我正在清除 ASP.NET 临时 Internet 文件，我不小心删除了一些 .NET Framework 文件（我有 3.0、3.5、4.0 和 4.5），然后 Visual Studio 10 或 Visual Studio 2012 都没有打开。我修复了所有 .Net 框架的安装，并且能够再次打开 VS。尽管每个 Web 应用程序都是可构建的，但在尝试运行任何 Web 应用程序时，会出现 web.config appSettings 中的错误，尽管 appSettings 在删除事件之前工作正常。

我不知道出了什么问题以及如何解决这个问题。

IIS 错误：

HTTP 错误 500.19 - 内部服务器错误

无法访问请求的页面，因为该页面的相关配置数据无效。

错误代码

0x80070032

配置错误

无法读取配置部分“appSettings”，因为它缺少部分声明

我遇到过几次这个问题，第一次是 .NET 从 IIS 中“取消注册”

C:\Windows\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -i

修复了该问题（如果不使用 64 位机器，则替换您的 .NET 路径）

导致它的另一件事是当 IIS 应用程序池设置为 .NET 2.0 而不是 .NET 4 时，即使安装了 .NET。只需在 IIS 管理器中打开应用程序池并将其切换回来，它就可以工作了。

这可能意味着您<appSettings>在 web.config 中的位置错误，并且 IIS 认为这是一个自定义部分（因此缺少部分声明），请确保您拥有它，如下所示：

<configuration>
    <appSettings>
    </appSettings>
