WFC Data Service should suport this kind of modeling.
Jorge Ortiz commented
Almost every merely complex data model includes some inheritance, so, WFC Data Service should suport this kind of modeling.
This seems to be sort of implemented in EF 4.1 & WCF Data Services CTP2 as of Apri/June 2011
Marcel Šerý commented
This is really an essential functionality for enterprise modelling.
francesco leonetti commented
Real world domains contain derived types and navigation to derived types. EF DO fully support them; WCF Data Services DON'T: really big shame because this leads to a painful integration process when trying to expose models through OData protocol.
Jerome Haltom commented
Yeah. Really. This WCF Data Services thing simply not working with EF sort of sucks. What's worse is there's no way to load this type without the navigation properties, the only work around is to go break your model... which may be shared by other apps. Not cool.
