如何在WCF服务应用程序项目中更改名称空间时运行WCF服务？

Question

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,出现的默认命名空间是" Service ",如果我运行应用程序(将WCF服务应用程序指向启动项目),它可以正常工作.

现在我已将命名空间更改为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接口也是如此

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

我还更改了项目属性中的默认命名空间

app.config文件如下

<?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>

在尝试运行时,我收到的错误消息是

我在做什么错,怎么解决？

打开svc文件,并更正Service属性值中的命名空间

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