Task Host Container
Applies to: 
SQL Server
SSIS Integration Runtime in Azure Data Factory
The task host container encapsulates a single task. In SSIS Designer, the task host is not configured separately; instead, it is configured when you set the properties of the task it encapsulates. For more information about the tasks that the task host containers encapsulate, see Integration Services Tasks.
This container extends the use of variables and event handlers to the task level. For more information, see Integration Services (SSIS) Event Handlers and Integration Services (SSIS) Variables.
Configuration of the Task Host
You can set properties in the Properties window of SQL Server Data Tools (SSDT) or programmatically.
For information about setting these properties in SQL Server Data Tools (SSDT), see Set the Properties of a Task or Container.
For information about programmatically setting these properties, see TaskHost.
