I was going to debug my asp.net app, while running the website, i placed a breakpoint, but it was not hitting that breakpoint during the execution cycle. I tried to do it through “Attach to Process” method, and attaching my Visual studio debugger to w3wp.exe.

Still no clue, i searched a bit of options in the Tools -> Options -> Debugging -> General and un-check the option that says “Require source files to exactly match the original version”

This will make life easier, and enable us to debug the solution. Phew!!
