无法加载文件或程序集"Newtonsoft.Json，版本= 7.0.0.0，区域性=中性，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

这个错误使我发疯.

我在名为 BaseServices 的一个类库中安装了 SendGrid NuGet软件包，该软件包依赖于 Newtonsoft.Json v7.0.1 ，因此它将其安装在我的packages文件夹中并对其进行引用.

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，我具有此绑定重定向:

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(即使用我的类库的客户端应用程序)的web.config中，对于小于v6的版本，我具有程序集绑定重定向，以指向 Newtonsoft.Json 库如下:

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>

运行 BaseServices 库中的电子邮件发送代码时，出现以下错误:

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