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

Question

我开始在c＃project中使用httpclient.getAsync（）。每当调用此方法时，它会炸毁，无法找到newtonsoft.json。

要获取方法，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或更高的依赖性。安装了8.0.3版。

我在做什么错？Nuget软件包应该管理自己的依赖关系？为什么要使用系统dll？完整错误如下...

尝试将汇编绑定重定向添加到您的应用/web.config

<configuration>
 <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
