I have an ASP.NET web aplication using vs2008. It used to let me hit my break points but for some unknown reason in this site it won't let me hit them any more. I have set everything to debug and re built about a million times and everything else but can't seem to hit that damn break point!!! Break points work for the site but not the class libraries I add in, but they used to!!

I can't see anything in the web config or the configurations to change anything. I've added the class library to a test solution, works fine.

Does anyone have any ideas?

  • How are adding the class libraries? By Project Reference? – Mike Miller Jan 09 '12 at 16:57
  • Is the class library set to release mode? That will cause it not to hit break points while debugging. – Justin Jan 09 '12 at 16:58
  • @Funky- This is the worst! For me, the symbol cache would not rebuild. The only cure I found was completely shutting down VS and restarting. Make sure all related process are killed--devenv, your app process, etc. – Matt Cashatt Jan 09 '12 at 17:02

Just to confirm, breakpoints work for the site but not for the class library. That means VS is attaching to the right instance. Put a break point right before the class library is invoked and see if it will drill in. If visual studio can't generate the metadata for debugging, it does a jump over. Confirm you also have the PDB file from the class library present. Also, if you've recently updated the class library, be sure to stop Cassini and restart.
