Consider the following updated host *.config file, which creates a custom  element

(named EightBallMEXBehavior) that is associated to our service via the behaviorConfiguration

attribute within the  definition:

behaviorConfiguration = "EightBallServiceMEXBehavior">

binding="basicHttpBinding"

contract="MagicEightBallServiceLib.IEightBall"/>

binding="mexHttpBinding"

contract="IMetadataExchange" />

You are now able to restart the service and view its metadata description using the web browser

of your choice. To do so, while the host is still running simply enter the address as the URL:

http://localhost:8080/MagicEightBallService 

Once you are at the homepage for your WCF service (see Figure 25-7), you are provided with

basic details regarding how to interact with this service programmatically as well as a way to view

the WSDL contract by clicking the hyperlink at the top of the page. Recall that Web Service Descrip-

tion Language (WSDL) is a grammar that describes the structure of web services at a given

endpoint.
