After making a fresh new Xamarin Forms project using VS 2019 i go straight into manage nuget packages and try to install Xamarin.Firebase.core to my PCL and android project and straight away i get the error that the it has rolled back and the package is not compatible with netstandard2.0 and it supports monoandroid90 is whatever it is called.
can anybody tell what is going on and how can i fix this?
