Building an ad-hoc auto-discoverable service
In some service hosting environments, the endpoint address of each hosted service is dynamic or frequently changing; or some services will constantly change their base address after every service or server restarts. In such cases, it is quite important to let the service client be able to dynamically discover the service location. Fortunately, WCF 4 provides a new feature called service discovery, which can properly address this issue. The discovery feature enables services to be discoverable at runtime in an interoperable way using the WS-Discovery protocol. WCF services can announce their availability to the network using a multicast message or to a discovery proxy server. Client applications can search the network or a discovery proxy server to find services that meet a set of criteria. In this recipe, we will cover how to build a simple and powerful ad-hoc auto-discoverable service through the service discovery feature.
