Unit Testing and XML serialization

 

I have been able to serialize OUT to XML an instance of one of my Entity based classes.  But the Deserialization fails with a Null Object Reference.  Below is the exception. It looks like it is failing trying to find the EntityGroup for the object being created.  Yet where was no group when it was serialized.  It was created in code without an entity manager or group
