You can use it anywhere, even locally, for free. The example in the post uses the .NET 10 file-based app feature we added support for today, so if you want to try the same functionality locally, you can do something like this:

  # Create a minimal .NET 10 file-based app
  echo 'Console.WriteLine("Hello HN");' > Hello.cs

  # Build an OCI image using the .NET CNB
  pack build hello-hn --builder heroku/builder:24

  # Run it with Docker
  docker run --rm -it --entrypoint hello hello-hn

  # Output:
  Hello HN
