.NET Core 3.0 の目玉の single exe を preview5 で試してみた

.NET Core 3.0 の目玉の single exe がどれくらいのサイズになるのか興味があって、 preview5 で試してみた.
Hello World が 67MB だった.
出来た EXE を .NET Core 3.0 preview が入っていない別のマシンに持っていって動くことは確認できたが、Assembly trimmer 待ちかなあと思わされるサイズである.

namespace ConsoleApp1
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Hello World!");
        }
    }
}
