One friend of mine is beginner programmer and he is trying to learn classic ASP.NET. I want to recommend him some small open source application to study. I don't want to confuse him with advanced topics or mislead him with wild approaches. What application should I recommend to him?
Edit: I clearly failed to ask this question. I am not looking for beginner tutorial or set of examples. I am looking for real life application which helps him make better pictures how all samples he already look at works together.
