[Question] How to properly create an asynchronous command?

[MillzyDev]

I am using an API wrapper in a command declared with an attribute, the specific method I'm calling in the command is asynchronous. Upon executing the command, I get a blank statement in the console.

using Microsoft.VisualStudio.TestTools.UnitTesting;
using BeatSaverSharp;
using McMaster.Extensions.CommandLineUtils;
using System;
using System.ComponentModel.DataAnnotations;
using static PlaylistPrimeCLI.Helpers.BeatSaverHelper;

namespace PlaylistPrimeCLI.Commands
{
    [Command("create", Description = "Creates a new bplist from BeatSaver search queries")]
    internal class CreateCommand
    {
        [Option("-n|--name", Description="The name of your playlist")]
        [Required]
        public string Name { get; set; }

        private async void OnExecute(CommandLineApplication app)
        {
            var query = await Client.SearchBeatmaps(new SearchTextFilterOption // async method
            {
                NoodleExtensions = true,
                Chroma = true
            });

            Assert.IsNotNull(query);
            Console.WriteLine(query.BeatMaps[0].Key); // (bool value) nothing gets printed

            Console.WriteLine(Name); // nothing gets printed
        }
    }
}

Any guidance on resolving this issue is very much appreciated

Don't use async void. Use async Task instead. https://haacked.com/archive/2014/11/11/async-void-methods/
