I am not sure about MonoGame v 3.7.0. But v 3.7.1 of MonoGame works with Visual Studio 2017 for Mac (v 7.8.4).
To clarify, Visual Studio Code is a different IDE and not the right one for MonoGame.
Additionally, Visual Studio 2019 for Mac (v 8.0.9) is the latest version of Visual Studio for Mac and does not support MonoGame v 3.7.1.
