This project provides a seamlessly integration of a [curated list](registry.json) of NuGet packages within the Unity Package Manager.

> DISCLAIMER: This is not an official service provided by Unity Technologies Inc.

## Installation

### Add scope registry (manifest.json)

In order to use this service you simply need to edit the `Packages/manifest.json` in your project and add the following scoped registry:

```json
{
"scopedRegistries": [
{
"name": "Unity NuGet",
"url": "https://unitynuget-registry.azurewebsites.net",
"scopes": [
"org.nuget"
]
}
],
"dependencies": {
"org.nuget.scriban": "2.1.0"
}
}
```

### Add scope registry (Package Manager UI)

Instructions:

```yaml
Name: Unity NuGet

Url: https://unitynuget-registry.azurewebsites.net

Scope(s): org.nuget
```

### Disable Assembly Version Validation

This step is necessary to ensure that binding redirects for [strongly named assemblies](https://learn.microsoft.com/en-us/dotnet/standard/assembly/strong-named) in NuGet packages resolve correctly to paths _within the Unity project_.

- In Unity 2022.2+, this is the [default behavior](https://forum.unity.com/threads/editor-assembly-loading-issues-unloading-broken-assembly-could-not-load-signature.754508/#post-8647791), so no action is required.
- For earlier Unity versions, uncheck "Project Settings > Player > Other Settings > Configuration > Assembly Version Validation"

### Verify installation

> 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 `unitynuget-registry.azurewebsites.net` registry.
> On Windows, this cache is located at: `%localappdata%\Unity\cache\npm\unitynuget-registry.azurewebsites.net`
>
> Cache locations by OS:

When opening the Package Manager Window, you should see a few packages coming from NuGet (with the postfix text `‎ (NuGet)`)

## Adding a package to the registry

This service provides only a [curated list](registry.json) 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 not `1.0.0-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](registry.json) file (don't forget to maintain the alphabetical order)

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.

## Compatibility

Only compatible with **`Unity 2019.1`** and potentially with newer version.

> NOTE: This service is currently only tested with **`Unity 2019.x, 2020.x, 2021.x, 2022.x, 2023.x and 6`**
>
> It may not work with a more recent version of Unity

## Docker

> Available in [ghcr (GitHub Container Registry)](https://github.com/xoofx/UnityNuGet/pkgs/container/unitynuget).
>
> Supported platforms:
>
> - linux/amd64
> - linux/arm64

Example of a basic docker-compose.yml file:

```yaml
services:
unitynuget:
image: ghcr.io/xoofx/unitynuget:latest
ports:
- 5000:80
volumes:
- ./unity_packages:/app/unity_packages
- ./registry.json:/app/registry.json # (Optional) You can have your own registry.json with a different package list than the one already included in the repository
```

There is a complete example with all available options in [examples/docker](examples/docker).

### Accessing a private NuGet feed from Azure DevOps

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











```

> **Note**: [The Azure DevOps PAT](https://learn.microsoft.com/en-us/azure/devops/organizations/accounts/use-personal-access-tokens-to-authenticate) must have Packaging (Read) permissions.

## FAQ

### **Where is hosted this service?**

On Azure through my own Azure credits coming from my MVP subscription, enjoy!

### **Why can't you add all NuGet packages?**

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.

Also currently the Package Manager doesn't provide a way to filter easily packages, so the UI is currently not adequate to list lots of packages.

### **Why does it require .NETStandard2.0?**

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.

### **How this service is working?**

This project implements a simplified compatible NPM server in C# using ASP.NET Core and converts NuGet packages to Unity packages before serving them.

Every 10 minutes, 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.
