Binding Native Library No Longer Works

I've been working on a project since November, and it has been building fine until yesterday when I upgrade Visual Studio 2017 and upgraded the Mac to Visual Studio for Mac.

Now, it cannot find any of the references from the native library assembly in my UI project.

I get this error in the iOS UI project for each Namespace the native library project.
Error CS0246 The type or namespace name 'The Namespace Name etc...' could not be found (are you missing a using directive or an assembly reference?)

I can download the November build and use the caches that are on the Mac and the bin folder from the old build and it still works (runs on the Mac iPhone simulator). I cannot however clean the solution and rebuild. Since I upgraded, Intellisense has the red lines under all references to the native library namespaces.

Everything was working before, and I did not make any changes except inside my UI ViewController. The only changes are Visual Studio for PC and Mac.

My info.plist is set to build none.
My .a file build action is set correctly.

It looks like there are some similar issues in Bugzilla that have been closed or are still open. Is this a known issue?
