Its main purpose is to allow the creation of rich Internet applications.

Silverlight brings many features for developers, providing advanced tools for improving the playback performance, creating effects for animations and other graphical content and enhancing video quality. Therefore, you can benefit from the advantages and powerful features of the Silverlight technology, in order to create engaging Web, mobile and desktop media applications. This package is designed to extend the functionality of Visual Studio 2010 SP1, allowing you to develop applications for Silverlight using the C# or Visual Basic programming languages. The developer runtime component comes with error notifications that come in handy during the debugging process. The Silverlight 5 developer runtime, the Silverlight SDK, the Microsoft WCF RIA Services V1.0 SP2 and the Service Pack 1 for both Visual Studio 2010 and Visual Web Developer Express 2010 are included in the installer. Therefore, tooling for the Silverlight development environment in Visual Studio 2010 can only be obtained by installing it separately. While the 2012 version of Visual Studio already includes the most recent Silverlight tools, VS 2010 SP1 users do not benefit from the same advantage. It is designed to provide you with a simple solution for developing Silverlight applications using tools that you are already familiar with. Microsoft Silverlight Tools for Visual Studio 2010 SP1 is a package that can be used for adding Silverlight support for Visual Studio 2010 SP1 or Visual Web Developer 2010 Express SP 1.
