How do you scan QR codes and barcodes in Windows 10 Mobile?

[Windows Central]

One question we see a lot of around these parts is how do you scan QR codes in Windows 10 Mobile?
Back in the days of Windows Phone 8.1 you could just launch the camera and dive into Lenses for Bing Vision. That app from Microsoft included a nice QR and barcode scanner, but it has since been deprecated and is not even in Windows 10 Mobile.

Unfortunately, for now, the short answer to the QR question is you need a third-party app in Windows 10 Mobile. Seeing as Windows 10 Mobile is not yet complete Microsoft could still cram one in somewhere. However, we don't see this feature exactly being a priority for them either.
