Migrating Azure Pipelines Deployments to GitHub Actions - yaml

Question

I have an Azure Pipeline build which builds NuGet packages on Windows, MacOS and Linux and a deployment job that then takes the NuGet packages built from the Windows image and publishes them to Azure Artefacts, GitHub packages and NuGet.
With GitHub actions, I have managed to build NuGet packages on Windows, MacOS and Linux but I don't know how to then create a deployment job as that feature doesn't exist. I think I need to create a new deployment job that is triggered from a successful build job, pick up the NuGet packages from the successful build and then push them. However, I don't see a trigger type that can do that.

Migrating Azure Pipelines Deployments to GitHub Actions
Indeed, there is no such multi-stage feature for Github action at this moment.
Just as you suspect, we could create a deployment job to deploy the artifact. We could try to create a new job which needs the existing build job, in the new job, download the artifacts and push them to azure artifact, github packages, nuget:
jobs:
job_1:
name: Build
job_2:
name: Deploy
needs: job_1
runs-on: windows-latest
steps:
- name: Download math result for job 1
uses: actions/download-artifact#v1
with:
name: xxx
You could check the Github action jobs.<job_id>.needs and the sample for some more details.
Hope this helps.
