我看到一些非常奇怪的行为，我无法纠正与Newtonsoft.Json.dll的引用相关。我有一个样本解决方案，其中包含以下项目：
在JsonProblem.Core和JsonProblem.Web中，我添加了“Microsoft ASP.NET Web API 2.2”NuGet包。在JsonProblem.Core中，我创建了一个web api。如果我构建JsonProblem.Core并从JsonProblem.Web运行一个页面，一切都按预期工作。
现在如果我构建JsonProblem.CauseProblem并尝试在JsonProblem.Web中查看页面，我会收到以下错误。
无法加载文件或程序集“Newtonsoft.Json”或其中一个 依赖。定位程序集的清单定义没有 匹配程序集引用。 （HRESULT异常：0x80131040）
如果我重建JsonProblem.Core，则错误消失。再次，如果我构建JsonProblem.CauseProblem后不构建JsonProblem.Core（即使JsonProblem.CauseProblem依赖于JsonProblem.Core）我得到错误。不知何故，JsonProblem.CauseProblem的构建导致Newtonsoft.Json版本4.5.11被复制到JsonProblem.Web bin目录，覆盖版本6.0.3。我很确定我正确设置了绑定重定向，因为我在JsonProblem.Web web.config和JsonProblem.Core和JsonProblem.CauseProblem的app.config文件中有以下内容：
<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>
所以我对这种奇怪行为的原因感到茫然。我在2个项目中复制了它。当我构建JsonProblem.CauseProblem时，似乎忽略了绑定重定向。我可以解决它，但我担心无论哪种错误或功能导致此行为可能会改变后台中可能导致问题的其他引用。

我有与上述问题描述完全相同的行为，除了当我重建我的类库（即JsonProblem.Core）时，它会引入Newtonsoft.dll 4.5.11，即使这个类库没有直接引用或Nuget包表示对NewtonSoft的引用。
在可能被视为Visual Studio 2015错误的情况下，类库重建将无形引用的DLL复制到引用项目bin文件夹（当前未构建），在引用项目中覆盖DLL，破坏它们。
IOW，例如，构建项目Y（引用JsonProblem.Core），显然是成功的。构建项目X（引用JsonProblem.Core），打破项目Y.构建项目Y，现在打破项目X.无限循环：while（sane）{build（）; }
就我而言，我在这个库中引用的唯一的第三方库是Gibraltar.Agent和Gibraltar.Agent.Web.Mvc（它报告没有依赖于NewtonSoft。在项目参考中右键单击这些并选择＆＃ 34;找到依赖于这个模块的代码＆＃34;显示我不需要引用第二个。
我在Nuget中卸载了Gibraltar.Agent.Web.Mvc，所有问题都消失了。两天的DLL地狱心痛已经结束。

您可能在这里处理了一些不同的场景。我给你的建议是使用fuslogvw工具向你展示它试图加载的dll，以及它在哪里寻找它。由于装配绑定重定向在表面上看起来正确，因此可能存在另一个在此处被屏蔽的依赖性问题。 fuslogvw工具只允许您查看程序集绑定行为以及发生了什么。拥有装配绑定问题真的很棒。
