Name Type Description
serviceType Type

The type of service to add.

A callback object that is used to create the service. This allows a service to be declared as available, but delays the creation of the object until the service is requested.

promote Boolean

true to promote this request to any parent service containers; otherwise, false.


The SchedulerControl implements IServiceProvider and IServiceContainer interfaces. In addition to providing services, it also provides a mechanism for adding and removing services. To obtain a service, call the SchedulerControl.GetService method.

When a service is added, it can be added with instructions to promote it. When a service is promoted, it is added to any parent service container, on up until the top of the service container tree is reached.
