How to find corresponding .pdb inside .NET assembly?

Apparently, when a .NET assembly is created the location of the corresponding .pdb file path is included inside. Link for reference:

How do I access this? I have tried using ILSpy to look inside my assembly but could not find.

Answer

You can use the dumpbin tool from a Developer Command Prompt, e.g. a cmd line like this

dumpbin /HEADERS YourAssembly.exe   

would show the path to the PDB file in the Debug Directories section similar to this

Microsoft (R) COFF/PE Dumper Version 14.00.24213.1
