title: Accessing the SerialPort class using .Net Core 3.0
body: <p>I'm starting a new .NET Core 3.0 project in which I need to access the System.IO.Ports.SerialPort class. The documentation I'm reading on the class shows that it is applicable to .NET Core 3 ( see the bottom of <a href="https://docs.microsoft.com/en-us/dotnet/api/system.io.ports.serialport?view=netcore-3.0" rel="noreferrer">https://docs.microsoft.com/en-us/dotnet/api/system.io.ports.serialport?view=netcore-3.0</a> ). However when I add a using statement to my class it isn't able to resolve System.IO.Ports. Is there some additional step that needs to be done to reference the SerialPort class for a .NET Core 3.0 program running on the Windows desktop?</p>
