【IT168 技术文档】在前文<<初识Silverlight 4及其架构 >>谈到要从多个方面来了解：Silverlight的原理，处理周期，部署，安全性，伸缩性，分布式计算能力，容错能力，等等等等。这篇从原理的角度来看Silverlight 4架构相关的一些事情。
浏览器的插件
前文已经介绍过，整个Silverlight平台中包括一个安装器。这个安装器负责将浏览器插件安装上，并在客户浏览器那里搭建起运行Silverlight程序的基础环境。初次浏览Silverlight内容的客户必须先安装一个浏览器插件。安装了插件之后，插件安装程序向IE, Firefox等浏览器注入了插件。我们可以在浏览器中的扩展管理中看到，如图1和图2：

同时我们可以看到文件夹C:\Program Files\Microsoft Silverlight\4.0.50826.0建立了。其中的文件有：
驱动器 C 中的卷没有标签。 卷的序列号是 A474-0C97
