invalid action. That culd mean that the action is not known by the receiver. For example ReceiveAction is bount to operation IMyService.Operation1, butservice sends the message with action=Ooperation1
