Explanation:
<system.serviceModel>
<services>
<service behaviorConfiguration=”WcfServiceLibrary1.Service1Behavior” name=”WcfServiceLibrary1.Service1″>
<endpoint address=”” binding=”netTcpBinding” bindingConfiguration=”” contract=”WcfServiceLibrary1.IService1″>
<identity>
<dns value=”localhost” />
</identity>
</endpoint>
<endpoint address=”mex” binding=”mexTcpBinding” bindingConfiguration=”” contract=”IMetadataExchange” />
<host>
