Repro:

• Open tests/tests.sln in VSMac.
• Build the framework-test project.
• Open the FrameworkTests.cs file.

Any API used from the bindings-framework-test project are squiggly red, and intellisense doesn't work:

This is something we have to fix in our msbuild logic somewhere.

Note that building the solution actually works, this just affects editing experience in the IDE (intellisense doesn't work).

A potential workaround is to build the binding project separately, and then just reference the binding assembly (.dll) in the main project instead.
