# >_ dotnet-env

Automatically setup .NET environment for actively used SDK versions 

## Usage

The action is typically used in combination with [which-dotnet](https://github.com/marketplace/actions/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](https://github.com/marketplace/actions/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:

```yml

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:

```yml

  - 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](https://www.nuget.org/packages/dotnet-env) 

tool with the `-o` parameter, which initializes it at the default location `./.github/dotnet.json`.
