🏃 dotnet-run

Runs a C# file using .NET 10+

Usage

- name: 🏃 C#
  uses: devlooped/dotnet-run@v2
  with:
    # If args has newlines, it will be properly quoted/escaped
    args: |
      --message
      Hi "kzu", I can even mix 'single' quotes
    # Script can be an inline C# script, including nuget packages
    script: |
      #:package Humanizer@2.*
      using Humanizer;
  
      var date = DateTime.Parse("${{ github.event.inputs.date }}");
      var elapsed = DateTime.Now - date;
  
      if (elapsed.TotalSeconds > 0)
          Console.WriteLine($"It's been {elapsed.Humanize()} since {date.Humanize()}");
      else
          Console.WriteLine($"Still {elapsed.Negate().Humanize()} until {date.Humanize()}");

You can also specify a file to run:

- name: 🏃 C#
  uses: devlooped/dotnet-run@v2
  with:
    file: ./script.cs

The file does not need to have a shebang, but if it does, it will be ignored, since this action will always run the file using dotnet run.

If you give the step an id, you can use the output generated by the script in subsequent steps:

- name: 🏃 C#
  id: runcs
  uses: devlooped/dotnet-run@v2
  with:
    script: |
      Console.WriteLine("Hello world");

- name: 👀 output
  # will print "Hello world"
  run: echo "${{ steps.runcs.outputs.output }}"

The action will automatically install .NET 10+ SDK as needed.
