If a workflow needs to be terminated at a specific point in time and throw a specific exception, the Terminate Workflow activity can be used.
A few examples could be:
new Exception("Failed Due to xyz") new System.NotSupportedException() new System.NotImplementedException()
TerminateWorkflow will end the Workflow, so catching an exception by using Try-Catch activities may be more desierable. The Reason gets displayed in the Monitor View as the Final Status.
