DotNet Visual Basic: IDeserializationCallback

• In Jeffrey Richters article on Serialization--part 2 from MSDN 2002, he
  mentions that "IDeserializationCallback....When this method is called, all
  objects have had their fields set. But there's no way to tell what order
  multiple objects have their OnDeserialization called. so, while the fields
  may be initialized, you still don't know if a referenced object is
  completely deserialized if that referenced object also implements the
  IDeserializationCallback interface."

  I have a form that has a specific collection class as a private member.
  The objects in that collection have a member variable that references the
  form on which the collection class is.
  After deserialization, I need to reset this member variable.

  How can I best do it?

  If I can't trust IDeserializationCallback, is there a way to call the
  deserialization for the collection on the form, and the code not continue
  executing until this call is made, and thus after the call comes back, I can
  call a method on the collection class to set all items' ParentForm property
  in the collection?

  Does the vb code execute asynchronously here (i.e. the next thing would
  never happen until the deserialization call is finished)? I think this is
  the case unless it is a multithreaded app.

  Any thoughts?

  Thanks,

  Shane
