If by "WF" you mean WinForms: It's not related. You could also implement it in a console application.

I assume you don't want to use a QR/Barcode-Scanner for that, otherwise it would be trivial.

So first you have to get the image somehow into your application. How exactly will depend on the device you'll be using for this: webcam / mobile phone / XY. This still isn't related to QR code recognition - so decide on some device and look for a solution on how to get the image into your application.

Then you'll need to process the image and recognize the QR code. There are several open source solutions available, take a look:
Open Source QRCode Library[^]
Capture QR code in Windows 8.1 using CaptureElement sample in C#, XAML for Visual Studio 2013[^]
ZXing.Net - Home[^]
Barcode Scanner - Home[^]
