Hello,
You can use the LEADTOOLS SDK for this.
private void WriteBarcode(string value, string imageFileName)
{
RasterCodecs codecs = new RasterCodecs();
RasterImage image = RasterImage.Create(2550, 3300, 1, 300, RasterColor.White);

BarcodeWriter writer = new BarcodeEngine().Writer;

// Create the barcode data
QRBarcodeData barcode = BarcodeData.CreateDefaultBarcodeData(BarcodeSymbology.QR) as QRBarcodeData;
barcode.Value = value;

// We will use the alignment to position the barcodes, so use all of the image
barcode.Bounds = new LeadRect(0, 0, image.ImageWidth, image.ImageHeight);

// Set the write options
QRBarcodeWriteOptions options = new QRBarcodeWriteOptions();
options.GroupNumber = 0;
options.GroupTotal = 0;
options.XModule = 30;
options.ECCLevel = QRBarcodeECCLevel.LevelL;

// Write it
Console.WriteLine("Writing barcode data: {1}", value);
writer.WriteBarcode(image, barcode, options);

// save to disk
codecs.Save(image, imageFileName, RasterImageFormat.CcittGroup4, 1);
}
We have NuGet packages available for .NET Core for this functionality.
https://www.leadtools.com/downloads/nuget?nuget_package=Leadtools.Barcode
There's also a .NET Core tutorial showing how to create a barcode and save it to a file on disk.

Try Spire.Barcode for .NET, it works for .NET code.
using Spire.Barcode;
using System.Drawing;

namespace QRCode
{
    class Program
    {
        static void Main(string[] args)
        {
            BarcodeSettings settings = new BarcodeSettings();
            settings.Type = BarCodeType.QRCode;

            settings.Data = "Hello 123456789";
            settings.Data2D = "Hello 123456789";
            settings.QRCodeDataMode = QRCodeDataMode.AlphaNumber;
            settings.X = 1.0f;
            settings.QRCodeECL = QRCodeECL.H;

            BarCodeGenerator generator = new BarCodeGenerator(settings);
            Image image = generator.GenerateImage();
            image.Save("QRCode.png");
        }
    }
}

Hi,
Try this.
QRCodeGenerator _qrCode = new QRCodeGenerator();
QRCodeData _qrCodeData = _qrCode.CreateQrCode("QR code text",QRCodeGenerator.ECCLevel.Q);
QRCode qrCode = new QRCode(_qrCodeData);
Bitmap qrCodeImage = qrCode.GetGraphic(20);
using (MemoryStream stream = new MemoryStream())
{
     qrCodeImage.Save(stream, System.Drawing.Imaging.ImageFormat.Png);
     return stream.ToArray();
}
