I launched the library in October 2013, not primarily because I lacked other tools at the time, but as a personal programming challenge: My goal was to implement the official DIN/ISO standard for QR codes natively in C# from scratch myself. To understand the algorithms, to learn something new.
Over the years, this experiment has grown into a very successful open-source project that has now been downloaded millions of times via NuGet and is used in numerous commercial and private projects worldwide.
After 12 years, I decided in September 2025 to hand over the active maintenance and administrative management of the project. In this brief post, I would like to explain the background behind this decision and introduce the new maintainer.
The Reasons for the Transition

And what way seems to be more suitable than implementing a QR code generator by yourself?
