Why would I do this?

omg.cs

using System;
using System.Threading.Tasks;
using EdgeJs;

class Program
{
    public static async Task Start()
    {
        var func = Edge.Func(@"
            return function (data, callback) {
                callback(null, '');
            }
        ");

        string str = await func());
    }

    static void Main(string[] args)
    {
        Start().Wait();
    }
}
