Hi, I would appreciate a brief point in the right direction. I'm looking at a Smart Client design with a windows client using Microsofts offline block etc, connecting back to a Web Service fronting an application server. My current plan is to use nhibernate to provide persistance to the application's server domain model. I'm familiar with serialization etc and the domain model is serializable etc.

I have played a little with nhibernate and the old Northwind.

I can see how objects that have been created with in nhibernate could be serialized to the remote client.

I know how to get the objects back via the web service.

The points I still need to grasp (I'm sure they are elementary if you know where to look) are:

1) how to return objects back into the nhibernate session?
2) is this process any different for objects originated from the session verse object created out side the session by the smart client.

I would much appreciate some pointers even if it is a reference on where to read.

When the objects are being deserialized in the webservice (for example after editing in your Smart Client), you can add them to a new session with ISession.Update(). I believe the latest NHibernate has a ISession.SaveOrUpdateCopy() method that should make this even work better. Don't know the details about this yet.

Thanks for responding. I will have a play over the next few days and report back. I will naturally keep an eye on the forum for more input should it come forth.

Again,

Many thanks for responding.

No, there is no difference at all; as long as you understand when an entity is be viewed as transient by NHibernate.
