How to load symbols in Visual Studio 2012

Question

When I am debugging my app I see messages:

cannot find or open the PDB file

I seem to remember being able to specify the location of the PDB file while debugging the app. How can I do this? I'm using Visual Studio 2012.

Marbut

OK , I figure out how : Debug - Windows - Modules and then right click on the dll to load the pdb . Problem now is that it tells me "A matching symbol was not found in this folder." Even though the pdb and dll names match . – Marbut

I added the pdb files to the same directory as the dlls and then they were loaded successfully . – Marbut

You should answer your question instead of commenting on it. Thanks alot. – Deciare

Answer 1

Adding Symbols Location

Open Settings: Tools -> Options -> Debugging -> Symbols and add directory, where your .PDB files are located.

You can add custom path, like for each project, and also you can edit common path, where Visual Studio will save all .pdb cache.

Making post-build script

I made in each project post-compile event, which copy all .pdb to one folder, by this i have all in one place. But you can store it separately, which i found not so convenient, as it require each time edit list of locations.

Example of post-debug script to copy .pdb and .dll to Symbols cache location:

xcopy /Y /R "$(TargetDir)$(ProjectName).pdb" "D:\VS_CACHE\"
xcopy /Y /R "$(TargetDir)$(ProjectName).dll" "D:\VS_CACHE\"

Solving problem if symbols not found

When you in debug mode, and for some reason symbols not found, it can be because of multiple reasons:

1. You have .pdb in Symbols cache, but it's outdated (you can get if this a case, if you put breakpoint in code and hover it)
2. You have multiple .dll which use this part of code (you can get if this a case, if you put breakpoint in code and hover it)
3. Symbols not loaded, in this case you can check it by going to: Debug-> Windows -> Modules and trying to load needed module.

Making Debugging more easy:

To re-attach VS Debugger to running application, i recommend to use this free Visual Studio add-on (support VS 2015):

ReAttach: visualstudiogallery.msdn.microsoft.com/8cccc206-b9de-42ef-8f5a-160ad0f017ae

It will save you a lot of time! :)
