When i'm working in visual studio and need to check something stupidly simple, like testing a string format, I think twice before opening linqpad just because it somehow seems like a cop-out, i.e. seems like I'm being unproductive so has a bad "feel" to it. If however Linqpad was always running when I open visual studio then there would not be any "stigma" attached to quickly checking something in linqpad, because it would be right there.

Ideallly linqpad should replace the immediate window... THAT would be justice! he he...
