I have a passenger entity collection and a service entity collection.
Both get added to a Booking entity
I have a bridging entity ServicePassenger containing columns Passenger_ID and Service_ID.
Passengers are assigned to each service on a booking.
When I save, do I have to add ServicePassenger to both the Passenger and Service entities. Obviously Passengers and Service need to be created before the necessary identity column values to be retrieved for ServicePassenger.Passenger_ID and SericePassenger.Passenger_ID.
