Как вызывать методы из классов NET Framework в программе на VB6?

using System;
using System.IO;
using System.IO.Compression;
using System.Runtime.InteropServices;
 
namespace CoCOMWrapper
{
    [ComVisible(true)]
    [Guid("12345678-90AB-CDEF-1200-567890ABCDEF")]
    [InterfaceType(ComInterfaceType.InterfaceIsIDispatch)]
    public interface ICompressionWrapper
    {
        void CompressFile(string inputFile, string outputFile);
    }
 
    [ComVisible(true)]
    [Guid("12345678-90AB-CDEF-1211-567890ABCDEF")]
    [ClassInterface(ClassInterfaceType.None)]
    public class CompressionWrapper : ICompressionWrapper
    {
        public void CompressFile(string inputFile, string outputFile)
        {
            using (FileStream originalFileStream = new FileStream(inputFile, FileMode.Open, FileAccess.Read))
            using (FileStream compressedFileStream = new FileStream(outputFile, FileMode.Create, FileAccess.Write))
            using (GZipStream compressionStream = new GZipStream(compressedFileStream, CompressionMode.Compress))
            {
                originalFileStream.CopyTo(compressionStream);
            }
        }
    }
}
