I keep looking for simple books for programming C# but even the learn in 21 days books are trying to teach too much. I’d hazard to say 99% of any code needed to be written by testers is simple file manipulation. You need to know about int, string, building console apps, finding files, opening and saving files, loops, and simple string replacement and verification. That’s about it. I’m working on a paper to teach that basic things right now. I think it might be useful. Guess I’ll find out.
