Fixed to be able to use ’shell: dotnet run {0}'

[hanachiru]

Summary

Since .NET10 Preview 4, it is possible to run a standalone .cs file directly.

$ ls
app.cs
$ dotnet run app.cs

ref: https://devblogs.microsoft.com/dotnet/announcing-dotnet-run-app/

So I would like to write the following code.

- uses: actions/setup-dotnet@v4
  with:
    dotnet-version: "10.0.x"
    dotnet-quality: "preview"
- name: Sandbox
  shell: dotnet run {0}
  run: |
    Console.WriteLine("Hello, world!");

But I found that it only works if the extension is .cs.

$ dotnet run sample.cs    
Hello, World!
$ dotnet run sample2
Couldn't find a project to run. Ensure a project exists in /Users/hanachiru/Sandbox, or pass the path to the project using --project.

So I added the extension .cs if shellCommand is dotnet.

Changes

• If the shellCommand is dotnet, add the extension .cs.

Note

I would like to discuss with the reviewer whether to add ["dotnet"] = "run {0}" to the _defaultArguments.

runner/src/Runner.Worker/Handlers/ScriptHandlerHelpers.cs

Lines 13 to 21 in acf3f2b

	private static readonly Dictionary<string, string> _defaultArguments = new(StringComparer.OrdinalIgnoreCase)
	{
	["cmd"] = "/D /E:ON /V:OFF /S /C \"CALL \"{0}\"\"",
	["pwsh"] = "-command \". '{0}'\"",
	["powershell"] = "-command \". '{0}'\"",
	["bash"] = "--noprofile --norc -e -o pipefail {0}",
	["sh"] = "-e {0}",
	["python"] = "{0}"
	};
