We use this:

return Context.ObjectStateManager.GetObjectStateEntries(System.Data.EntityState.Deleted
System.Data.EntityState.Modified).All(ose

    if(ose.Entity != null)
      Context.Refresh(RefreshMode.StoreWins, ose.Entity);
      return true;
    });

Where "Context" is the context to refresh. We filter by change state and entities to avoid new entities and relations.
