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

Question

我无法在Visual Studio 2013中构建解决方案.

这恰好发生在我将JSON.NET包更新到6.0.1之后.在此之前,它就像一个魅力.

有任何想法吗？

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>

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

您可以反思owin并查看它在参考文献中寻找什么。如果它寻找特定版本，你就会遇到麻烦，但如果没有，只需将你想要的版本与应用程序 bin 一起放入应用程序 bin 中owin，并希望签名匹配。另请记住，还有 GAC。所以，你有实验的空间
