Where can I find a good Silverlight 4 WCF duplex tutorial?

Question

I'm interested in seeing a good example of a duplex service that a Silverlight 4 application connects to, is there one out there? I'm willing to get a book if it's located in it.

I went though the MSDN one located here and didn't follow it very well, or even get it working.

2 best examples I've found:

some good info -- http://tomasz.janczuk.org/2009/11/wcf-nettcp-protocol-in-silverlight-4.html

Hope that helps --
