Hello,

I have trawled the web looking for an answer for this but cannot find any clear and concise answer:

I have a system with three main tiers: Data Layer, Business Layer, UI Layer (ASP.NET). The Data and Business layers are delivered via WCF. Currently the Business and UI layers have no dependency on NHibernate.

Is it possible to pass entities to the UI and still take advantage of lazy-loading across WCF? If so can anybody point me in the direction of a clear article/code example that demonstrates how this would be achieved? I'm aware that in order to achieve this I will break some SOA rules and that my client will require a dependency on NHibernate. I am not currently using any IoC mechanism within the project.

Thanks in advance, Carl

I haven't been able to figure out how to do it other than via data transfer objects. If there is an elegant solution, I'd like to know too.

This post has helped clear things up... it seems that it's simply not a good idea to separate the tiers at this level:
