I've just rejoined a C# project and my breakpoints stopped working in Visual Studio 2005. Needless to say, this was hugely annoying.
It seems this is quite common though, Googling provided the following solutions :
- Disable "Just my code" setting in debugging options.
- Manually select "Managed code" when trying to attach to the IIS process at the start of debugging.
- Change project properties to "debug" instead of "release"
None of these helped me, and I was about to attempt some more arduous solutions such as:
- rebuilding the GAC
- deleting all temp files associated with my project.
...however, my helpful colleague Miklos worked out a fix. I had to :
- Rebuild All from my top level solution
- Then navigate to any page on the site, so that all DLLs are loaded
- Then (and only then) attach to process and debug as normal.
This works well for me on this particular project, thanks Mik!
