>Not sure I understand. You are still creating an instance of ClientAPI.ClientService.Client and all of its fields will be present. The only difference is that everything other than FirstName and LastName will have default values.

Well, the foreign provider wants us to adjust those Linq queries to collect only the required fields and not returning the entire record. Does this mean I have more adjustment to do here?

As if this returns the entire record, but empty values for the other fields, I am not better than before. lol
