## What it is
ZXing.Net is a .NET port of the Java ZXing barcode library that decodes and generates barcodes such as QR Code, Data Matrix, Aztec, EAN, UPC, and PDF-417 from images. It ships assemblies for a wide range of .NET platforms including .NET Framework, .NET Core, Unity, Xamarin, and bindings to imaging libraries like SkiaSharp and ImageSharp.

## Use cases
- scan qr codes from images in a .net app
- generate barcode images in c#
- decode pdf417 from a camera feed
- read ean/upc codes from product photos
- add barcode scanning to a unity app
- generate data matrix codes for labels

## When to choose
- you need barcode reading or writing in any .NET-based project
- you need support for many barcode symbologies across many .NET runtimes
- you want bindings to common imaging libraries like SkiaSharp, ImageSharp, or OpenCVSharp

## When to avoid
- you need a non-.NET language like Java, JavaScript, or Python
- you need real-time high-throughput industrial barcode scanning with hardware acceleration
- you only target platforms with obsolete support like Silverlight or Windows Phone

## Facets
- artifact type: library
