When passing an IEnumerable to SaveChangesAsync, are the associated entities saved as well?
 
ie:
 
A Project entity has an associated list of Contacts.
 
em.SaveChangesAsync(Projects, callback);
 
Are the Contacts saved as well?

Hi MVenhola,
 
When you are doing a 'partial' save, only the entities passed on to the save are actually saved:
 
If you want to also save the contacts, you will need to pass them to the SaveChanges call.
 
In the http://drc.ideablade.com/xwiki/bin/view/Documentation/save-dependency-graph - DevForce Resource Center you will find an article on saving a graph of entities.
 
Regards,
