We have just released Aspose.BarCode for .NET hotfix v3.6.1. It supports reading Aztec barcodes. Sample code:

// read or decode Aztec barcode
BarCodeReader reader = new BarCodeReader(“aztec.png”, BarCodeReadType.Aztec);
while (reader.Read() == true)
// display the detected codetext
Console.WriteLine(“Codetext: " + reader.GetCodeText());
// close the reader

Some bugs were also fixed in this hotfix. For release notes and download, please visit http://www.aspose.com/community/files/51/.net-components/aspose.barcode-for-.net/default.aspx.
