ConfigurationManager 存在于 System.Configuration.ConfigurationManager 和 System.Configuration 中

Question

我正在努力将我们的一个公共库移植到 NET Standard 2.0。

现有库在多个区域使用旧的 ConfigurationManager 访问 app.config 文件。

我在 System.Configuration.ConfigurationManager 的预发布版本中添加了它，当 netstandard 2.0 被 selected 时，它可以很好地解决问题。但是当我 select net461 抛出错误时：

Severity    Code    Description Project File    Line    Suppression State
Error   CS0433  The type 'ConfigurationManager' exists in both 'System.Configuration.ConfigurationManager, Version=4.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51' and 'System.Configuration, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' Synovia.Service.Common.Core(net461) C:\git\synovia.service.common\Common\EmailHelper.cs 15  Active

查看我的参考资料，我没有看到我在哪里引用了两者。有没有人遇到过这个问题，你是如何解决的？

搜索答案的所有尝试都会导致 .NET 2.0 答案等

编辑 - 当前参考文献 如您所见，我没有引用 System.Configuration 的地方。只是 System.Configuration.ConfigurationManager.

Answer 1

我不知道此列表中的其他依赖项，但您在此处引用了 ServiceStack 的 .NET Framework 依赖项：

<PackageReference Include="ServiceStack" Version="4.5.12" />
<PackageReference Include="ServiceStack.Text" Version="4.5.12" />

它确实依赖于 System.Configuration。要引用 ServiceStack 的 .NET Standard 包，您需要改为引用：

<PackageReference Include="ServiceStack.Core" Version="1.0.43" />
<PackageReference Include="ServiceStack.Text.Core" Version="1.0.43" />

如果您同时针对 .NET Framework 和 .NET Standard，则需要在各自的平台下引用这两个依赖项。

我终于搞定了。提出的所有建议都帮助我朝着正确的方向前进。主要问题是我有一个参考试图拉错 System.Configuration。整理完所有内容后，我将其添加到我的 csproj

  <ItemGroup Condition=" '$(TargetFramework)' == 'net461' ">        
    <Reference Include="System.Configuration" />
  </ItemGroup>
  <ItemGroup Condition=" '$(TargetFramework)' == 'netstandard2.0' ">
    <PackageReference Include="System.Configuration.ConfigurationManager" Version="4.4.0-preview1-25305-02" />
  </ItemGroup>

我最初尝试过，但没有用 b/c 我输入了 'netstandard20' 而不是 'netstandard2.0' ....

哦，现在可以使用了，感谢大家的帮助。

ConfigurationManager 存在于 System.Configuration.ConfigurationManager 和 System.Configuration 中

ConfigurationManager exists in both System.Configuration.ConfigurationManager and in System.Configuration
