PackageManagement (aka OneGet)

What's New

PackageManagement is supported in Windows, Linux and MacOS now. We periodically make binary drop to PowerShellCore, meaning PackageManagement is a part of PowerShell Core releases. Also PackageManagement and PowershellGet Modules are regularly getting updated in

Thus checkout the latest version from

Get Started!

OneGet is shipped in Win10 and Windows Server 2016! For downlevel OS, you can install the WMF 5.0 RTM or WMF5.1 Preview and then start using the OneGet.

You can follow @PSOneGet on Twitter to be notified of every new build.

What is PackageManagement (OneGet)?

OneGet is a Windows package manager, renamed as PackageManagement. It is a unified interface to package management systems and aims to make Software Discovery, Installation and Inventory (SDII) work via a common set of cmdlets (and eventually a set of APIs). Regardless of the installation technology underneath, users can use these common cmdlets to install/uninstall packages, add/remove/query package repositories, and query a system for the software installed.

With OneGet, you can

  • Manage a list of software repositories in which packages can be searched, acquired, and installed
  • Search and filter your repositories to find the packages you need
  • Seamlessly install and uninstall packages from one or more repositories with a single PowerShell command

PackageManagement Architecture


Let's Try it


  • Windows 10, Windows Server 2016, or down-level Windows OS + WMF5
  • Linux or Mac with the PowerShellCore

NuGet provider is required to continue
PowerShellGet requires NuGet provider version '' or newer to interact with NuGet-based repositories. The NuGet provider must be available in 'C:\Program
Files\PackageManagement\ProviderAssemblies' or 'C:\Users\jianyunt\AppData\Local\PackageManagement\ProviderAssemblies'. You can also install the NuGet provider by
running 'Install-PackageProvider -Name NuGet -MinimumVersion -Force'. Do you want PowerShellGet to install and import the NuGet provider now?

Try the latest PackageManagement (OneGet)

You can run install-module PowerShellGet to install the latest PackageManagment and PowerShellGet from PowerShellGallery.

Downloading the Source Code

OneGet repo has a number of other repositories embeded as submodules. To make things easy, you can just clone recursively:

git clone --recursive

If you already cloned but forgot to use --recursive, you can update submodules manually:

git submodule update --init

Building the code

# After cloning this repository, go to the project folder:
> cd oneget
> cd src

# download the dotnet cli tool
> .\bootstrap.ps1

# building OneGet for fullclr
> .\build.ps1 net451

#building OneGet for coreclr
> .\build.ps1 netstandard1.6
> .\build.ps1 netcoreapp2.0

If successfully built above, you should be able to see a folder: oneget\src\out\PackageManagement\ whose layout looks like below:

  • coreclr
  • fullclr
  • PackageManagement.format.ps1xml
  • PackageManagement.psd1
  • PackageManagement.psm1
  • PackageProviderFunctions.psm1

Deploying it

Generate PackageManagement.nupkg

We can use publish-module to create a .nupkg. Assuming you want to put the generated .nupkg in c:\test folder. You can do something like below. Note I cloned to E:\OneGet folder.

cd E:\OneGet\oneget\src\out\PackageManagement
Register-PSRepository -name local -SourceLocation c:\test
Publish-Module -path .\ -Repository local
PS E:\OneGet\oneget\src\out\PackageManagement> dir c:\test\PackageManagement*.nupkg

   Directory: C:\test

Mode                LastWriteTime         Length Name
----                -------------         ------ ----
-a----        11/4/2016   4:15 PM        1626335 PackageManagement.

Then you can do

find-module -Repository local
install-module -Repository local -Name PackageManagement

to get the newly built PackageManagement on your machines.

Manual copy

You can also manually copy the OneGet binaries. For example, copy the entire E:\OneGet\oneget\src\out\PackageManagement folder you just built to your $env:Programfiles\WindowsPowerShell\Modules\PackageManagement\#onegetversion\

If you are running within PowerShellCore, similarily drop the PackageManagement folder to your $env:Programfiles\PowerShell\#psversion\Modules\PackageManagement\#onegetversion\,

or copy to /opt/microsoft/powershell/<psversion>/Modules/PackageManagement/#onegetversion/, if you are running on Linux or Mac.

Note: OneGet version number can be found from the PackageManagement.psd1 file.

Testing the code

> cd oneget
> cd Test
> & '.\run-tests.ps1' fullclr
> & '.\run-tests.ps1' coreclr

Understanding the OneGet code repository

OneGet is under rapid development, and so you get to see just how the sausage is being made. I try to keep the master branch clean and buildable, but my own working branch can get pretty damn wild and I make no bones about some of this. I work fast, I make big changes, and I try to keep my eye on the target.

Feel free to clone the repository, and check out the different branches:


There are currently three branches in the git repository:

Branch/Tag Purpose
master The master branch is where the daily builds of OneGet will be made from.
WMF5_RTM The WMF5_RTM tag is to mark the WMF 5.0 RTM release point.
TP5 The TP5 tag is to mark the TP5 release point.
wip The wip branch is where the current unstable and not-likely-working coding is taking place. This lets you see where I'm at before stuff actually hits the master branch. Fun to read, but really, the wild-west of code branches.

Contributing to OneGet

Contributions to the OneGet project will require the signing of a CLA -- contact @jianyunt for details...

In the immediate time frame, we won't be taking pull requests to the core itself, as we still have many masters at Microsoft to keep happy, and I have a lot of release process stuff I have to go thru to make them happy.

There are some exceptions to the where I can take Pull Requests immediately:

Pull Requests to the Package Providers are instantly welcome

Any unit tests, BVT tests or -Edge only features, we can take pull requests for as well

Docs, Wiki, content, designs, bugs -- everything gleefully accepted :D

Participating in the OneGet Community

I'm eager to work with anyone who wants to help shape the future of Package Management on Windows -- your opinions, feedback and code can help everyone.

Online Meeting

We have an online meetings. We will twitter the exact time as well as put a note on GitHub site. (everyone welcome!)

You can see archives of the previous meetings available on

All meeting notes are recorded under OneDrive PackageManagement
