"Reference required to assembly 'RootLevel' containing the type 'RootLevel.Root'. Add one to your project."

While building on a class library for an object model, I get the above error

The steps to recreate the problem are as follows:

1. Build a RootLevel.dll containing only this code:

Public Class Root
End Class

2. Build a SecondLevel.dll containing a reference to RootLevel.dll and only
this code:

Public Class Child
Private _root As RootLevel.Root

Public Property Root() As RootLevel.Root
Return _root
End Get
Set(ByVal value As RootLevel.Root)
_root = value
End Set
End Property
End Class
3. Edit the Root class, add a reference to SecondLevel.dll and Re-build the
RootLevel.dll. The edited code looks like this:

Public Class Root
Private _child1 As SecondLevel.Child 'there will be other children

Public ReadOnly Property Child1() As SecondLevel.Child
If _child1 Is Nothing Then
_child1 = New SecondLevel.Child()
_child1.Root = Me
End If
Return _child1
End Get
End Property
End Class

The reference to 'Me' is marked with the following error by the Visual
Studio.NET IDE:
"Reference required to assembly 'RootLevel' containing the type
'RootLevel.Root'. Add one to your project."
Obviously, this a simplified example, where children are plugged into the
root as needed. The children can be pretty complex and considerably
different from each other. Children need to reference the root, and children
often need to reference each other.

How do I work around this circular compilation reference situation or
whatever is going on here?
