Are you using the latests WCF Facility (trunk)? Did you look at the MEX and
Discovery unit tests?
BTW you should FindCriteria.CreateMetadataExchangeEndpointCriteria to discover
MEX.
Also, the WCF Facility can now resolve all A, B & C (Address, binding,
Contract) with single discovery call. All you need to do is use the
WcfEndpoint.Discovered()
