I have some source code that has successfully build a project complete with EXE and PDB files from a command line build. I wonder how I can debug this using Microsoft Visual Studio 2005 without an SLN file or any project file at all. The PDB file is supposed to be a database file of debug symbols. The program has lots of DLL’s with their matching PDB files. I wonder if there is a way to “attach” a dll to a debug process.
