我在我的开发箱上设置了WCF服务,但访问时遇到错误.我已经设置了
service up as per this guide.它是用VS2008 / C#/ .NET 3.5编写的,我的开发盒是带有IIS 7的Vista SP2.目前该服务只不过是默认结构,因为我在测试连接到它.
我已经检查了需要安装的内容,我很确定我已经启用了所有内容,下面的屏幕截图显示了当前的选项：
访问http://localhost:8000/Service.svc时出现完整错误消息如下：

我们将非常感激地提出有关如何调试/修复错误的任何建议.谷歌搜索错误提供的帮助很少.我可能错过了一些非常明显的东西！
编辑 – web.config按要求(对其长度道歉)：

编辑2 – 我删除了关于创建Delphi Win32客户端的段落,因为Delphi 2007不支持SOAP 1.2,这是WCF服务使用的. Delphi 2007仅支持SOAP 1.0 …因此客户端现在将成为C#WinForms应用程序.
解决方法
我的答案如下(由Lazarus在评论中提供,但未作回答发布)：
>已启动Internet信息服务(IIS)管理器.>打开“站点”文件夹并选择相关站点.>右键单击它,然后选择管理网站,然后选择高级设置…>在弹出的结果中,我在Enabled Protocols行中输入了http.>关闭弹出窗口并重新启动站点,就是这样.固定！
