Breakpoint not hooked up when debugging in VS.Net 2005

Question

Been running into this problem lately... When debugging an app in VS.Net 2005, breakpoints are not connected. Error indicates that the compiled code is not the same as the running version and therefore there's a mismatch that causes the breakpoint to be disconnected.

Cleaned solution of all bin file and re-compile doesn't help. Not just happening on a single box or person either.

Added Note: This solution is in TFS for Source Control. If I delete my local TFS repository and get it from source control from scratch, SOMETIMES the problem goes away. I've also tried un-installing and re-installed Visual Studio. That also SOMETIMES helps. That fact that both of those work some of the time indicates that the problem isn't caused by either directly.

Answer 1

Maybe this suggestion might help:

1. While debugging in Visual Studio, click on Debug > Windows > Modules. The IDE will dock a Modules window, showing all the modules that have been loaded for your project.
2. Look for your project's DLL, and check the Symbol Status for it.
3. If it says Symbols Loaded, then you're golden. If it says something like Cannot find or open the PDB file, right-click on your module, select Load Symbols, and browse to the path of your PDB.

I've found that it's sometimes necessary to:

1. stop the debugger
2. close the IDE
3. close the hosting application
4. nuke the obj and bin folders
5. restart the IDE
6. rebuild the project
7. go through the Modules window again
8. Once you browse to the location of your PDB file, the Symbol Status should change to Symbols Loaded, and you should now be able to set and catch a breakpoint at your line in code.

Source: The breakpoint will not currently be hit. No symbols have been loaded for this document.
