symbols are created but debugging never stops at break point

Question

How do I get my breakpoints working?

I am getting this message when running a C# console app in debug mode:

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

Other references not covered by nuget:

1. The solution is made up of 2 projects: consoleProject, classLibraryProject.
2. consoleProject references classLibraryProject.
3. When going to debug->windows->Modules for classLibraryProject I am getting the message "Could not find or open the PDB file.
4. When manually building the PDB for classLibraryProject and moving it into the bin\Debug for consoleProject, then I get a symbol status of "Symbols Loaded." **However, the breakpoints are not honored. **
5. Yes, I am certain that the code is triggered because the side effects of the code are visible.

How do I get my breakpoints working?

Answer 1

I just created new console app + class library. Please be sure that console app has reference on class library (like on image)

I wrote that because I don't see that on your screens.

Than plz right click on solution and select "properties..." You will see smth like that: Check that configuration + platform are equal for your projects and that checkboxes 'Build' are both selected. If that checkboxes are selected then after 'clean build' of you solution you will see smth like that in the bin\Debug folder of colsole app:

Please notice that class library has 2 files (highlighted on screen): dll + pdb. In that case dll+pdb are in synchro state and your breakepoints will work in class library code.

If you have no pdb file for class library project after build than may be your reference on class library is NOT a reference on a VS project. Please check that you added reference correctly (like on image):

DO NOT reference on dll file of class library directly via 'Browse' dialog.

You can check that your console app refenced correctly on class library project - please open console app csproj file on edit and look on reference:

If you have BAD refence (on a .dll file):

than delete that reference via context menu in VS and add a correct one.

I hope that will help you.

Answer 2

You have my sympathy for trying to fix this. When I compare settings with mine I find 2 differences in Debugging|General:

1. check: Suppress JIT optimization on module load
2. uncheck: Load dll exports

The first one may fix your problem.
