I've got an object that contains an EntitySet using a specific key that is fixed for the lifetime of the application.

I would like this to materialize in the constructor; so I'm doing this:

pendingList  = session.Query.SingleOrDefault<NotificationList>(Queue_ID);

if (pendingList == null)
    pendingList = new NotificationList(Queue_ID);

Is this the right way of doing this. The Queue_ID is a const string, and pendingList is an Entity.
