Dpws web service with event - Wcf client example or suggestions sought - wcf

Question

My device has a DPWS web service with a single output (wsdl:output) that I need to subscribe to with a Wcf client
The client is a regular .Net 4.0 application - not .net-micro-framework.
I need an example or tutorial or other resource relating to building such a client to such a service.
'Add Service Reference' produces non-working code, 'Add Web Reference' hangs.
The Wsdl is below.
If there's any further information required to answer this question please let me know.
Many thanks

Single Output means that this service generates Events. You will want to look for WS-Eventing. It is not supported in stock .Net 4.0 WCF, but a project on CodeProject is implementing this functionality on top of WCF. Are you still interested in this topic?
