在Visual Studio中调试引用的DLL

Question

I have multiple projects (lets call one MyLibrary ) in Visual Studio that contains a lot of nifty functions and classes I use in my other projects. I add a reference to MyLibrary.dll directly and not the project itself.

However, I now need to breakpoint my way through something in MyLibrary while I run one of my other projects. How can I debug my dll the way I've set up my projects? I know for a fact I've done it earlier with these projects, but since I didn't do anything special, I don't know what's missing.

I've turned off Just-my-code and followed some tips like that, but I haven't gotten into .pdb's yet. If I need one to debug another DLL, I would appreciate some information on how to export that from MyLibrary .

Answer 1

You might need to go to the properties of a DLL, and ensure that Copy Local is set to True. Otherwise, Modules won't be able to find the .pdb for your reference

If that doesn't help you can try to rebuild your external library using debug mode, then copy manually both .dll and the .pdb file to the bin of your app.

Answer 2

While debugging, check in Debug/Modules, if your dll symbols are loaded. If not, let them load. You may be asked to set the folder with pdb files. Pdb contains the symbol used for debugging. It has to be the same version as dll file you are using in your projects. After that you will be able to debug the library.
