Description

The OTX OTX ExternalServiceProvider Extension extension introduces a data type named Service. The new Service type is a handle to a running service. If the ExecuteService action is called the service handle is given back in a variable. When the ExecuteService is used with executeAsync attribute set to true, the only way to be notified that the service has finished is to use the ServiceExecutionFinishedEventSource term.
