Can Ruby import a .NET dll?

using System;
using System.IO;

namespace ComLib
{
    public class LogWriter
    {
        public void WriteLine( string line )
        {
            using( var log = new StreamWriter( File.OpenWrite( @"c:log.file" ) ) )
            {
                log.WriteLine( line );
            }
        }
    }
}

[assembly: ComVisible( false )]

[ComVisible( true )]
public class LogWriter ....

require 'win32ole'

lib = WIN32OLE.new('ComLib.LogWriter')
lib.WriteLine('calling .net from ruby via COM, hooray!')
