Samidip Basu presented on the "7 Deadly Sins for Windows Phone Developers". The 7 sins discussed were: Pride (overconfidence), Envy (jealousy), Sloth (failure to utilize resources), Wrath (uncontrolled rage), Greed (desire for quick riches), Gluttony (over-indulgence), and Lust (excessive desires). For each sin, Basu provided examples of how developers could manifest that sin and recommendations for avoiding those pitfalls when developing for Windows Phone. The overall message was how to develop apps responsibly by leveraging the platform's capabilities and existing resources rather than reinventing the wheel or being overly ambitious.
