Question

我有一个ASPX Web应用程序，其中一个页面应该加载Silverlight应用程序。我遇到的问题是Silverlight应用程序不会出现在任何ASPX页面上，但会出现在HTML页面上。这是使用VS'ASP.Net开发服务器。

当我添加SL应用程序时，VS创建了两个测试页面。如上所述，HTML页面可以工作，但ASPX测试页面没有。我已经将HTML页面的副本创建为ASPX页面，但它不起作用。通过Fiddler和Silverlight Spy运行它表明没有尝试下载Silverlight应用程序（Fiddler中没有行）或甚至启动Silverlight插件（右键单击页面上的任何位置都不显示Silverlight上下文菜单）。加载ASPX页面后，IE或Firefox不会报告页面加载或JavaScript错误

我尝试过<object>方法和<asp:silverlight>。没有给我任何快乐。

以下是VS生成的HTML页面的代码：

以下是VS生成的测试ASPX的代码：

发现问题：

我们有一个应用于ASPX页面的主题。在CSS内部，存在以下条目：

OBJECT {

DISPLAY: none

}

删除此违规风格后，Silverlight应用程序出现了。

我发现这是通过将ASPX呈现的HTML复制到一个新的HTML页面，发现它也不起作用！我能找到的唯一区别是标题中包含的CSS。删除此条目后，Silverlight应用程序将起作用。使用IE8开发人员工具，我仔细研究了应用的CSS，发现上面的规则应用于我的对象条目。

无论如何，谢谢你们。在Silverlight.Net论坛上向绅士大声呼喊;当我向他们发布相同的问题/问题时，他们真的非常渴望和帮助我

ASPX页面中的Silverlight没有加载，但是在HTML中
