nuget 无法安装、更新或删除包 "same key has already been added."

Question

我无法在我们的解决方案之一上安装/升级/卸载任何 nuget 包。据我所知，这与 PCL 无关，因为它在两台机器上是相同的。解决方案中的三个项目之一可以使用 nuget 更新，另外两个(较大的项目)失败并显示以下堆栈跟踪。

有没有人见过这个或知道如何解决它？我们在 packages.config 中没有重复的包名称，清除它们，文件夹和引用没有帮助，我们在管理员模式下运行并更新它。

虽然与这些 [1]、[2] 和 [3] 类似，但堆栈跟踪不匹配并且所有修复均无效。

[1] Visual Studio 2015, Nuget and “same key has already been added.”

[2] An item with the same key has already been added while Installing nuget package

[3] installing nuget package "same key has already been added."

为了帮助其他遇到此问题的人，我发现这是因为我们的 dependentAssembly 在我们的 web.config 中没有 bindingRedirect(当使用 uCommerce 重定向他们的 dll 引用时会发生这种情况)例如

<dependentAssembly>
    <assemblyIdentity name="Infralution.Licensing" publicKeyToken="3e7e8e3744a5c13f" />
    <codeBase version="4.7.1.0" href="bin\ucommerce\Infralution.Licensing.dll" />
</dependentAssembly>

我已经检查了 nuget 更改日志并且有一个 similar thing reported here所以将等待最新版本，看看是否可以解决它。

它似乎也有一个别名引用的问题，我将报告它
