公开 wcf 服务元数据

Question

我正在关注有关设置 wcf 服务的教程。我完成了它所说的更改，直到它第一次说要启动服务。在我的 Web 浏览器中导航到端点时，我收到 404 或 403.14 错误。最初该服务显示文件夹结构，但我删除了启用该功能的 web.config 文件中的属性。我确定问题与该文件有关，但我不确定还有什么要更改的。 指南链接：http://www.c-sharpcorner.com/UploadFile/dhananjaycoder/four-steps-to-create-first-wcf-service-for-beginners/

我认为 403.14 可能与您的文件夹权限有关。您的应用程序池在什么帐户下运行以及 .NET Framework 的版本？确保您的应用程序池面向 Framework 4.0。 403.14 - 很可能您正在尝试浏览根目录并且目录浏览在 IIS 中被禁用，或者您的应用程序池没有足够的权限。然后，尝试删除协议映射。

在 VS2015 中，您可以将 .svc 文件设置为启动文件。点击“F5”将在 WCF 测试客户端 (WcfTestClient.exe) 中打开该文档。或者，您可以右键单击 .svc 文件并选择“在浏览器中查看”。
