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

没有一个答案,包括选中的那个都不适合我。

解决办法要简单得多。我首先从BUS层删除了引用。然后从项目中删除dll(以确保它已经消失),然后重新安装JSON。NET从nuget包。而且,棘手的部分是,“把它关掉再打开”。

我刚刚重启visual studio,它工作了!

因此,如果您尝试了所有可能的方法,但仍然不能解决问题,请尝试关闭visual studio并再次打开,这可能会有所帮助。

如果这些都不行,请检查这个答案:

https://stackoverflow.com/a/12011221/150370

(TL;DR:从配置文件中的配置标签中删除xml命名空间。否则绑定重定向将被忽略)

我得到了dotnet核心同样的问题,并设法通过清除NuGet缓存来修复它。

打开powershell,输入以下命令。

dotnet nuget locals all --clear

然后我关闭Visual Studio,再次打开它,并在包管理器控制台输入以下命令:

Update-Package

NuGet现在应该恢复所有的包,并再次填充NuGet缓存。

在那之后,我能够在Linux容器中构建并启动我的dotnet核心webapi。

安装或更新Newtonsoft后,web会发生一些变化。配置和那些必须移动到网络。在live/prod环境中,它们是必需的,这取决于使用的版本。

我们也有同样的问题,因为我们一直在使用发布自动化和wen。配置文件将不会在prod/staging环境中被覆盖。所以web必须手动更改配置文件。

解决我这个问题的办法是

goto引用->右键单击Newtonsoft。goto属性,检查版本

同样的版本应该在
