Is there an actionscript 3 to webservice WCF class?

Question

Hi,

I need to comunicate with a webservice (WCF) from actionscript 3 (not Flex). I've been searching the Internet a lot and found http://flashauthoring.blogspot.com/2008/10/using-flex-webservice-component-in.html, but it works only in Flash Professional and I'm using Flash Builder 4 to compile the project. code.google.com/p/as3webservice/ works but not for WCF. Has anybody written a class that will work in my scenario?

Thanks for all responses, TR
