I want to Dynamically Discover Web Services

[John Paul. A]

Hi,

I have a 3rd party web service running in a Web Server within our network.
The web service sends "Hello" message when joins the network and also sends
"Bye" message when leaves the network.
I want to write a client code to receive the "Hello" message as well as the
"Bye" message sent by the web service.
Can you please suggest me a sample code, so that I can discover (dynamically
discover) the web service using the multicast discovery protocol (using
WS-Discovery).

Development Environment : VS 2005, .NET 2.0 and WSE 3.0

Thanks in Advance

You might want to take a look at UDDI (Microsoft SDK).
This is the very place to search for webservices, and ALSO internally on the
network. Win2003 has native support for UDDI directory.

Having a WebSvs posting a "hello"; contradicts everything about SOA.
A service does not inform the clients that it is ready as the service does
NOT know about it's clients. Should it know about its clients, you are tying
your system too hard together.

Use the UDDI to query for active services, if you insist.
