ZXing.Net is a .Net port of the original java-based barcode reader and generator library zxing written by Michael Jahn.
ZXing.Net.Mobile uses ZXing.Net to detect and generate barcodes by providing UI related API's to load camara previews in realtime to detect barcodes from the camera preview feed.
While ZXing.Net does ship as a nuget package, it unfortunately has an issue with bait and switch. Until this is resolved it is easiest to just consume the netstandard2.0 implementation binary directly in this repo.
