Anyone know of a class that implements ISelectionService and/or IComponentChangeService

In creating my own custom ParentControlDesigner, my public override void Initialize( IComponent component ) processes these interfaces for working with the designer window

  ISelectionService service = (ISelectionService)this.GetService( typeof( ISelectionService ) );
  if ( service != null )
    service.Selection开发者_Go百科Changed += new EventHandler( this.OnSelectionChanged );

  IComponentChangeService service2 = (IComponentChangeService)this.GetService( typeof( IComponentChangeService ) );
  if ( service2 != null )
    service2.ComponentChanged += new ComponentChangedEventHandler( this.OnComponentChanged );

I was wondering if someone knew any classes that implemented the ISelectionService and IComponentChangeService. I want to see how they are built and possibly referenced. In googling ISelectionService, I got a number of linked to either a definition or the Initialization implementation but no links to a class that actually implements ISelectionService.

Here are two good articles on how to host the Visual Studio forms designer in your own application. These may give you the information you need.
