In VS, you can have your strings colorized. This feature has been around for a long time. However, the default string color is the same as the default text color, so you may not notice at first.
In C#, there are two string colors: “String” and “Verbatim String”. In Whidbey, I'm pushing to have both string colors be the same as each other, but different than other colors. I also like to set the colors for “Number“ and “Operator“. In the past, I've found this colorization very helpful in reading my code.
As I work at my OO skills, the significance of literal strings in my code has decreased, and all my code has become simpler, so maybe this is changing for me.
