搜索后我尝试过的事情:

in Web.Config put a binding on the old version: <dependentAssembly> <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" /> <bindingRedirect oldVersion="0.0.0.0-6.0.0.0" newVersion="6.0.1.0" /> </dependentAssembly> Edit my .csproj file to make sure there is only one Newtonsoft reference <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> Search my computer for every Newtonsoft.Json.dll and delete every non 6.0.1 version and delete the contents of my temp folder Repair/Reinstall the package in nuget manager console

它成功构建,但在访问站点时得到错误。

EDIT

好吧,然后我尝试重新安装每个nuget包,它似乎已经添加了4.5版本的newtonsoft.json.dll,但我得到了同样的错误。我的项目的目标框架是。net 4.5.1,这里是我现在得到的堆栈跟踪:

当前回答

好吧,所以我想要做的事情是把我的答案添加到这个长列表中,而不是创建一个重复的问题……

如果你在2019年使用。net Core 3.0(目前是预览版),解决方案是确保所有项目都针对相同的。net Core版本(在我的情况下是3.0)。我想我在解决方案中有一个项目是针对2.1的,其余的是2.2的,所以我可能会坚持使用2.2…

我甚至没有牛顿软体。Json安装在任何项目中,自然地添加它并不能解决这个问题。

如果你的解决方案中有。net标准类库或w/e,它们不需要在同一个版本上,尽管它们可能应该是你可以使用的最新版本。例如,我的. net标准类库是在2.2上的,因为还没有. net标准3.0。

其他回答

经过几个小时的挣扎…我做了以下事情:

. config

<runtime>

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

    <dependentAssembly>
      <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" />
      <bindingRedirect oldVersion="0.0.0.0-12.0.0.0" newVersion="12.0.0.0" />
    </dependentAssembly>

    <!-- other assemblies... -->

  </assemblyBinding>
</runtime>

输入正确的newVersion和oldVersion编号的关键是打开项目的引用,找到包,进入它的属性或单击alt + enter

你会发现一节版本,在我的情况下是12.0.0.0,而它实际上是12.0.3,当探索与管理NuGet。

所以您需要从引用属性中选择包的版本(在我的例子中是12.0.0.0)

最后,清理并重新构建项目(您可能希望之前删除bin和obj文件夹)。

你可能会面临其他包的依赖问题,我做的所有,他们工作。

从工具>>NuGet包管理>>管理包解决方案 更新Newtonsoft。最新版本的所有解决方案的Json

我不知道为什么,但在我的情况下,即使我从项目中删除bin文件夹,当我构建项目时,它会复制旧版本的newtonsoft。json,我复制了新版本的dll从包文件夹和它解决现在。

为了解决这个问题,我通过运行以下命令并检查结果来确保我所有的项目都使用了相同的版本:

update-package Newtonsoft.Json -reinstall

最后,我从我的web.config删除了以下内容:

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

如果你想确保所有的牛顿软。Json包是相同的版本,你可以这样指定版本:

update-package Newtonsoft.Json -version 6.0.0 -reinstall

注意:要在Visual Studio中打开PMC,请单击工具-> Nuget包管理器->包管理器控制台。谢谢@Rose !

在确保我的计算机在所有位置都有相同的版本并且我的项目都指向相同的参考路径之后,我尝试了以下操作。我还确保旧版本的绑定是他们的,并绑定到我拥有的当前版本的dll。

我在一个有严格框架的环境中工作,框架团队经常用不同的dll来打乱版本控制。

我解决这个问题的方法是在visual studio(2013)中运行包管理器控制台。从那里我运行以下命令:

update-package Newtonsoft.Json -reinstall

紧随其后的是

update-package Newtonsoft.Json

这遍历并更新了我所有的配置文件和相关的项目文件。强制它们都到同一个dll版本。它最初是4.5版本,然后再次更新以获得最新版本。
