The QrCode library is a port of https://github.com/nayuki/QR-Code-generator java implementation.

#Using QRCodeGenerator Library

using QrCodeGenerator;
using System.Drawing;

string text = "Hello, world!";
Ecc errCorLvl = Ecc.Low;

QrCode qr = QrCode.EncodeText(text, errCorLvl);

Bitmap img = qr.ToImage(scale: 10, border: 4) //Get Bitmap

string svg = qr.ToSvgString(border: 4); //or a svg xml string

Visit QrCodeGenerator.ConsoleTests for more examples

#Using MVC helper

• Add new keys to AppSettings

"qrCode": {
  "ecc": "Low",
  "format": "Svg"
}

Format can be Svg or Png.

Ecc can be Low, Medium, Quartitle or High.

• Register the service on startup.cs

using QrCodeGenerator.Mvc;

services.AddQrCodeTagHelper(Configuration);

• Add TagHelper on _ViewImports.cshtml

@addTagHelper *, QrCodeGenerator.Mvc

• Use the TagHelper when necessary

<qrcode data="@Model.QrCodeContent" scale="10" border="5"/>

The parameter scale must be passed if Png is the defined format.
