ExternalDataExchangeService Class

Definition

Namespace:

System.Workflow.Activities

Assembly:

System.Workflow.Activities.dll

Caution

The System.Workflow.* types are deprecated. Instead, please use the new types from System.Activities.*

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.

Note

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