Hello since the last Xamarin updatewe get this error.
你好，自从上次Xamarin update我们得到这个error。

In my case it was a bit different, I couldn't find monoandroid folder in
就我而言，它有点不同，我找不到 monoandroid 文件夹

So on further I searched and found it in
因此，我进一步搜索并在

This might be the case with someone else.

These errors are not due to a problem with the solution or the references. They are a by-product of other changes that seem to confuse tools like ReSharper. At least this is correct in my case, my solution still compiles and functions without manually referencing any Reference Assemblies.
这些错误不是由解决方案或参考资料的问题引起的。它们是其他更改的副产品，这些更改似乎混淆了诸如ReSharper. 至少在我的情况下这是正确的，我的解决方案仍然可以编译和运行，而无需手动引用任何参考程序集。
There is a Xamarin bug report for this but they determined this to be an external issue with ReSharperas per my experience.
有一个 Xamarin 错误报告，但ReSharper根据我的经验，他们确定这是一个外部问题。
Rather than manually adding references to the project you can also tell ReSharper to simply ignore the errors by opening:
除了手动添加对项目的引用之外，您还可以通过打开告诉 ReSharper 简单地忽略错误：
ReSharper -> Windows -> Solution Errors
And then ignoring the issues here.
然后忽略这里的问题。
