metadata exchange

A beginner's silly question.

If I want to add a metadata exchange endpoint for a sevice.

Where should be placed?
Client side?Host side or proxy side?


Thanks

Well first things first, client side and proxy side are the same thing as you use the proxy to communicate from the client to the server :)

Anyway, adding a metadata endpoint (aka MEX endpoint) is done on the server side, or host side as you have called it.
I can show you how to do it if you explain whether you are hosting your WCF service via Config file or via code (ie manually calling Open on a ServiceHost class instance in code) ?

If you look at your config file, you should see a mex address binding already there. It's done for you. You can choose to hide it later if you want.
