Question

除了向IIS添加these文件类型并将.NET框架4.0安装到Web服务器之外，还需要做些什么才能使Hello Word Silver Light Web应用程序正常工作？是否需要单独的Silverlight安装？

虽然我在本地部署时网站正常工作，但在部署到远程Web服务器后，我收到以下错误：

Line: 54
Error: Unhandled Error in Silverlight Application 
Code: 2104    
Category: InitializeError       
Message: Could not download the Silverlight application. Check web server settings

我通过生成的html页面访问xap文件：

我是否必须安装一些Silverlight服务器组件？

Answer 1

除MIME类型外，您是否检查过内容过期设置并执行权限？

关于该错误代码的快速谷歌出现了这篇文章： http://weblogs.asp.net/javiervillarreal/archive/2008/06/14/silverlight-error-2104-could-not-download-the-silverlight-application-in-iis6.aspx

Answer 2

尝试直接请求.XAP文件。这将有助于将隐藏的Silverlight错误排除在等式之外：

http://myserver/directories/blah/myapplication.xap

Answer 3

您是如何加载Silverlight文件的？您使用的是ASP.NET Silverlight控件，Silverlight JavaScript调用还是使用了对象标记？为了删除ASP.NET和JavaScript作为可能的问题来源，您可能希望尝试从常规html文件中的对象标记加载它。

Answer 4

将IIS中虚拟文件夹的版本与您正在部署的应用程序的框架版本进行比较，以确保它们匹配。

将Hello World Silverlight应用程序部署到IIS5，Win XP
