Remarks
This method is called when Visual Studio needs to evaluate which toolbox items should be enabled. The default implementation searches the service provider for the IVsToolboxUser interface and delegates. If the IVsToolboxUser interface cannot be found, this will search the service provider for IToolboxService and call IsSupported.
