You are adding a Windows Communication Foundation (WCF) service to an existing application. The application is configured as follows. (Line numbers are included for reference only.)
01 <configuration>
02 <system.serviceModel>
03 <services>
04 <service name=”Contoso.Sales.StockService”
05 behaviorConfiguration=”MetadataBehavior”>
06 <host>
07 <baseAddresses>
08 <add baseAddress=”http://contoso.com:8080/StockService” />
09 </baseAddresses>
10 </host>
11 </service>
12 </services>
13 <behaviors>
14 <serviceBehaviors>
15 <behavior name=”MetadataBehavior”>
16 </behavior>
17 </serviceBehaviors>
18 </behaviors>
