.NET

I do agree that per dev is such a weird way to do licensing.

Related - I was teaching at a school where I wanted them to get some plagiarism tool. The charge was per student. It was a newish school with a lot of growth, and another new school was still being built nearby (not being put into service for another year or two), so the school had A LOT of students (nearly 2 school's worth), so, they couldn't afford it. I ended up having to manually copy some of my student's code and then Google it to see if they had copied it from anywhere (and yes, some of them had. BTW the most hilarious poor effort at trying to cheat was one who's code not only didn't even compile, but they hadn't even bothered changing the Imperial measurements to Metric! Didn't even need to Google that one - here's your letter to parents 😂).
