The dmd backend should generate .pdb files for visual studio.

I think it time for dmd to do so, as the backend is currently 
opensource. The fine folks at llvm created documentation for the 
PDB file.
https://llvm.org/docs/PDB/index.html
By doing so, the visual studio debugging experience would be much 
smoother as the debugging information is now generated for types 
correctly, without having to rely on converting the dwarf 
information into a .pdb file.

Anyone else interested in generating .pdb files?
