NoteNote

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

Caution noteCaution

Due to limitations in the interface types that the Interop activity can support, HandleExternalEventActivity and CallExternalMethodActivity cannot be used directly, but derivative activities created using the Workflow Communication Activity tool (WCA.exe) can be used. See Windows Workflow Foundation Tools for details.
