我为对象创建了一个类：

[ComVisible(true)]
class BrowserClient
{
    private MainWindow owner;

    public string id = "browser-client";

    public BrowserClient(MainWindow owner)
    {
        this.owner = owner;
    }

    public void sendMessage(string date)
    {
        owner.OnReceiveMessage(date);
    }
}

请注意ComVisible属性.

但是当我在Window_Loaded事件中设置ObjectForScripting属性时：

webBrowser.ObjectForScripting = new BrowserClient(this);

我得到以下(非常混乱)异常：

An unhandled exception of type ‘System.ArgumentException’ occurred in
PresentationFramework.dll

Additional information: The object type is not visible to COM. You
need to set ComVisibleAttribute attribute to True.

不用说,我很困惑.这里发生了什么？

更新：值得一提的是,我在Windows 8.1上使用.NET 4.0和Visual Studio 2013 Express for Desktop.
