.net - 配置系统无法初始化/无法识别配置节 <SectionName>

Question

我在新安装的桌面上调试以下代码。检查我的环境很简单。 我通过互联网搜索了该错误，但没有答案可以解决我的问题。我猜可能是文件系统权限造成的。

static void Main(string[] args)
{
    string test = ConfigurationManager.AppSettings["aaa"].ToString();
    Console.WriteLine(test);
}

App.config 看起来像:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <appSettings>
    <add key="aaa" value="bbb" />
  </appSettings>
</configuration>

我收到如下错误:

System.Configuration.ConfigurationErrorsException: Configuration system failed to initialize ---> System.Configuration.ConfigurationErrorsException: Unrecognized configuration section appSettings
