A package manager, based on a central installation database, is a tool that automatically installs, updates and removes distributions of software. With a package manager, users do not need to manually download an application installer. There are many package managers working for different programming languages and platforms, such as Maven, npm, pip, apt-get, Yum, Homebrew and so on. In this post, let’s take a glimpse of how to publish and install packages with NuGet.

What is NuGet

NuGet is the package manager for the Microsoft development platform. Users could use NuGet via command line tool, Visual Studio or NuGet Package Explorer.


You can also install NuGet Package Manager in Visual Studio. Select the Tools > Extensions and Updates menu option, and then search for NuGet:

Once the extension is installed, you can find it from the Tools > NuGet Package Manager menu option:

How to Publish a Package

Before creating a package, we need to know how to layout the directory structure :

  • tools  – the folder is for PowerShell scripts and programs that accessible from the Package Manager Console.
  • lib  – the folder is for .dll  files which are added as assembly references when the package is installed.
  • content  – files in the folder are copied to the root of your application when the package is installed.
  • build  – the folder is for MSBuild targets files that are automatically inserted into the  .csproj  file of the application.
