为什么Silverlight播放器会误导用户,认为他可以"选择是否下载并安装更新"？

Question

我有一个silverlight应用程序,用户可以在浏览器外安装.

当右键单击,并期待在更新面板,它被设置为"检查更新,并让我选择是否下载并安装:

然而,用下面的代码,我的应用程序检测并下载新版本的自动,和新版本可于下次启动应用程序,无需任何用户互动:

App.xaml.cs:

private void Application_Startup(object sender, StartupEventArgs e)
{
    this.RootVisual = new BaseApp();
    if (Application.Current.IsRunningOutOfBrowser)
    {
        Application.Current.CheckAndDownloadUpdateAsync();
        Application.Current.CheckAndDownloadUpdateCompleted += new CheckAndDownloadUpdateCompletedEventHandler(Current_CheckAndDownloadUpdateCompleted);
    }
}

void Current_CheckAndDownloadUpdateCompleted(object sender, CheckAndDownloadUpdateCompletedEventArgs e)
{
    if (e.UpdateAvailable)
    {
        //an new version has been downloaded and silverlight version is the same
        //so user just has to restart application
    }
    else if (e.Error != null &&
        e.Error is PlatformNotSupportedException)
    {
        //a new version is available but the silverlight version has changed
        //so user has to go to new website and install the appropriate silverlight version
    }
    else
    {
        //no update is available
    }
}

这恰好是我想要的特定应用程序,但是:

这不是误导用户,因为Silverlight播放器让他相信他将能够"选择是否下载和安装更新",实际上,在他不知情的情况下下载和安装更新？

Silverlight不会误导用户.此配置对话框不适用于您的应用,更新适用于Silverlight本身,而不适用于您的应用.
