第四步:配置WCF服务
在Services项目中右击“App.Config”配置文件,在弹出的右键菜单中选择“编辑WCF配置”。
单击左侧的“服务”-“Wcf_MassData.DataTransfers”在右侧的Name,弹出“服务类型浏览器”对话框,在此类型中我们找到此WCF服务项目编译出来的Wcf_MassData.dll文件,双击它就可以出现此服务中的对外公布的服务,点击选中它单击确定。
这样我们就可以把对外公司的服务改变为我们刚编写的服务了。
然后,我们展开左侧“服务”->“Wcf_MassData.DataTransfers”->“终结点”,单击第一个“空名称”,从右边的“终结点属性”中的Contract中我们可以看到,这里的Contract仍然用的是Services.IService1。
那我们按照上面的做法,找到此WCF服务项目编译出来的Wcf_MassData.dll,双击它找到里面对应的ServiceContract点击确定就可以了。

点击菜单“文件”-“保存”就可以把我们对App.Config的修改保存回配置文件了。
OK,现在我们对WCF的配置算是完成了。
App.Config代码:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>

    <system.web>
        <compilation debug="true" />
    </system.web>
    <!-- When deploying the service library project, the content of the config file must be added to the host's
    app.config file. System.Configuration does not support config files for libraries.
-->
    <system.serviceModel>
        <services>
            <service name="Wcf_MassData.DataTransfers">
                <endpoint address="" binding="wsHttpBinding" contract="Wcf_MassData.IDataTransfers">
                    <identity>
                        <dns value="localhost" />
                    </identity>
                </endpoint>
                <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
                <endpoint address="basic" binding="basicHttpBinding" bindingConfiguration=""
                    contract="Wcf_MassData.IDataTransfers" />
                <host>
                    <baseAddresses>
                        <add baseAddress="http://localhost:8732/Design_Time_Addresses/Wcf_MassData/Service1/" />
                    </baseAddresses>
                </host>
            </service>
        </services>
        <behaviors>
            <serviceBehaviors>
                <behavior>
                    <!-- To avoid disclosing metadata information,
                    set the value below to false and remove the metadata endpoint above before deployment
-->
                    <serviceMetadata httpGetEnabled="True"/>
                    <!-- To receive exception details in faults for debugging purposes,
                    set the value below to true.    Set to false before deployment
                    to avoid disclosing exception information
-->
                    <serviceDebug includeExceptionDetailInFaults="False" />
                </behavior>
            </serviceBehaviors>
        </behaviors>
    </system.serviceModel>

</configuration>
