There are 2 different NuGet credential providers; Gen 1, and Gen2.
This was the first effort by the NuGet team to introduce credential providers. The interface is simple, they print some JSON to stdout with a status code. The NuGet team overlooked .NET Core support, because the discovery process assumed they would be named CredentialProvider.*.exe.
Paket added Gen 1 provider support, and in addition supported .NET Core by changing the discovery process to include CredentialProvider.*.dll, running those under .NET Core. With that said, there are no credential providers I am aware of that adopt this mechanism.
The NuGet team realised they needed .NET Core support, and cross-plat support. At the same time, they wanted to tackle NuGets plugin architecture, plugin trust and more. The result was a more complex system, where there is a JSON protocol over stdin/stdout with handshakes and all sorts.
Paket has yet to adopt Gen 2 credential providers.
| Provider | Gen | Windows Support | macOS Support | ADO Distributed* | NuGet Client Support | Paket Support |
|---|---|---|---|---|---|---|
| CredentialProvider.VSS | Gen 1 | ✔️ | ❌ | ❌ | Going soon | ✔️ |
| CredentialProvider.Microsoft | Gen 2 | ✔️ | ✔️ | ✔️ | ✔️ | ❌ |
| CredentialProvider.Gen2Support | Gen 1 | ✔️ | ✔️ | ❌ | Going soon | ✔️ |
- ADO Distributed means that it is what is shown on the Artifacts page under "Connect to feed..." dialog.
This package acts as a shim by implementing a Gen 1 provider, that talks to Gen 2 providers. It has knowledge of the Azure Artifacts Credential Provider so that under non-Windows it can ask you to run the appropriate command to authenticate.
This shim solves the problem of adopting Gen 2 pacakges with Paket while the eco-systems align.
Be sure to have installed the Azure Artifacts Credential Provider, under $HOME/.nuget/plugins.
- Ensure the following directory exists
%HOME%\AppData\Local\NuGet\CredentialProviders\Paket.CredentialProvider.Gen2Support, creating any missing directories as necessary. - Download the latest
CredentialProvider.Gen2Support.zipfrom the releases tab and unzip the contents of into it.
- Create a folder named
CredentialProvidersunder:$HOME/.local/share/NuGet - Download the latest
CredentialProvider.Gen2Support.zipfrom the releases tab and unzip the contents of into it.
