So i'm trying to read arduino serial from c#, but it shows me the folowing exeption when i try to open the port:
System.PlatformNotSupportedException: 'System.IO.Ports is currently only supported on Windows
I am currently using windows 11.
Also i tried setting the target OS to windows in the .csproj file.
How did you set the target OS?
Maybe it is possible to create another type of project (WPF, Forms).

What do you have in your project file for TargetFramework?
You should have something like this:
<TargetFramework>net6.0-windows</TargetFramework>
I set the target framework just like that
<TargetFramework>net6.0-windows</TargetFramework>
oh and i tried to create a nother one, but it didn't work. Maybe i'll try it on a nother computer, and see if it works.
Have you added the System.IO.Ports NuGet package to your project?
This .NET 6 C# console project code compiles and runs OK for me - though I don't have any serial ports on my machine.
namespace SerPortsTest
{
internal class Program
{
static void Main(string[] args)
{
var ports = System.IO.Ports.SerialPort.GetPortNames();
}
}
}

I have exactly the same (only at runtime - not when debugging), when targeting net8.0-windows
I've found the way to solve the exception,using the folder "runtimes\win\lib\net6.0",then everything is ok.

I got the same exception when using the system.io.ports 9.0.x version on .net 6.0 on windows
I changed the system.io.ports package to version 8.0.0, it worked!!
