WiFiDriver

RTL8812AU userspace driver.
Yes. It's real. Userspace wifi driver with monitoring support.

How to use

1. Install WinUSB driver for you adapter via Zadig
2. Install nuget package to your project
3. Write some code:

internal class Program
{
    static void Main(string[] args)
    {
        Console.WriteLine("Hello, World!");

        var loggerFactory = LoggerFactory.Create(builder =>
            builder
                .SetMinimumLevel(LogLevel.Trace)
                .AddConsole());

        using var driver = new WiFiDriver(loggerFactory);
        var devices = driver.GetUsbDevices();
        var device = devices.First();

        var rtlDevice = driver.CreateRtlDevice(device);

        rtlDevice.Init(
            PacketProcessor,
            new()
            {
                ChannelWidth = ChannelWidth.CHANNEL_WIDTH_20,
                ChannelOffset = 0,
                Channel = 140,
                //Channel = 36
            });

        Console.ReadLine();
        Console.WriteLine("End");
    }

    private static Task PacketProcessor(ParsedRadioPacket packet)
    {
        Console.WriteLine($"Packet received. Data len: {packet.Data.Length}");

        return Task.CompletedTask;
    }
}

4. Use (Packet.Net)[https://github.com/dotpcap/packetnet] for parsing frames data(not tested but have to work)
