问题
I am running Visual Studio 2019 preview and I have the Android preview sdk installed (9.0.99) But when I try to build a xamarin forms project with a library set to netstandard 2.1. I still het a compatibiliteit error with monodroid. What am I missing? Been searching quite a bit and found something about a mono 2019-06 I believe, but no info on how to get it.

This github document shows that Xamarin Android support NS2.1 since version 10:
So if you use lastest nightly version, you should be able to use it.
