Remarks

The Workbook implements the 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 Workbook.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.
