【问题描述】：
我无法在 Visual Studio 2013 中构建解决方案。
这只是在我将 JSON.NET 包更新到 6.0.1 之后发生的。在此之前，它就像一个魅力。
有什么想法吗？
PS：这可能与 OWIN 有关。我认为它也引用了 JSON.NET，也许是动态的？
完全错误
Error 11 The type 'Newtonsoft.Json.Linq.JObject' exists in both
'c:\Program Files (x86)\Microsoft Visual Studio 12.0\Blend\Newtonsoft.Json.dll' and
'c:\Users\Me\Desktop\Solutions\[Project]\packages\Newtonsoft.Json.6.0.1\lib\net45\Newtonsoft.Json.dll'
C:\Users\Me\Desktop\Solutions\[Project]\TrendPin\App_Start\Startup.Auth.cs 48 21 [Project]
我的 Web.Config 中有这个
<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>
我的 .csproj 中有这个
<Reference Include="Newtonsoft.Json, Version=6.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed, processorArchitecture=MSIL">
<SpecificVersion>False</SpecificVersion>
<HintPath>..\packages\Newtonsoft.Json.6.0.1\lib\net45\Newtonsoft.Json.dll</HintPath>
</Reference>

【问题讨论】：
-
转到引用，删除旧的并手动将新的添加到包文件夹中的正确 dll 中。设置复制=真。您必须小心更新内容。看起来您引用了两个版本。您可能只需要删除一个
-
OWIN 实际上引用了旧版本，据我所知。我删除了 OWIN，它起作用了。但我希望他们一起工作。 （我也更新了问题）
-
您可以反映
owin并查看它在参考中寻找什么。如果它寻找特定版本，你有麻烦，但如果没有，只需将你想要的版本与 owin 一起放入 bin 并希望签名匹配。还要记住，还有 GAC。所以，你还有实验的空间 -
请把它写成答案，我会接受。先生，你解释得很好。
