Scott Mitchell is a well-known author of ASP. NET technology. I have several Mitchell books on my bookshelves, which he published on msdn. ArticleIs ASP. NET 2.0 is a step-by-step tutorial developed in 3-tier development. If you think that petshop 4.0 is too abstract to understand the true meaning of 3-tier development, we suggest following the guidance of Mitchell step by step, go to the 3-tier development Temple. This series of articles have not been written yet. If there are any updates at any time, I will also update the link immediately.
