SerialPorts with .NET Standard 2.1

Unity Engine
1

Hi,
Sorry if this is in the wrong place.

I’m trying to get serial ports working with .NET Standard 2.1. It works with .NET Framework but ideally, I don’t want to use this if I don’t have to.

I understand that .NET 2.0 was the last version to have serial support directly and now it’s available via the NuGet package NuGet Gallery | System.IO.Ports 8.0.0
However, I’m unable to get this to work.

Using the .NET Standard 2.0 gets me the following error:

Exception: System.IO.Ports is currently only supported on Windows. StackTrace:   at System.IO.Ports.SerialPort..ctor (System.String portName, System.Int32 baudRate) [0x0000b] in <c6d1344d4a914d5aba16ee2e4d4a5e71>:0
  at (wrapper remoting-invoke-with-check) System.IO.Ports.SerialPort..ctor(string,int)

I’m wondering if it’s possible to use the mono implementation? I tried to include it using a csc.rsp but no luck.

Any help is greatly appreciated.

EDIT: I actually managed to get this to work in the end.
When opening the NuGet package I was using the netstandard2.0 dll’s from the lib directory but I noticed there is a runtime directory with the same netstandard2.0 directory and dll’s. I used this with my editor set to .NET Standard 2.1 and it works.
I hope this helps those in the future.

Hi, I received the same error message - only supported on windows even though I have NET standard 2.1. And seems my OVR camera rigs are missing too. Do you know any alternative in solving this issue?

Still looking for a solution for this.
