When you first attempt to create a Silverlight project in Visual Studio 2008, you may be surprised to find there is no project template for it. To get it, you will need to install the Silverlight Tools for Visual Studio 2008 SP1. Be sure to install Service Pack 1 for Visual Studio 2008 before installing the Silverlight tools.
After the toolset is installed, you can will find the Silverlight project templates under the C# and VB.NET categories.
