Bing Maps layer file ILayer/object type?

(Cross posted in the ArcGIS Desktop - General forum)
I've been trying to figure out what CoClass the Bing Maps layer file belongs to.
I'm referring to the one offered for use in ArcMap:
http://resources.esri.com/help/9.3/a...ual_earth.htm#

When I check the properties in ArcMap, it says it's "Tiled Internet Layer".
I'm fairly sure it's an ILayer since it can be successfully cast and its properties viewed.
However, I'm not sure which of the CoClasses it belongs to.
I haven't had any luck with IMapServerLayer, IFeatureLayer, IWMSLayer, IImageServerLayer.

it implements interface MapServerLayer but not IMapServerLayer

Thanks for the reply Domenico.

I wasn't able to cast it properly to MapServerLayer.

However, decided on a different solution that'll work for now.
