Subject: Parsing Command Line Arguments in .NET || Topic: Add basic arg validation about bytefish.de HOT 2 CLOSED

Thanks for the feedback. Great, that it's useful. 👍 Probably one could also add some options like passing a ParserOptions.Strict, so it either fails with an Exception for an empty option name or just ignores empty arguments. You could also think about returning a Parse Result instead of an out Parameter like:

public class ParseResult 
{
    public string[] Arguments { get; set; }

    public IReadOnlyList<CommandLineOption> Result { get; set; }

    public int[] ValidArguments { get; set; }

    public int[] InvalidArguments { get; set; }
}

Where ValidArguments and InvalidArguments could be the indices, that are problematic.

I see System.CommandLine is still in PREVIEW. Do you know by chance, what's the official recommendation by Microsoft for CLI applications?
