Questions tagged [silverlight-4.0]

Silverlight is Microsoft's cross-browser, cross platform plug-in for media experiences and rich interactive applications. The version 4 was released in April 2010.

Microsoft Silverlight is an application framework for writing and running rich Internet applications with emphasis on multimedia, animations, and graphics, with features and purposes similar to those of Adobe Flash. The run-time environment for Silverlight is available as a plug-in for most web browsers. While early versions of Silverlight focused on streaming media, current versions support multimedia, graphics and animation, and give developers support for CLI languages and development tools.

It is the standard for writing Windows Phone 7 applications and is being promoted for Line of Business (LoB) applications.

Platforms Supported

  • Silverlight 4 for Window (Chrome, Firefox, IE 6-9) & Mac (Firefox, Safari)
  • Windows Phone 7, Windows 8
