Migration Activity in WF

This topic applies to Windows Workflow Foundation 4 (WF4).

.NET Framework version 4 provides the Interop activity for executing activities that derive from Activity within a workflow that is based on Activity. For more information, see the Migrating Workflows section.

Visual Basic Note:
The Interop activity does not appear in the workflow designer toolbox unless the workflow's project has its Target Framework setting set to .Net Framework 4.
