This is a GitHub Action meant to be used as a composite action within an existing workflow. This action encapsulates setting up .NET SDK, MSBuild path (on Windows only), and NuGet CLI in one step. Each is optional, but I'd argue if you are only using one of these then just use the actual action.

The action encapsulates the following other actions:

• actions/setup-dotnet
• microsoft/setup-msbuild
• NuGet/setup-nuget
• darenm/Setup-VSTest

You can use this composite Action in your own workflow by adding:

on: [push]

jobs:
  hello_world_job:
    runs-on: ubuntu-latest
    name: A job to say hello
    steps:
      - uses: actions/checkout@v4
      - id: foo
        uses: timheuer/bootstrap-dotnet@v2
        with:
          dotnet-version: 8.0.x
      - run: echo random-number ${{ steps.foo.outputs.random-number }}
        shell: bash

This action uses the following defaults:

• dotnet-version: 8.0.x
• MSBuild: latest (meaning the latest version installed on an agent)
• NuGet: latest (meaning the latest CLI version)
• VSTest: false (meaning VSTest.Console is not setup for you)

You can disable any step of these by opting out in your usage.

Example, to skip NuGet setup

on: [push]

jobs:
  hello_world_job:
    runs-on: ubuntu-latest
    name: A job to say hello
    steps:
      - uses: actions/checkout@v4
      - id: foo
        uses: timheuer/bootstrap-dotnet@v2
        with:
          dotnet-version: 8.0.x
          nuget: 'false'
      - run: echo random-number ${{ steps.foo.outputs.random-number }}
        shell: bash
