c# - 无法读取配置部分 'system.serviceModel'，因为它缺少部分声明

Question

我们已经使用 .Net 4.5 在 Visual Studio 2013 中创建了一个网络服务。该网络服务在同一台计算机上本地运行良好。

现在我们想将此 Web 服务导出到带有 IIS 的 Windows Server 2008。我们已经制作了一个在端口 8080 上运行的 Web 服务。

但是当我们将导出的文件复制到这个网络服务器的根目录时，出现了以下错误:

Error Summary 
HTTP Error 500.19 - Internal Server Error

The requested page cannot be accessed because the related configuration data for the page is invalid.

Config Source    10:   </system.web>

我们在Visual Studio中导出的webconfig是:

这个生成的配置文件有什么问题？

从 .Net Framework 4 开始，服务行为不需要名称 ( MSDN )。在 .Net 4 之前，它是强制性的。因为你的服务行为没有名字:

<serviceBehaviors>
    <behavior>
        <!-- name attribute missing in behavior -->
    </behavior>
</serviceBehaviors>

并且 IIS 抛出错误我怀疑您的应用程序池未运行 .Net 4 或更新版本。
