A new feature has been introduced in SharePoint 2016 IT Preview that allows users to share documents using QR codes. By default, each documents library has this feature enabled. Simply upload a document to a document library, and using the document properties overlay, you can generate a QR code for the document.
Clicking this icon will automatically bring the user over to a new application page (/_layouts/15/qr.aspx) which will generate a QR code.
hmm. I just tried this and received a “An error occurred during the compilation of the requested file, or one of its dependencies. ” I have the RC Refresh patch installed.
I just tried reproducing your issue by rebuilding a fresh environment, but I am able to get the QR code just fine. Do you get the error upon clicking the QR code button from the hover panel? Do you have a correlation ID alons with more info from the logs?
