Does signing a DLL invalidate a PDB file?

Question

Hi,
I have signed my dll using SignTool.exe with timestamp. No the timestamp of dll and pdb file are different.
Does signing the dll invalidate the pdb file?
How exactly pdb works?

Answer 1

No, signing a dll or an exe does not invalidate the related pdb (symbol file).
