hey everyone, thought I would ask this here because the web service groups
seems pretty light on conversation. I'm buliding a web service, but keep
getting this error. I understand the error, read a work around, but don't
know if its the best approach.

Here is a link to the error... at least a description.

http://support.microsoft.com/default.aspx?scid=kb;en-us;814187

i'm confused though. I looked at Icollection, and there is no Add Method.
So don't know what to do here. I thought I would inherit from
nameobjectbase and then override the Add method but there is no add to
override.

Suggestions?

here is a complete stack dump of the error.
