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: '3.1.100' # SDK Version to use.
- run: dotnet build <my project>
```
Matrix Testing:
```yaml

- name: Create the package
run: dotnet pack --configuration Release <my project>
- name: Publish the package to GPR
run: dotnet nuget push <my project>/bin/Release/*.nupkg
# Authticates packages to push to Azure Artifacts
- uses: actions/setup-dotnet@v1
with:
source-url: https://pkgs.dev.azure.com/<your-organization>/_packaging/<your-feed-name>/nuget/v3/index.json
env:
NUGET_AUTH_TOKEN: ${{secrets.AZURE_DEVOPS_PAT}} # Note, create a secret with this name in Settings
- name: Publish the package to Azure Artifacts
run: dotnet nuget push <my project>/bin/Release/*.nupkg

## Environment Variables to use with dotnet
Some environment variables may be necessary for your particular case or to improve logging. Some examples are listed below, but the full list with complete details can be found here: https://docs.microsoft.com/en-us/dotnet/core/tools/dotnet#environment-variables
- DOTNET_NOLOGO - removes logo and telemetry message from first run of dotnet cli (default: false)
- DOTNET_CLI_TELEMETRY_OPTOUT - opt-out of telemetry being sent to Microsoft (default: false)
- DOTNET_MULTILEVEL_LOOKUP - configures whether the global install location is used as a fall-back (default: true)
