无法加载文件或程序集“Newtonsoft.Json, Version=7.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed"或其依赖项之一 [英] Could not load file or assembly 'Newtonsoft.Json, Version=7.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed' or one of its dependencies

问题描述

这个错误让我发疯.

我在名为 BaseServices 的类库之一中安装了 SendGrid NuGet 包，它依赖于 Newtonsoft.Json v7.0.1，所以它会在我的包文件夹中安装它并引用它.

I installed the SendGrid NuGet package in one of my class libraries named BaseServices, which has a dependency on Newtonsoft.Json v7.0.1, so it installs that in my packages folder and references that.

在类库中，我有这个绑定重定向:

In the class library, I have this binding redirect:

<dependentAssembly>
    <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-7.0.0.0" newVersion="7.0.0.0" />
</dependentAssembly>

在 ASP.NET MVC 应用程序的 web.config 中，即使用我的类库的客户端应用程序，我有一个程序集绑定重定向，版本低于 v6 以指向 Newtonsoft.Json 像这样的库:

In the web.config of the ASP.NET MVC application, i.e. the client application that uses my class library, I have an assembly binding redirect for versions less than v6 to point to v6 of the Newtonsoft.Json library like so:

<dependentAssembly>
 <assemblyIdentity name="Newtonsoft.Json" culture="neutral"
              publicKeyToken="30ad4fe6b2a6aeed" />
  <bindingRedirect oldVersion="0.0.0.0-6.0.0.0" newVersion="6.0.0.0" />
</dependentAssembly>

当我运行 BaseServices 库中的电子邮件发送代码时，我收到此错误:

When I run my email sending code that is in the BaseServices library, I get this error:
