find-method doesn't respond a UUID

Hi,

usersguid works pretty good. 
But when I do a find on my MS SQL DB then it responds the GUID as String like "{99999999-9999-9999-9999-999999999999}" with the "{}". Because auf this I can't .parse it to a GUID.
How to get a GUID by the find-method?

Thanks you very much
Stueck
