I found a simple tool on the web today: Linecounter: http://dotnetjunkies.com/WebLog/johnwood/archive/2005/01/08/42690.aspx
So I ran a silly test
LLBLGen Pro designer: Totals: lines=79294 files=187 projects=5
Code generator (taskperformers etc.): Totals: lines=11352 files=27 projects=4
Runtime libs: Totals: lines=42494 files=76 projects=7
Drivers: Totals: lines=22183 files=46 projects=8
In total, that's 155323 lines of C# ! . (started jan 3, 2003).
THAT's why my fingertips hurt so much!
