[API Proposal]: Process.RunAndCaptureLinesAsync for reading output lines streaming

[WeihanLi]

Background and motivation

Since we've introduced some new APIs for Process

• New Process APIs #125838
• Add ProcessOutputLine struct and Process.ReadAllLinesAsync #126987

wondering that maybe we could also add static methods Process.RunAndCaptureLinesAsync likes Process.RunAndCaptureTextAsync to simplify the read process output lines as a stream

API Proposal

namespace System.Diagnostics;

public class Process
{
    public static IAsyncEnumerable<ProcessOutputLine> RunAndCaptureLinesAsync(string fileName, IList<string>? arguments = null, CancellationToken cancellationToken = default);
    public static IAsyncEnumerable<ProcessOutputLine> RunAndCaptureLinesAsync(ProcessStartInfo startInfo, CancellationToken cancellationToken = default);
}

API Usage

await foreach (var line in Process.RunAndCaptureLinesAsync("dotnet", ["--info"]))
{
    ConsoleHelper.WriteLineWithColor(line.Content, line.StandardError ? ConsoleColor.Red : ConsoleColor.Green);
}
