I got the above error in VS 2008 with a web project in localhost while I put a breakpoint. It used to work fine and suddenly happened yesterday. I deleted BIN folder and added all references from scratch. I also deleted solution file and recreated project. I rebooted the machine also. I checked the build is debug mode and used rebuild all several times. Googled around but still can not figure it out. I searched disk, can not find any PDB files. Strange enough, some files can be debugged (in same folder with same extension). If I put System.Diagnostics.Debugger.Break() at the line, VS does break into debug mode, so the line of code is reachable.

what else could I try?

One thing is to check the Dropdown list in visual studio for the build configuration (Usually Debug or Release). If you change the configurations, it could prevent a project from being built, which can cause that error.

yes, it is DEBUG. some files in the project can add breakpoint without error.

Just for giggles and grins, go into that dropdown list and choose Configuration Manager, and make sure the projects in question are in fact checked to build.

Only other thing i can think of is to delete the obj folder and rebuild it. I ran into that quite a bit when i had several projects in one solution, and only chose to build certain ones in the Configuration Manager.

Check this out:

One of the common answers was to close VS, delete the .suo (solution user options) file, then reopen the project. See if that works.

Thanks, I delete the contents of the following folder, although the error is still display but VS does break at that line. cheers
