Generate PDB from .NET DLL file?

Question

I need something that can generate a PDB from a DLL file (C# .NET code), is there any free program to do that?

If you need to debug a thirdparty assembly without sources, then dotPeek and ReSharper will be extremely helpful having an option to generate PDB from DLL. In ReSharper, this can be done through ReSharper > Windows > Assembly Explorer by opening necessary assembly and clicking "Generate Pdb...":
