搜索后我尝试过的事情：

1. 在Web.Config中，对旧版本进行绑定：

   <dependentAssembly>
   <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" />
   <bindingRedirect oldVersion="0.0.0.0-6.0.0.0" newVersion="6.0.1.0" />
   

2. 编辑我的.csproj文件，以确保只有一个Newtonsoft参考

        <Reference Include="Newtonsoft.Json, Version=6.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed, processorArchitecture=MSIL">
       <HintPath>..\packages\Newtonsoft.Json.6.0.1\lib\net45\Newtonsoft.Json.dll</HintPath>
       <SpecificVersion>False</SpecificVersion>
       <Private>True</Private>
    </Reference>

1. 在我的计算机上搜索每个Newtonsoft.Json.dll并删除每个非6.0.1版本并删除我的temp文件夹的内容

2. 在nuget Manager控制台中修复/重新安装软件包

它可以成功构建，但是在转到站点时出现错误。

编辑

好的，因此我尝试像每个nuget软件包一样重新安装，似乎已添加回4.5版本的newtonsoft.json.dll，但我遇到了相同的错误。我项目的目标框架是.NET
4.5.1，这是我现在得到的堆栈跟踪：

“ /”应用程序中的服务器错误。

无法加载文件或程序集Newtonsoft.Json或其依赖项之一。找到的程序集的清单定义与程序集引用不匹配。（从HRESULT异常：0x80131040）

说明：执行当前Web请求期间发生未处理的异常。请查看堆栈跟踪以获取有关错误及其在代码中起源的更多信息。

异常详细信息：System.IO.FileLoadException无法加载文件或程序集Newtonsoft.Json或其依赖项之一。找到的程序集的清单定义与程序集引用不匹配。（从HRESULT异常：0x80131040）

源错误：

当前Web请求的执行期间生成了未处理的异常。可以使用下面的异常堆栈跟踪来标识有关异常的来源和位置的信息。

程序集加载跟踪：以下信息有助于确定为什么Newtonsoft.Json无法加载程序集。
