c# - 'Newtonsoft.Json.. .' exists in both ' Blend\Newtonsoft.Json.dll' 和 'Solution\packages\...\

Question

我无法在 Visual Studio 2013 中构建解决方案。

这发生在我将我的 JSON.NET 包更新到 6.0.1 之后。在此之前，它就像一个魅力。

有什么想法吗？

PS:这可能是关于 OWIN 的。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>

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>
