Visual Studio: Debugging a referenced DLL, I have source in another SLN

I am trying to debug a project that has a reference to a DLL that I added, the DLL is stored in an external directory and I just added a reference. Now of course I can debug my project but the line that calls a method on my other dll I can't step into it, i.e. F12.

One way I was able to do this was to add my project (dll) as an existing project to my solution and replace the referenced dll to use the attached project rather than a file on disk.

But what a mess, I am sure there is a cleaner way?

I seem to remember if I copy some PDB files or something but i can't remember. And Do i need to open 2 copies of visual studio, 1 for my main project and 1 for my referenced DLL??

Rebuild the second solution in Debug mode on your own machine (so that file paths in that PDB are specific to your machine).

Copy both the .DLL and .PDB files to your references folder. Visual Studio will pick up the .PDB file automatically and use the file paths to show source.

You can also use Symbol Server and Source Server to achieve this when the referenced assembly is built elsewhere:
