Row not found or changed... meet ChangeConflictException handler!

Row not found or changed exceptions are frustrating... until now!

catch (ChangeConflictException cce)
{
    // Where DB is your database context
    foreach (ObjectChangeConflict occ in DB.ChangeConflicts)
    {
        MetaTable metatable = DB.Mapping.GetTable(occ.Object.GetType());
        Debug.WriteLine("\nTable name: " + metatable.TableName);
        foreach (MemberChangeConflict mcc in occ.MemberConflicts)
        {
            Debug.WriteLine("Member: " + mcc.Member);
            Debug.WriteLine("\tCurrent  value: " + mcc.CurrentValue);
            Debug.WriteLine("\tOriginal value: " + mcc.OriginalValue);
            Debug.WriteLine("\tDatabase value: " + mcc.DatabaseValue);
        }
    }
    throw;
}
