The serialization infrastructure heavily relies on type/assembly 
identity, but what you're doing here is trying to create an object
from serialization data generated from a totally different class.

You should implement "Elements" in a separated assembly which you 
reference from both apps. Then, in you "Form", you should aggregate 
Elements, i.e. make it a field, because de/serializing a Form
is not what you want. Really.

public class xmlhandler : Form
{
	Elements theElements;

	public xmlhandler ()
         {
		theElements = deserialize them ...
         }
}
