debugging information cannot be found or does not match visual studio's

Question

I copied an existing project and renamed the folder. Now I get this error when I try to compile the application

debugging information cannot be found

Answer 1

The main reason is that you don't have a matching pdb and exe.

Some possible solutions:

• You are compiling in release instead of debug
• You need to clean/build or rebuild
• You don't have your pdb files being generated in the same directory as the exe
• You have a mismatching pdb, maybe the copied source is newer than today's date and something isn't building properly.
• Try cleaning out all debug object files
• You are attaching to a process that you started from a different location from where your build exe and pdb exist
• Restart Visual Studio
