WCF under WSS 3 consume help

Hi, i'm new to sharepoint and am trying to do the following:
i have a wcf service that that i want to comunicate with under WSS 3
using a page i wrote myself.
i have created a simple .aspx web page and put it under \LAYOUTS
library, it works fine under sharepoint.
then i added a wb reference to the web service to a svc file on a
remote computer, (using VS2008). the VS can detect the service
(intellisense working).
I then edited the config.web page in the \80 directory according to :
http://blogs.msdn.com/bgeorgi/archiv...harepoint.aspx
but when i try to run the page again, i get an error :

c:\Program Files\Common Files\Microsoft Shared\web server extensions
\12\TEMPLATE\LAYOUTS\import1\Default.aspx.cs(11): error CS0246: The
type or namespace name 'SR_MyService1' could not be found (are you

i understand that the SR_MyService1 namespace isn't recognized by WSS,
but how do i overcome that?
or is it only possible under MOSS and not WSS?

thanks in advance
