Publishing .NET Packages to NuGet.org with an API Key

Описание и применение

Автоматизированный процесс публикации .NET‑пакетов в NuGet.org с безопасным хранением ключа API в GitHub Actions.

Automating the publishing of .NET libraries to NuGet.org while keeping API keys secure.

Automated, secure publishing of .NET packages with minimal manual intervention and reduced risk of credential leakage.

Create a NuGet API key with Push scope and optional package pattern
Store the API key as a GitHub Actions repository secret (e.g., NUGET_API_KEY)
Add a workflow step that runs dotnet nuget push with --api-key "$NUGET_API_KEY" and --source https://api.nuget.org/v3/index.json
Optionally include --skip-duplicate to avoid failures on reruns

never commit the API key into the repository

The basic command is: dotnet nuget push <PACKAGE_FILE> --api-key <YOUR_API_KEY> --source https://api.nuget.org/v3/index.json
