This action sets up a [dotnet core cli](https://github.com/dotnet/cli) environment for use in actions by:

- optionally downloading and caching a version of dotnet by SDK version and adding to PATH
- registering problem matchers for error output
- setting up authentication to private package sources like GitHub Packages

# Usage

See [action.yml](action.yml)

Basic:
```yaml
steps:
- uses: actions/checkout@master
- uses: actions/setup-dotnet@v1
  with:
    dotnet-version: '3.1.x' # SDK Version to use; x will use the latest version of the 3.1 channel
- run: dotnet build <my project>
```
