For some reason, vs.net just will not hit any breakpoints that I have set. The project is set to debug as opposed to release, and debug is set to true in the compilation tag of the web.config file. I added smartnavigation to a page, but it was causing strange behavior, so I removed it. Now now breakpoints will be hit. Has anyone experienced anything like this before. As link9 suggests, I repented and rebooted, but vs.net still will not hit a breakpoint??? Any suggestions?
