About this task

This activity creates a WorkflowQueue using the WorkflowQueuingService.

Procedure

  1. From a subprocess, drag and drop a Create Message Queue activity.
  2. In the Queue Name field, provide a name for the message queue. This value can be configured using a literal value, expression, or bind.
    Note: The following restrictions apply:
    • The message queue name cannot be null or empty, and you cannot use workflow instance ID, task instance ID, or task step instance ID as a queue name, because doing so causes the activities to fault at run time.
    • Empty GUIDs are not allowed.
    • Leading and trailing spaces are trimmed in the queue name; otherwise, the queue name is invalid.
    • If the queue name is not a reserved value but the queue already exists, no fault occurs.
  3. Click Save.
