That's interesting, if it's not good practice to send back entities over WCF, then why is WCF Data Services around? That's a curious question I have.
I'm just reporting what my books say. I generally agree with them for large scale apps. Entity Framework 4 In Action <http://www.amazon.com/Entity-Framework-Action-Stefano-Mostarda/dp/193518218 8> Entity Framework <http://www.amazon.com/Programming-Entity-Framework-Julia-Lerman/dp/05965202 8X> I reckon WCF Data Services are just another one of those so-called RAD hobby toys that Microsoft trotted out to impress people at SIGs. I wouldn't create a monolithic app with that stuff if you paid me ... well, maybe if you paid me! Greg
