I have a .net standard 2.0 dll (Drivers.CommunicationLocal) which is referencing SerialPort class. When I try to use this from a .Net 4.6.1 console app or a xUnit (.net core 2.0) on windows 10, I get the following exception. Using it from UWP app works fine.

System.PlatformNotSupportedException: System.IO.Ports is currently only supported on Windows.
at System.IO.Ports.SerialPort..ctor(String portName, Int32 baudRate, Parity parity, Int32 dataBits)
at Drivers.CommunicationLocal.CommunicationLayerSerialPortLocal..ctor(SettingSerialPortLocal settings) in C:\Users\abc\Documents\Visual Studio 2017\Projects\experiment\senna\src\Drivers.CommunicationLocal\CommunicationLayerSerialPortLocal.cs:line 24

I am using nuget package System.IO.Ports.
