I've added it to my forms project, have the suggested code:
MobileBarcodeScanner scanner = new MobileBarcodeScanner();
Result result = await scanner.Scan();
if (result != null)
{
ContentPage.ScanResult scanResult = ContentPage.ProcessScanResult(result.Text);
await iScanParent.ProcessScan(scanResult);
}
I can step through it in debug mode, but the call to Scan() just does nothing. App keeps working, but no scanner appears. Is there something obvious I have missed?
