Moonlight 2.0 Beta 1 Released – Open Source Implementation of Silverlight

Written By Sam on 19 August 2009

Moonlight is an open source implementation of Silverlight which is primarily meant for Linux and other Unix/X11 based operating systems. Moonlight 2.0 Beta 1 is released and is now feature complete. With this you can view all the Silverlight 2.0 sites. As this is a beta version you should only use this plugin on trusted sites on non-production computers.


The API implemented by Moonlight 2.0 is a slight superset of Microsoft Silverlight 2.0 as it contains a few of the Silverlight 3.0 APIs also.

Features From Silverlight 3.0 Supported in Moonlight 2.0

  • Easing functions
  • SaveFileDialog
  • MultiScaleImage 3.0 API enhancements
  • MediaStreamSource now supports PCM audio data, RGBA and YV12 video data.
  • WriteableBitmap is supported which can be used for your Quaking needs.
