Counts unlabeled, assigned, unassigned, milestoned, demilestoned, locked, unlocked over the last 12 months. These are issue and pull request events that require triage or write permission. Commits and code review are not counted. labeled and renamed are excluded because GitHub issue forms record the issue author as the actor. Figures from October 18, 2026. This count is not comparable across projects: each project's automation decides which of these events a person emits. How this is counted.

How this project is maintained

100% of open issues come from outside the core team, so the backlog reflects real-world use rather than internal planning. Three people close 84% of everything that gets resolved.

Detailed Description

ZXing.Net is a barcode encoding and decoding library for .NET that reads and generates multiple barcode formats including QR Code, PDF-417, EAN, UPC, Aztec, Data Matrix, and Codabar.

The library solves the problem of working with barcodes in .NET applications by providing a hand-ported implementation of the original Java ZXing library, with optimizations and improvements made during the porting process. It supports decoding of formats including UPC-A, UPC-E, EAN-8, EAN-13, Code 39, Code 93, Code 128, ITF, Codabar, MSI, RSS-14 variants, QR Code, Data Matrix, Aztec, and PDF-417. Encoding is supported for UPC-A, EAN-8, EAN-13, Code 39, Code 128, ITF, Codabar, Plessey, MSI, QR Code, PDF-417, Aztec, and Data Matrix.

Developers should choose this tool if they need barcode functionality across a wide range of .NET platforms and frameworks. The library offers extensive platform coverage including .NET 2.0 through 7.0, .NET Standard, .NET Core, UWP, Xamarin.Android, Unity3D, and Windows RT, with additional bindings available for imaging libraries such as ImageSharp, SkiaSharp, OpenCVSharp, and EmguCV. It also supports COM interop for use with VBA. The project includes multiple demo clients demonstrating both static image processing and camera-based decoding across Windows Forms, WPF, Windows RT, Unity3D, and various computer vision frameworks.

The project maintains active support across its broad platform matrix with bindings and assemblies regularly updated for current .NET versions. Demo applications span multiple UI frameworks and integration scenarios, indicating ongoing effort to support diverse use cases. The library is distributed through both direct releases and NuGet, providing accessible installation paths for adopters.
