Microsoft Silverlight 5.1

Silverlight is a powerful development tool for creating engaging, interactive user experiences for Web and mobile applications. It is compatible with multiple browsers, devices and operating systems, bringing a new level of interactivity wherever the Web works. It helps you to create business applications that give users richer, deeper interactivity using the skills and tools developers already know and that work the same everywhere–without the usual IT hassle of deploying across multiple OS's and browsers.
