Silverlight for WordPress allows a WordPress user to specify a Silverlight application (XAP) to embed within their content easily.
Microsoft Silverlight is a browser plugin for enabling rich internet and media applications. This plugin makes it easy for WordPress content authors to add Silverlight applications/content to their blog posts and/or pages using a simple command to specify the location of the Silverlight application (XAP file) as well as the width, height and minimum version required for the runtime.
Special contributor note: Juergen Oberngruber and Peter Loebel had created beta versions of a WordPress plugin that inspired this updated version. Credit goes to them for taking the first ventures in this path!
