title: If Base class is marked Serializable are all child classes marked too?
body: <p>I have a whole list of entity classes which I need to make Serializable (due to storing session state in SQL, but that's another story). </p>
  
  <p>I have added the attribute [Serializable] and all seems to be fine.</p>
  
  <p>All of my entity classes extend from the same base class. 
  If I mark the base class as Serializable, does this mean all children are marked as Serializable too?</p>
  
  <p>Thanks</p>
