有没有办法通过多个服务激活添加WCF svc-less激活？

Question

给出以下配置：

<serviceHostingEnvironment multipleSiteBindingsEnabled="true" >
    <serviceActivations>
        <add relativeAddress="./UserService.svc" service="Mercato.KnowledgeKube.WebSvc.Service.KnowledgeuserManagerService" factory="Mercato.KnowledgeKube.WebSvc.WCF.KnowledgeServiceHostFactory" />
        <add relativeAddress="./ProductService.svc" service="Mercato.KnowledgeKube.WebSvc.Service.ProductManagerWebServices" factory="Mercato.KnowledgeKube.WebSvc.WCF.KnowledgeServiceHostFactory" />
   </serviceActivations>
</serviceHostingEnvironment>

两个./UserService中的第一个是可以访问的，我可以创建一个服务引用，但ProductServce不可协调。我在这里做错了什么？

修改

这是例外：

 There was no endpoint listening at http://localhost/KnowledgeWebService/ProductService.svc that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.
The remote server returned an error: (404) Not Found.
If the service is defined in the current solution, try building the solution   
and adding the service reference again.

Answer 1

没有端点监听，因为......我没有用相关属性来判断产品服务。我首先在寻找更复杂的问题。
