visual studio2017 无法添加引用 未能加载包ReferenceManagerPackage not such interface support 解决方法

安装完visual studio 2017 后添加引用总是提示 未能加载包ReferenceManagerPackage， 这个问题困扰了两天，直到在网上看到了下面这一段

I just got this error after installation of Visual Studio 2017.

The solution was as follows.

1. Launch Developer Command Prompt for VS 2017
2. CD C:\Program Files\Microsoft Visual Studio\2017\Community\Common7\IDE\PublicAssemblies
3. Run gacutil -i Microsoft.VisualStudio.Shell.Interop.11.0.dll

You should now see

Microsoft (R) .NET Global Assembly Cache Utility.  Version 4.0.30319.0

Assembly successfully added to the cache

Restart Visual Studio and hopefully all will be well and you can add references.

The file C:\Users\USER\AppData\Roaming\Microsoft\VisualStudio\15.0_cc9cc69a\ActivityLog.xml is useful for debugging any other assemblies that may be causing the issue. Annoyingly it's very tempting to click No when asked never to see the error message again, which will suppress the error and this path so I thought I'd post it here for reference.
