c#創建activex問題-有解無憂

Hi:
我用c#vs2017創建了一個activex 64位dll工程（非any cpu），編譯通過，在IE瀏覽器html網頁上運行正常，但是在IE 瀏覽器F12除錯html代碼時提示沒有加載activex。作業系統是Win10 64位，IE11.謝謝各位。
代碼如下：

.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Runtime.InteropServices;
namespace ClassLibrary1
{
    [ProgId("DemoClassLibrary1.HelloWorld")]
    [ClassInterface(ClassInterfaceType.AutoDual)]
    [Guid("731632A9-05F4-4B8E-A34E-BCA8168843B9")]
    [ComVisible(true)]
    public class Class1
    {
        [ComVisible(true)]
        public String SayHello()
        {
            return "helloworld";
        }
    }
}

運行結果，分兩種情況：
1.直接運行，正常：
*.使用IE打開html網頁，正常。

2.使用IE F12除錯html，例外：
*.打開IE
*.按F12
*.輸入本地html檔案地址
*.提示"Object doesn't support property or method 'SayHello'",html的object控制元件(activex控制元件)沒有加載成功。

問題：
為什么沒有加載成功，我需要使用IE F12除錯html代碼。
