Search for WCF service in a LAN?

Question

Is there a way to search for the existence of a given WCF service in any of the computer of a local Network?

For example, I am looking for the Math/Add2Numbers service and I want to know which machines on the LAN provide it, is there any way to do that?

Answer 1

What you need is WS-Discovery, but unfortunately, this is not included as part of the ws-* extensions in WCF. There are some homegrown implementations of it. Here's a google search for that.

Otherwise, you can implement an enterprise UDDI or registry solution by a third party vendor (like IBM or Microsoft).

Answer 2

You could use UDDI to find it, but if there were multiple instances of the service, how would you decide which instance to use?
