Validate available operations on workflow service RRS feed

  • Question

  • I'd like to check if i can invoke an operation on workflow service so i could disable action buttons on my UI. Is it possible?

    If I invoke operation which isn't right at that moment I get exception:

    "Operation cannot be performed at this time. Please ensure that the operations are performed in the correct order and that the binding in use provides ordered delivery guarantees."

    And i would like to avoid theses kind of messages by validating before invoking.

  • It seems like you have to try the service in order to see if it's valid at the time, so polling the service and trapping the exception might be the way to go, depending on your application.
