Get current method name from async function?

Question

Is there anyway to get the current method name from inside an async function?

I\'ve tried:

System.Reflection.MethodInfo.GetCurrentMethod();

I came across the same issue recently for my log message and the answers here helped. I am sharing my code in case it can help others with their questions.

using System.Runtime.CompilerServices;

namespace Foo.Services
{
    public interface ILogFormatter
    {
        public string FormatMessage(LogType logType, string details, [CallerMemberName] string caller = "");
    }


    public enum LogType
    {
        Debug,
        Information,
        Warning,
        Error
    }

    public class LogFormatterOptions
    {
        public string Subject { get; set; }
    }

    public class LogFormatter : ILogFormatter
    {
        public LogFormatter(LogFormatterOptions options)
        {
            Subject = options.Subject;
        }

        public string Subject { get; set; }

        public string FormatMessage(LogType logType, string details, [CallerMemberName] string caller = "")
        {
            return $"{Subject} - {logType}: caller: {caller} - {details}";
        }
    }
}

This is how this method is called and it works for both async and synchronized methods. Note that I am not passing value for the caller input & it picks up the caller method name.

 logger.LogInformation(logFormatter.FormatMessage(LogType.Information, ""));
