Question

我开始在C＃项目中使用HttpClient.GetAsync（）。无论何时调用此方法，它都会爆炸，无法找到Newtonsoft.Json。

为了获得该方法，我安装了Microsoft.AspNet.WebApi.Client nuget软件包，版本5.2.3。这列出了对Newtonsoft.Json，v 6或更高版本的依赖。已安装8.0.3版。

我做错了什么？ nuget包应该管理它自己的依赖项？为什么nuget为系统DLL？完整的错误如下......

System.IO.FileLoadException was unhandled by user code
  FileName=Newtonsoft.Json, Version=6.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed
  FusionLog=WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

尝试将程序集绑定重定向添加到app / web.config

<configuration>
 <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-8.0.0.0" newVersion="8.0.0.0" />
      </dependentAssembly>
    </assemblyBinding>
 </runtime>
</configuration>

HttpClient.GetAsync（）抛出FileLoadException，找不到Newtonsoft.JsonNET
