问题描述

出于某种原因，我不能让过去的这个错误。我做了搜索，但找不到任何VB实例。我是什么不对的web.config文件做什么？

解决方案

服务属性必须实现，而不是接口。

 ＆LT;％@ ServiceHost的语言=VB调试=真正的服务=SalesTracking.WebService......
 

For some reason I can't get past this error. I've done searching, but can't find any vb examples. What am I doing wrong with this web.config?

SalesTracking.svc

<%@ ServiceHost Language="VB" Debug="true" Service="SalesTracking.ISalesTracking" CodeBehind="SalesTracking.svc.vb" %>

解决方案

Service attribute must be the implementation, not interface.

<%@ ServiceHost Language="VB" Debug="true" Service="SalesTracking.WebService" ....
