If you write open source of .NET library, you can benefit from this post.

This post will use GitHub Actions workflow to CI/CD your open sourc.

It will cover:

• Auto increment version
• Build
• Run Test
• Push NuGet to nuget.org (future post may show how to push to GitHub packages)

It assumes you’re handling the project variations at the solution level using ‘Directory.Build.props’.

Setting this workflow is supper easy.
Follow these steps to complete it.

• Navigate to nuget.org
• Create API key

• Navigate to your GitHub repo.
• Add a secret named [NUGET_PUBLISH] for the nuget.org access key (you’d created).
• Select the ‘Actions’ tab
• Click ‘Set up this workflow’
• Replace the yaml content with the following yaml:
  within the yaml, replace the following parts:
  - BUILD_CONFIG: 6.0.x
  - INCLUDE_PRERELEASE: true
  - Check that the test pattern [**/*Tests] match your file structure.

    branches: [ master ]

      run: dotnet nuget push ./**/out/*.nupkg -k ${{ secrets.NUGET_PUBLISH }} -s https://api.nuget.org/v3/index.json --skip-duplicate --no-symbols true

That’s all.

I hope it was useful.

You can take a look at Event Source Backbone repo to see how to use it with nuget.org.
