微软新发布的silverlight入门包，包括了最新功能的演示和实作步骤，值得看看。
随Silverlight附赠的一个功能是在Firefox中无法运行，修改办法是：
Firefox中输入: about:config
设置dom.ipc.plugins.enabled为true
重启即可
[原因是由于sl4中元素引入了AllowDrop属性，和firefox的默认设置冲突]
以下是几个操作界面图

1、WCF RIA Services
2、打印
3、elevated trust when running outside the browser
4、implicit styling (making theming your application a lot easier), webcam and microphone support
5、MVVM模式和prism框架
