>>Hmm. This is, in a way, related to the thread from yesterday. If you make the type of Client.Something 'Damage' and assign an instance of Damage to it then you will be sending the whole object over the wire within Client. If you only need the Damage.Drivable property then make Something a bool (I assume) and keep your code as is.

No. You can new up an existing type or an anonymous type - no other options. Well you could go down the DLR route (but I don't like it):

var anon = clients.Select(x => new { Surname = x.LastName, GivenName = x.FirstName }).FirstOrDefault();
DoSomething(anon);

Then:

   void DoSomething (dynamic d)
    {
        string Surname = d.Surname;
    }

(Sorry C# version but conversion should be simple)
