System.Net.Http 4.2 与 .NET 4.7

Question

如何消除构建输出中的警告？

解决方案中的所有项目都以 .NET Framework 4.7 为目标。这是一个巨大的解决方案，包含 50 多个我不熟悉的项目。不确定是什么更改导致了这些警告，可能是添加了 System.Web.Http.SelfHost.dll 程序集。无论程序集重定向绑定如何，构建输出都会溢出。另外，我正在使用 Visual Studio 2019（看起来像源 dll 供参考 System.Net.Http v4.2）。

(ResolveAssemblyReferences target) -> 
Found conflicts between different versions of "System.Net.Http" that could not be resolved.
There was a conflict between "System.Net.Http, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" and "System.Net.Http, Version=4.2.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a".
     "System.Net.Http, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" was chosen because it was primary and "System.Net.Http, Version=4.2.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" was not.

    C:\dev\Build\System.Web.Http.SelfHost.dll
    C:\dev\Build\netstandard.dll

在我尝试之后，在构建输出中添加了其他引用，例如：

Org.Lib.Workflow, Version=1.0.0.0, Culture=neutral, processorArchitecture=MSIL
System.Web.Http.SelfHost, Version=5.2.7.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL

也尝试了投票最高的版本 (newVersion="4.0.0.0")，但没有任何改变

根据建议，由于我需要使用 4.2 版，我已将相应的版本复制到存储库并添加了对它的引用。
