我将逐步完成到目前为止我所做的如下:

创建空解决方案

添加了一个网站 WCFService

从网站

中删除了 Service 和 IService

在解决方案中添加了 WCF 服务库项目

添加端点到 web.config

在 app.config 中做了同样的事情

在 Web 应用程序中添加了对服务库的引用

查看网站项目中的 WF_Ledger.svc 文件。它应该只包含一行。会有包含“Services.WFAPILedger.WF_API_Ledger”的服务属性。 WCF 正在寻找“Services.WFAPILedger.WF_API_Ledger”类，但没有找到。命名空间和类名需要存在于网站项目中，或者在您尝试设置时作为引用。您需要编辑该 Service 属性以匹配 WCF 服务库项目中的服务实现类。
