I thought I would experiment a little with reading QR codes, so started a new .NET project and installed, via NuGet, FreeSpire.Barcode version 6.6.0. When I attempt to decode a barcode (be it a QR code, or an 1D barcode), I get the error message "Not supported in Spire.Barcode Evaluation version".
Did I download or otherwise get the wrong library? I was attempting to install the "Free Spire.PDF for .NET" edition.
