Automatically setup .NET environment for actively used SDK versions

Usage

The action is typically used in combination with which-dotnet to keep the CI environment up-to-date with evolving .NET versions used in your repository projects.

If no previously persisted JSON file is provided, automatic discovery of used .NET SDK versions will be performed using which-dotnet.

It's recommended you set up a separate workflow that keeps a dotnet.json file up-to-date to speed-up your builds by avoiding dynamic discovery on every build.

Assuming your repository has the dotnet.json file in its default location (under ./.github), or has no versions file at all:

on:
  push:

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - name: 🤘 checkout
        uses: actions/checkout@v4

      - name: ⚙ dotnet
        uses: devlooped/actions-dotnet-env@v1

      - name: 🙏 build
        run: dotnet build

If you use a different location for the versions file:

  - name: ⚙ dotnet
    uses: devlooped/actions-dotnet-env@v1
    with:
      versions: ./dotnet-versions.json

In order to bootstrap the initial dotnet.json file, you can run the dotnet-env tool with the -o parameter, which initializes it at the default location ./.github/dotnet.json.
