This should get you started.

using System.Runtime.InteropServices;

namespace InteractorHint
{
    interface TestInterface
    {
        void WriteHints(string hint);
    }
}


namespace InteractorHint
{
    [ComVisible(true)]
    [Guid("TODO:SET-YOUR-GUID")]
    interface ITestCom
    {
        [DispId(1)]
        void WriteHints(string hint);
    }
}


namespace InteractorHint
{
    [ComVisible(true)]
    [ClassInterface(ClassInterfaceType.None)]
    [ComDefaultInterface(typeof(ITestCom))]
    [Guid("TODO:SET-YOUR-GUID")]
    public class Test : TestInterface, ITestCom
    {
        public Test()
        {
        }

        public void WriteHints(string strHint)
        {
            Console.WriteLine(strHint);
        }
    }
}
