atch out, Adobe — Silverlight 4 is here to give you a run for your 
money. Web site designers and developers alike can find much to 

be excited about in Microsoft’s answer to Adobe Flash. As we tell you in 
more detail in the Introduction to this book, Silverlight 4 is one of a new 
family of Web site applications that provide graphics, animation, audio, 
and video — all the features necessary for the kind of rich user experience 
people have come to expect on the Web. These applications are called Rich 
Internet Applications (RIA). Adobe Flash was one of the first in the RIA arena; 
more recently, Microsoft made its entry into this space with the launch of 
Silverlight.

In this chapter, we give you an overview of what Silverlight is, what it can do, 
and the tools you need to develop Silverlight applications.

Obtaining and Running Silverlight

As does Adobe Flash, Silverlight runs as a plug-in within the browser and 
needs to be installed the first time any Silverlight application is run. A plug-in 
is a piece of software that is not part of the Web browser but can be added to 
it to run additional applications. When a user visits a Web site that needs the 
Silverlight plug-in, the Web browser will prompt the user to install it.
