Creating a Silverlight plug-in

The goal of creating a Silverlight plug-in is to host a Silverlight application.
This plugin can be created in at least two different ways.
One of these approaches is to use the Silverlight server control that’s part of the Silverlight 2 Software Development Kit (SDK).2
In general, if you’re an ASP.NET developer, this is the approach you’ll want to use.
But we’re going to discuss the specifics of a Silverlight plug-in while covering another approach. Another approach for creating a Silverlight plug-in enables you to deliver Silverlight content through any server technology.
You can use Silverlight along with a variety of technologies including PHP, JSP, ASP, and ASP.NET.
To get Silverlight to work with these technologies, you use the two steps covered in this section. The first step is to reference the required Silverlight utility file.
The second step involves writing the JavaScript that will create an instance of the Silverlight plug-in.
