WCF / ASP.NET MVC : Supporting events from WCF to asp.net MVC or similar concept?
===

I would like to simulate events from a WCF Service, is this at all possible? I have heard about DUPLEX WCF (2 way calling) but maybe there is  a better way.

Here is what i need to do, from my ASP.NET MVC app, i need to initiate a call to the WCF Service, for this call to complete it can take a very long time hence it would timeout. I would like to pass the call to WCF and return back to the web page where i can inform the client that the process is running. I need to be able to receive events (or similar concept) on asp.net mvc to inform the client where it is at and how the progress is going.

WCF 2 WAY Duplex calling sounds good, otherwise maybe having Jquery call (on a timer) to get the process... Althouhg i think this wouldn't work. I really need some kind of event driven model to work with WCF ..

Any help really appreciated

Thanks in advance
