WCF - Publisher / Subscriber - Event

Is it possible to implement a publisher / subscriber model in WCF with events only (i.e. not lists or dictionaries)?

If so, plz will provide me with a link to the sample app web page or any article that talks about it.

Yes. There is an MSDN article here that's all about it.

Events are not possible in WCF. You have to use Callback-Contracts . Here you can find some information about the Publisher / Subscriber-Pattern template in WCF.

I would like to direct you to Juval Lowy's site, IDesign.net . He is the author of what is arguably the definitive WCF book, Programming WCF Services . His website is full of all kinds of examples that are freely available, including the WCF publishing workbench. Find the Publish-Subscribe Framework in the Downloads area.
