This project provides a seamlessly integration of a curated list of NuGet packages within the Unity Package Manager.
Important
DISCLAIMER: This is not an official service provided by Unity Technologies Inc.
Note
Feed provided by OpenUPM.
In order to use this service you simply need to edit the Packages/manifest.json
in your project and add the following scoped registry:
{
"scopedRegistries": [
{
"name": "Unity NuGet",
"url": "https://unitynuget-registry.openupm.com",
"scopes": [
"org.nuget"
]
}
],
"dependencies": {
"org.nuget.scriban": "2.1.0"
}
}
Instructions: https://docs.unity3d.com/Manual/class-PackageManager.html
Name: Unity NuGet
Url: https://unitynuget-registry.openupm.com
Scope(s): org.nuget
Important
In Unity 2022.2+, this is the default behavior, so no action is required.
This step is necessary to ensure that binding redirects for strongly named assemblies in NuGet packages resolve correctly to paths within the Unity project.
For earlier Unity versions, uncheck Project Settings > Player > Other Settings > Configuration > Assembly Version Validation
.
Warning
WARNING: If you are encountering weird compilation errors with UnityNuGet and you have been using UnityNuGet already,
it could be that we have updated packages on the server, and in that case, you need to clear the cache containing
all Unity NPM packages downloaded from the registry.
On Windows, this cache by default is located at: %LOCALAPPDATA%\Unity\cache\npm
Cache locations by OS: https://docs.unity3d.com/Manual/upm-cache.html
When opening the Package Manager Window, you should see a few packages coming from NuGet (with the postfix text (NuGet)
)
This service provides only a curated list of NuGet packages.
Your NuGet package needs to respect a few constraints in order to be listed in the curated list:
- It must have non-preview versions (e.g
1.0.0
but not1.0.0-preview.1
). - It must provide at least
.NETStandard2.0
(and optionally.NETStandard2.1
) assemblies as part of its package.
You can send a PR to this repository to modify the registry.json file (don't forget to maintain the alphabetical order and format).
You also need to specify the lowest version of your package that has support for .NETStandard2.0
upward so that other packages depending on your package have a chance to work with.
Beware that all transitive dependencies of the package must be explicitly listed in the registry as well.
Note
- We reserve the right to decline a package to be available through this service.
- The server will be updated only when a new version tag is pushed on the main branch.
Only compatible with Unity 2019.1
and potentially with newer version.
Note
This service is currently tested with Unity 2019.x, 2020.x, 2021.x, 2022.x, 2023.x and 6000.0.x
.
It may not work with a more recent version of Unity.
To have more control of the server, it is recommended to host the service on your own. This way you can decide which specific packages to include in the registry.json file which makes the server lighter.
This project publishes a Docker image in ghcr.io that can be consumed to create a container and host it as you wish:
There is a complete example with all available options in examples/docker.
Note
The Azure DevOps PAT must have Packaging (Read)
permissions.
As documented in the example, it is possible to provide a custom NuGet.Config file.
To add a private feed, the following fields must be filled in:
<?xml version="1.0" encoding="utf-8"?>

<add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />

It is hosted by OpenUPM.
The reason is that many NuGet packages are not compatible with Unity, or do not provide .NETStandard2.0
or .NETStandard2.1
assemblies or are not relevant for being used within Unity.
Since 2019.1.x, Unity is compatible with .NETStandard2.0
and it is the .NET profile that is preferred to be used.
Having a .NETStandard2.0
for NuGet packages for Unity can ensure that the experience to add a package to your project is consistent and well supported.
As of Unity 2021.x it also supports .NETStandard2.1
so packages providing this target will be compatible with this version of Unity or newer.

This project implements a simplified compatible NPM server in C# using ASP.NET Core and converts NuGet packages to Unity packages before serving them.
At a threshold defined by UpdateInterval
(10 minutes by default), packages are updated from NuGet so that if a new version is published, from the curated list of NuGet packages, it will be available through this service.
Once converted, these packages are cached on the disk on the server.
