C#Webservice：接口定义和web.config问题

我正在从事一项网络服务。当我尝试从visualstudio2013启动它时，现在出现以下错误：“未能添加服务。服务元数据可能无法访问。请确保您的服务正在运行并公开元数据。”

有人有潜在的解决方案吗

以下是此Web服务的界面：

namespace WebService
{
[ServiceContract]
interface IWebService
{
    [OperationContract]
    [WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Xml,
                                RequestFormat = WebMessageFormat.Xml,
                                BodyStyle = WebMessageBodyStyle.Wrapped,
                                UriTemplate = "/tasks")]
    List<SwitanceTask> getTasks(string groupD, DateTime date);

    [OperationContract]
    [WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Xml,
                               BodyStyle = WebMessageBodyStyle.Bare,
                               UriTemplate = "/time")]
    DateTime getWebServiceTime();

    [OperationContract]
    [WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Xml,
                                RequestFormat = WebMessageFormat.Xml,
                                BodyStyle = WebMessageBodyStyle.Bare,
                                UriTemplate = "/upd")]
    int updateTask(SwitanceTask task);

    [OperationContract]
    [WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Xml,
                               BodyStyle = WebMessageBodyStyle.Bare,
                               UriTemplate = "/grp")]
    List<SwitanceGroup> getGroups();

}}

命名空间Web服务
{
[服务合同]
接口IWebService
{
[经营合同]
[WebInvoke（Method=“POST”，ResponseFormat=WebMessageFormat.Xml，
RequestFormat=WebMessageFormat.Xml，
BodyStyle=WebMessageBodyStyle.Wrapped，
UriTemplate=“/tasks”）]
列表任务（字符串groupD，DateTime-date）；
[经营合同]
[WebInvoke（Method=“GET”，ResponseFormat=WebMessageFormat.Xml，
BodyStyle=WebMessageBodyStyle.Bare，
UriTemplate=“/time”）]
DateTime getWebServiceTime（）；
[经营合同]
[WebInvoke（Method=“POST”，ResponseFormat=WebMessageFormat.Xml，
RequestFormat=WebMessageFormat.Xml，
BodyStyle=WebMessageBodyStyle.Bare，
UriTemplate=“/upd”）]
int updateTask（SwitanceTask任务）；
[经营合同]
[WebInvoke（Method=“GET”，ResponseFormat=WebMessageFormat.Xml，
BodyStyle=WebMessageBodyStyle.Bare，
UriTemplate=“/grp”）]
列出getGroups（）；
}}

这是我的配置：

您的WCF服务项目是否像在IIS/IIS Express中一样运行？它在IIS Express中运行（visual studio中的默认选项）。是的，我的意思是检查WCF项目是您的解决方案的一部分还是在其他地方单独托管
