.net 如何在更改WCF服务应用程序项目中的命名空间时运行WCF服务？

我已将“WCF服务应用程序”项目类型添加到我的VS解决方案（4.0）中。现在，出现的默认名称空间是“Service”，如果我运行该应用程序（将WCF服务应用程序作为启动项目），它可以正常工作

现在，我将名称空间更改为XXX.YYY.Service.PartnerPortal，如下所示

namespace XXX.YYY.Service.PartnerPortal
{        
    public class Service1 : IService1
    {
        public string GetData(int value)
        {
            return string.Format("You entered: {0}", value);
        }        
    }
}

以及IService1接口

namespace XXX.YYY.Service.PartnerPortal
{    
    [ServiceContract]
    public interface IService1
    {
        [OperationContract]
        string GetData(int value);        
    }
}

此外，我还更改了项目属性中的默认名称空间

app.config文件如下所示

<?xml version="1.0"?>
<configuration>
    <system.web>
        <compilation debug="true" targetFramework="4.0">
        </compilation>
        <pages controlRenderingCompatibilityVersion="3.5" clientIDMode="AutoID"/></system.web>
    <system.serviceModel>  

    <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>
        <serviceHostingEnvironment multipleSiteBindingsEnabled="true"/>
    </system.serviceModel>
    <system.webServer>
        <modules runAllManagedModulesForAllRequests="true">
        </modules>
    </system.webServer>
</configuration>

版本信息：微软.NET框架版本：4.0.30319；ASP.NET版本：4.0.30319.272--.

我做错了什么以及如何修复它？

更改了配置文件，如下所示

<system.serviceModel>
        <services>
            <service behaviorConfiguration="Service.Service1Behavior" name="XXX.YYY.Service.PartnerPortal.Service1">
                <endpoint address="" binding="wsHttpBinding" contract="XXX.YYY.Service.PartnerPortal.IService1">
                    <identity>
                        <dns value="localhost"/>
                    </identity>
                </endpoint>
                <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
            </service>
        </services>
        <behaviors>
            <serviceBehaviors>
                <behavior name="Service.Service1Behavior">
                    <!-- 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>

打开svc文件，并更正服务属性值中的名称空间

<%@ ServiceHost Language="C#" Debug="true" Service="XXX.YYY.Service.PartnerPortal.Service1" .....
