Remarks

Note

This material discusses types and namespaces that are obsolete. For more information, see Deprecated Types in Windows Workflow Foundation 4.5.

The FreeformActivityDesigner allows users to modify how an activity appears on a workflow design surface. When you associate FreeformActivityDesigner with a custom activity class using the Designer attribute, the custom activity's appearance is different from other activities when a user drops the custom activity onto a design surface. Once FreeformActivityDesigner displays an activity on the design surface, users can draw connectors to other activity designers and resize the designer within the parameters defined by the design surface.

Note

Users can only add connectors to the custom activity because the FreeformActivityDesigner is associated with the top-level activity in a workflow.
