Enable the Serializer to create an array of arrays, rather then an array of objects so instead of having
[{"$type":"ucICO.Entities.TUser","$id":1,"FName":"John"},{"$type":"ucICO.Entities.TUser","$id":2,"FName":"Fred"}]
you can have
[[1,"John"],[2,"Fred"]]
This is useful for web applications, although obviously not for desrialization.
