Question

我无法在Visual Studio 2013中构建解决方案。

这是在我将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。它也引用了JSON.NET，我想，也许是动态的？

完整错误

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]

我在我的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>

我在.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>

构建输出

Answer 1

在您的csproj文件中，您会注意到Newtonsoft.Json有2个条目。删除以下条目：

<Reference Include="Newtonsoft.Json">
    <HintPath>..\packages\Newtonsoft.Json.5.0.6\lib\net45\Newtonsoft.Json.dll</HintPath>
</Reference>

Answer 2

您可以反映owin并查看参考文献中的内容。如果它查找特定版本，则会遇到麻烦，但如果没有，只需将您想要的版本与owin一起放入应用程序bin中，并希望签名匹配。还要记住，有GAC。所以，你有实验的空间

Answer 3

合并后，我遇到了几乎相同的问题。原来在csproj文件中向左合并了两个对Newtonsoft.Json的引用。项目中有DLL，NuGet包管理器中只有一个版本，但是csproj引用了Newtonsoft.Jason 5.0.6和5.0.8

我在notepad ++中编辑了csproj，并删除了有问题的参考文献，等等。解决了构建错误

'Newtonsoft.Json ...'存在于'Blend \ Newtonsoft.Json.dll'和'Solution \ packages \ ... \中
