How C# Save My Marriage, Enhanced My Career, and Made Me an Inch Taller, Scott Hanselman
- 1. Giant Disclaimer I’m here as me, doing my thing. These opinions are mine, Scott Hanselman. If I say something stupid and you’re a journalist, make sure to quote me as “Scott Hanselman, Stupid Guy.” I’m not the manager of anything important at Microsoft. I am a member of the .NET Community. I care.
