Subclass RouteEventSource

[ShaningYu]

In ESRI's Exploring ArcObjects, Vol. 1 p967, it is stated that the RouteEventSource is subclass of a Feature Class.  However, in VS 2010 Object Browser, it is an interface (see the attached image).  I wish ESRI Developer Team take a look on it.

RouteEventSource is a non-creatable coclass, not an interface.  All interfaces in the ArcObjects model have a name that begins with "I".

Neil:  You are right - It is a co-class.  But it displays as an interface in VS 2010 Object Browser (see the image in my 1st post).  There is something incorrect.  How do you think?  Thanks for your feedback.  Shaning

Reviewed VS Object Browser again and found that I mis-understood something there.  I should view the RouteEventSourceClass (the co-calss) Will close this thread.
