You can use this library: http://qrcodenet.codeplex.com/

It basically generates an image or a stream with your QR Code.

Newly released Acronis True Image 2019

In announcing the release of the 15th Anniversary Edition of Acronis True Image 2019, the company revealed that its artificial intelligence-based anti-ransomware technology – stopped more than 200,000 ransomware attacks on 150,000 customers last year.

Alexandre SimõesManager / Technology SpecialistCommented:
You don't need to store it, but you can and probably should cache it.

Anyway, as this library also returns a stream, you can return an image directly from memory.

The best way is to do this logic in an http handler that receives whatever makes sense, like an item ID, and returns an image.

How about using the google chart API?

Your ,net will have to url encode the text, and pass it a parameter to the google API.
For example, the following QR code is a link back to this question

http://chart.apis.google.com/chart?cht=qr&chs=300x300&chl=http%3A//www.experts-exchange.com/Software/Server_Software/Application_Servers/.Net/Q_28551019.html%3Fcid%3D1752&chld=H|0

You can embed it directly into your html

@shalomc idea works and is much faster to implement.
I guess I just wouldn't rely on an external service for this.

I just went to check if the Google API still has the request limits but apparently not, so you're safe :)
