NuGet (pronounced "New Get")[2] is a package manager designed to enable developers to share reusable code. It is a software-plus-service solution whose client app is free and open-source. The Outercurve Foundation initially created it under the name NuPack.[3][4] Since its introduction in 2010, NuGet has evolved into a larger ecosystem of tools and services.[5]


NuGet is a package manager for developers. It enables developers to share and consume useful code. A NuGet package is a single ZIP file that bears a .nupack or .nupkg filename extension and contains .NET assemblies and their needed files.[6]

NuGet was initially distributed as a Visual Studio extension. Starting with Visual Studio 2012, both Visual Studio and Visual Studio for Mac can natively consume NuGet packages. NuGet's client, nuget.exe is a free and open-source, command-line app that can both create and consume packages. MSBuild and .NET Core SDK (dotnet.exe) can use it when it is present.[6] NuGet is also integrated with SharpDevelop.

It supports multiple programming languages, including:

Chocolatey[10] is a machine-level, command-line package manager and installer for Windows software. It uses the NuGet packaging infrastructure and Windows PowerShell to simplify the process of downloading and installing software.[11]

In April 2014, Microsoft debuted OneGet (later renamed PackageManagement) alongside PowerShell 5. It is a free and open-source package-provider manager, which provides a way to integrate other package managers into PowerShell. OneGet was pre-configured to browse the Chocolatey repository.[12][13]

The name is an extension on a pun of NuGet (from "nougat") "because everyone loves Chocolatey nougat".[14]
