  • HI SharpLj,

    Activity validation enables activity authors and users to identify and report errors in an activity’s configuration prior to its execution. Windows Workflow Foundation (WF) provides the following three types of activity validation:

    • RequiredArgument and OverloadGroup attributes.
    • Imperative code-based validation.
    • Declarative constraints.

    Further information:

    Configuring Activity Validation

    Please let me know if there is anything that I can do to help.

    Best regards,
