如何让 <configSections> <runtime> inside <configuration> 一起工作

How can I make <configSections> <runtime> inside <configuration> work together

这是我的 WPF 应用程序中的 app.config:

    <?xml version="1.0" encoding="utf-8"?>
    <configuration>
      <configSections>
        <sectionGroup name="userSettings" type="System.Configuration.UserSettingsGroup, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">
          <section name="XXX.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" allowExeDefinition="MachineToLocalUser" requirePermission="false"/>
        </sectionGroup>
        <sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">
          <section name="XXX.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false"/>
        </sectionGroup>
      </configSections>

      <userSettings>...</userSettings>
      <applicationSettings>...</applicationSettings>

      <startup>
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6.2"/>
      </startup>

      <runtime>
        <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
          <dependentAssembly>
            <assemblyIdentity name="System.ValueTuple" publicKeyToken="cc7b13ffcd2ddd51" culture="neutral" />
            <bindingRedirect oldVersion="0.0.0.0-4.0.2.0" newVersion="4.0.3.0" />
          </dependentAssembly>
        </assemblyBinding>
      </runtime>
    </configuration>

运行 应用程序获取异常:

ConfigurationErrorsException: Only one element allowed per config file and if present must be the first child of the root element

如果我删除 <runtime> 部分应用程序运行良好 但会导致构建时间警告:

解决方案:

所以我的问题是 如何让 "configSections" "runtime" 在 "configuration" 中协同工作

我没有看到一起使用 <runtime><configSections> 有任何问题(我做了 2用它做项目,两者都可以。

我不知道你用下面的部分配置了什么,也许你的问题就在里面:

      <userSettings>...</userSettings>
      <applicationSettings>...</applicationSettings>

尝试清理并重建解决方案。
