The WorkflowOutput operator is used inside nested workflows to specify the sequence of notifications providing the result of the nested function. In each workflow there can only be at most one WorkflowOutput node. How this result sequence is converted into the sequence of notifications of the outer nesting node is dependent on the exact operator in which the output is nested.

If no WorkflowOutput is specified, the result sequence of any nested workflow (including the top-level workflow) will be of type Unit and will not emit any notifications except for successful termination if all inner sequences terminate successfully, or exceptional termination if any of the inner sequences raises an error.

Note

If the sequence connected to WorkflowOutput terminates successfully, all other nested operators will be immediately cancelled. This is also true for the top-level workflow, in which case the entire program execution is terminated.
