Installing Boost v1.70 in Visual Studio 2019 using Nuget

I'm learning C++, some of the Boost libraries and VS2019 Community Edition. I'm currently reading through the Boost website's online material and the book Learning Boost C++ Libraries, trying to follow along. I would like to update to 1.70.0 and figure out exactly why my code is building correctly. I know, I know...if it's working why question it? Well, the truth is I just don't understand why!

I wasn't aware of Nuget and vcpkg prior to downloading and installing Boost 1.68.0 manually (BTW, there seems to be way too many ways of installing the libraries and it's quite confusing). I have since deleted the original Boost installation directory and tried to install the Boost libraries through Nuget in VS2019. This didn't appear to be successful (although I suspect vcpkg (see below) has something to do with it). I was getting a single linker error (can't find the .lib file) which I eventually resolved (don't ask me how...it's a confusing story involving creating a new project and cutting/pasting my code. Now it works; go figure).

Currently, when I begin an #include directive () in my code I can see the path to the files which is buried under D:\...\vcpkg\installed\x86-windows\include\boost. I've never used vcpkg directly so I have no idea why it's there. The Property Pages for the project don't list the paths under C/C++ > Additional Include Directories or under Linker > Additional Library Directories so I haven't a clue from where the compiler and linker are getting the references. There appear to be no packages installed under the Nuget UI.

Ideally, I would like to start over with the Boost installation and use VS internal tools to do so. I will probably have several different VS solutions as I explore Boost and would prefer Boost to be available to all future projects. Is that possible?

Any advice?

One thing to keep in mind is that the "boost" package only installs the header only libraries, it doesn't install all the libraries that require a binary library.

To install the binary libraries, you need to install individual packages, for instance "boost_log-vc141" is the boost logging library.

First, install the boost package into your project using NuGet. You should see a packages.config added to your project that looks like this:

<?xml version="1.0" encoding="utf-8"?>
<packages>
  <package id="boost" version="1.70.0.0" targetFramework="native" />
</packages>

Next, include the desired boost header file:

#include <boost\array.hpp>

You can confirm that the header is being loaded from the correct path by placing the caret after the hpp, pressing CTRL+SPACE, then hovering hovering over the item in the context list:
