ExternalDataExchangeService Class

 
Note: This API is now obsolete.

Represents a service that must be added to the workflow run-time engine for local services communications to be enabled. Local service implementations are required to be added to the ExternalDataExchangeService for these services to be properly initialized and registered.

Namespace:   System.Workflow.Activities
Assembly:  System.Workflow.Activities (in System.Workflow.Activities.dll)

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

A local service implementation is a class that implements an interface that is marked with ExternalDataExchangeAttribute. Local services added in this way are used by CallExternalMethodActivity and HandleExternalEventActivity.
