Possible Duplicates:
Is there a site that emails out daily C# tips and tricks?
What are your C# Commandments?
A little background: I have skimmed through Effective C# by Bill Wagner. I know that my opinion on a book like that is too insignificant. But, still just for record I plan to read and re-read the books for years to come. It is just too good.
Now the question: Can SO C# gurus tell me their favorite C# tip(s) to make their code effective.
EDIT: I looking for something that C# gurus use in their day-to-day coding to make it effective. I am not looking for hidden features of C#. If this has already been answered let me know. Thanks.
