[IDE-Visual Studio]The breakpoint will not currently be hit. No symbols have been loaded for this document.[Reshipment]

When debugging my application I encounter a problem with error message "The breakpoint will not currently be hit. No symbols have been loaded for this document.", which I fould in the end is due to the assembly loaded from GAC not the bin folder. The passage blow helped me a lot during the problem solving. I post this blog is to remind myself...

 

[Reshipped from Doug] ==================

In the Visual Studio IDE, when I set a breakpoint at a line of code, and start debugging, the breakpoint becomes that hollow maroon circle with a warning that says The breakpoint will not currently be hit. No symbols have been loaded for this document.

 

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.

Look for your project's DLL, and check the Symbol Status for it.

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

stop the debugger

close the IDE

close the hosting application

nuke the obj and bin folders

restart the IDE [Nick - This step is necessary]

rebuild the project

go through the Modules window again

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.

I'm not really an expert on this, but I welcome any questions anyone may have, and I'll try to help out if you still can't get it to work.
