Summary0003032: Natvis not working / PDBs missing
Description

As per thread https://www.noesisengine.com/forums/viewtopic.php?t=3193, the Natvis file/functionality is not working in a C++ build and may require the PDBs.

Steps To Reproduce
  1. Set up some project using the publicly-available, non-PDB build
  2. Attempt to debug the project
  3. Observe the complete lack of symbols for Noesis types
PlatformAny

Even with the PDB, it seems we are not linking the Natvis file (/NATVIS must be used as explained here https://learn.microsoft.com/en-us/cpp/build/reference/natvis-add-natvis-to-pdb?view=msvc-140).

I need to figure this out. Meanwhile I am attaching our latest natvis file here.

https://developercommunity.visualstudio.com/t/c-library-natvis-not-loaded/136621

Additionally if you load a natvis embedded into a dll's pdb, the natvis only applies
when stepping through code in the dll (as opposed to when it's part of the project,
it will load for all stack frames).

So it seems, embedding the NatVis in the PDB is not going to work as we want and we are going to need to distribute the NatVis in the SDK.
