Introduction

In my last article I showed you how easily Silverlight can interact with the HTML DOM. Not only you can execute JavaScript functions from your Silverlight application, but you can also call Silverlight methods from JavaScript. This functionality enables you to create very powerful applications.

As you already know Silverlight runs in a sandbox. This is a special “place” limited for security reasons. It is part of the browser, so Silverlight runs in the browser. Here are some of the limitations of Silverlight:

• You have no direct access to the local resources like printers.

Introduction

Silverlight helps for creating Rich Internet Applications (RIAs). It runs in the context of the browser. There is an isolated area, called sandbox, which holds the Silverlight application. But why is it necessary to restrict the Silverlight applications in such a way? The answer of this question is pretty simple - because of the security. Running such applications locally is dangerous. They may damage your computer or your data. So, there is a necessity to somehow restrict them. Thus, a Silverlight application runs in the sandbox.
