Every once in while after a big release, the question comes to your mind, what's next? Well for me it is WS-Discovery, yes I am going to work on design and implementation of the web service discovery APIs for our next release. I have been involved been Discovery for a while including the WS-discovery specification work. I plan to release the sample implementation of WS-Discovery on top of .NET 3.0 on the netfx3.com community site soon. I would love to hear about your disovery requirements and scenarios, so that we can consider them in our design.
