Trying to run a create a class from a .net standard dll that uses Registry

import clr
clr.AddReference("Demant.PlatformInternal.Communication")

from Demant.PlatformInternal.Communication.Cdc import CdcStandardCommunication
com = CdcStandardCommunication(0x3001)
com.connect(0)

using System.Collections.Generic;
using System.Linq;
using Demant.CommonTools.Collections;
using Demant.CommonTools.Texts;
using Demant.PlatformInternal.Communication.External.Registry;
using Demant.PlatformInternal.Communication.External.Serial.SerialPortStream;

namespace Demant.PlatformInternal.Communication.Tools
{
  public class SerialDeviceLocator
  {
    private readonly IRegistryKey usbRootKey = RegistryRoot.OpenSubKey(@"SYSTEM\CurrentControlSet\Enum\Usb");
    private string[] portNames;
    private readonly string vidPidName;
    private readonly string vidPidMiName;

    public SerialDeviceLocator(int pid, int interfaceNumber = 0)
    {
      vidPidName = $"VID_0EEA&PID_{pid:X4}";
      vidPidMiName = $"VID_0EEA&PID_{pid:X4}&MI_{interfaceNumber:X2}";
    }

I have place the python script in the folder with the out put of the dll build :

It tells you what's going on:

System.PlatformNotSupportedException: Registry is not supported on this platform.

It's a known issue in the library: dotnet/runtime#27033 (comment)
