I'm seeing exactly the same issue, only difference in my case is it's a Xamarin.Mac library referencing a .NET Standard library.
Prior to updating I was able to build the library without any errors, now every reference in the Xamarin.Mac library to an object in the .NET Standard library returns the following error:
Error CS0012: The type 'Object' is defined in an assembly that is not referenced. You must add a reference to assembly 'netstandard, Version=2.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'. (CS0012)
There's been no changes to the project references or code, and I've tried cleaning all the projects and deleted all the 'obj' and 'bin' folders, but the result is the same.
The newest 8.2 release of Visual Studio for Mac also has the same issue. Here's the full version information from my 'About window:

Issue moved from dotnet/standard#1269

I'm not sure where this issue should be reported, but since it is somewhat related to dotnet/standard#542, I figured I'd start here. This week, some of my team installed the latest updates in Visual Studio for Mac and after doing so they now encounter errors when trying to build. I've created a simple reproduction at https://github.com/tstuts/net-standard-test using a Xamarin.Mac app and a .NET Standard library.
