I'm writing a custom page provider, I've got it all set up and working but I'm not seeing my pages under the entry point. So I'm trying to debug it but I'm hitting problems. I've managed to get it to hit a breakpoint once but it "forgot" what line it was on when I hit F10. I'm definitely attaching to the correct process (only one w3wp on the box).
I've tried attaching before I load EpiServer, after, on the admin screen. Nothing. Reset IIS. Clear ASP.NET cache... Any other pointers?
Seems your symbols are a bit out of synch.
Try doing a full clean and re-build of your solution before attaching the debugger.
