excellent idea, i solved tha same problem (of partially loading entities and pushing them with wcf) using projections, but the use of projections has certain limitations mainly to as to what level of the object graph can someone load.
has anybody tested what happens if we send the partially loaded object back for update? thank you, giannis On 2 Φεβ, 15:58, "[email protected]" <[email protected]> wrote: > What you need is a data contract serializer to push data across the > pipe (the example below is only for outgoing).
