Where did these all come from?

If you look closely at the ServiceController members listed in the previous figure, you will notice a few members that aren't strictly properties, methods, or events. PowerShell has a mechanism called the Extended Type System that allows PowerShell to add members to classes or to individual objects. In the case of the SystemController objects, PowerShell adds a Name alias for the ServiceName property and a RequiredServices alias for the built-in ServicesDependedOn property.

Tip

Your turn!

Use Get-Member with Dir and Get-Process and see what members PowerShell has added. Look these classes up on MSDN and verify that those properties aren't delivered as part of the .NET framework.
