Config Builder 找不到环境变量

Question

调试时查看连接字符串，值为“abc”；不是我设置的 Windows 环境变量。

web.config

<configSections>
  <section name="configBuilders" type="System.Configuration.ConfigurationBuildersSection, System.Configuration, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" restartOnExternalChanges="false" requirePermission="false" />
</configSections>

<configBuilders>
   <builders>
      <add name="Environment" type="Microsoft.Configuration.ConfigurationBuilders.EnvironmentConfigBuilder, Microsoft.Configuration.ConfigurationBuilders.Environment, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
   </builders>
</configBuilders>

<connectionStrings configBuilders="Environment">
   <add name="myConnection" connectionString="abc" providerName="System.Data.SqlClient"/
</connectionStrings>

我仔细检查了是否安装了正确的 Nuget 包，框架在 4.7.2 上是否正确，我的拼写是否正确，并且我已经多次阅读 Configuration Builders 上的 Microsoft 文档.

Answer 1

在上面链接的 Microsoft 文档中，Configuration builders for ASP.NET，存在以下脚注：

Note: You might need to exit and restart Visual Studio to see changes in environment variables.

已修复。
