我无法在我们的某个解决方案上安装/升级/卸载任何nuget包。这与PCL无关，因为它在两台机器上都是一样的。解决方案中的三个项目之一可以使用nuget进行更新，其他两个（较大的项目）可以使用下面的堆栈跟踪进行更新。
有没有人看过这个或知道如何解决它？我们在packages.config中没有重复的软件包名称，清除它们，文件夹和引用没有帮助，我们正在管理模式下运行并将其更新为最新版本。
虽然类似于这些[1]，[2]和[3]，但堆栈跟踪不匹配，并且没有任何修复工作。
[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."

为了帮助其他人解决这个问题，我发现这是因为我们的slaveAssembly在我们的web.config中没有绑定重定向（这种情况发生在使用uCommerce重定向他们的dll引用时），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similar thing reported here因此会等待最新版本，看看是否能解决它。
它似乎也存在我所报告的别名引用的问题
