Just right-click on a project (any C++ project would do) in “Solution Explorer” and select “Manage NuGet Packages…”</p> <p><img alt src=../nuget/nuget-search-package.png></p> <p>Now you can click on “Browse” tab and find the package you like to install.</p> <p><img alt src=../nuget/nuget-select-package.png></p> <p>Most of the packages in NuGet gallery are .NET packages and would not be useful in a C++ project. Microsoft recommends adding “native” and “nativepackage” tags to C++ NuGet packages to distinguish them, but even adding “native” to search query would still show many .NET-only packages in the list.</p> <p>Nevertheless, after finding the package you want, just click on “Install” button and accept confirmation dialogs. After the package is successfully added to the projects, you should be able to just build and execute the project without the need for making any more changes to build settings.</p> <div class="admonition note"> <p class=admonition-title>Note</p> <p>A few notes:</p> <ul> <li>NuGet packages are installed per project and not system-wide. The header and binaries for the package are only available to the project it is added to, and not other projects (obviously unless we add the package to those projects as well)</li> <li>One of the many great things about your elegant work is that it is a header-only library, which makes deployment very straightforward. In case of libraries which need binary deployment (<code>.lib</code>, <code>.dll</code> and <code>.pdb</code> for debug info) the different binaries for each supported compiler version must be added to the NuGet package. Some library creators cram binary versions for all supported Visual C++ compiler versions in the same package, so a single package will support all compilers. Some others create a different package for each compiler version (and you usually see things like “v140” or “vc141” in package name to clarify which VC++ compiler this package supports).</li> <li>Packages can have dependency to other packages, and in this case, NuGet will install all dependencies as well as the requested package recursively.</li> </ul> </div> <p><strong>What happens behind the scenes</strong></p> <p>After you add a NuGet package, three changes occur in the project source directory. Of course, we could make these changes manually instead of using GUI:</p> <p><img alt src=../nuget/nuget-project-changes.png></p> <ol> <li> <p>A <code>packages.config</code> file will be created (or updated to include the package name if one such file already exists). This file contains a list of the packages required by this project (name and minimum version) and must be added to the project source code repository, so if you move the source code to a new machine, MSBuild/NuGet knows which packages it has to restore (which it does automatically before each build).</p> <div class=highlight><pre><span></span><code><span class=cp><?xml version="1.0" encoding="utf-8"?></span> |

In case of this library for example, it contains <code>json.hpp</code>:</p> <p><img alt src=../nuget/nuget-package-content.png></p> <div class="admonition note"> <p class=admonition-title>Note</p> <p>This directory should not be added to the project source code repository, as it will be restored before each build by MSBuild/NuGet. If you go ahead and delete this folder, then build the project again, it will magically re-appear!</p> </div> </li> <li> <p>Project MSBuild makefile (which for Visual C++ projects has a .vcxproj extension) will be updated to include settings from the package.</p> <p><img alt src=../nuget/nuget-project-makefile.png></p> <p>The important bit for us here is line 170, which tells MSBuild to import settings from <code>packages\nlohmann.json.3.5.0\build\native\nlohmann.json.targets</code> file. This is a file the package creator created and added to the package (you can see it is one of the two files I created in this repository, the other just contains package attributes like name and version number). What does it contain?</p> <p>For our header-only repository, the only setting we need is to add our include directory to the list of <code>AdditionalIncludeDirectories</code>:</p> <div class=highlight><pre><span></span><code><span class=cp><?xml version="1.0" encoding="utf-8"?></span> |

It is added as None (no build action) and removing it wouldn’t affect build.</p> </li> <li> <p>Lines 172-177 check to ensure the required packages are present. This will display a build error if package directory is empty (for example when NuGet cannot restore packages because Internet connection is down).
