Download instructions

Please cut and paste the code found below and place it in $IP/extensions/ExtensionName/ExtensionName.php. Note: $IP stands for the root directory of your MediaWiki installation, the same directory that holds LocalSettings.php.

Installation

1. Copy the code into a file (e.g. Silverlight.php)
2. Save the file in the extensions directory of your mediawiki folder
3. Add the line require_once("$IP/extensions/Silverlight.php"); to your LocalSettings.php file (The name of your file is case sensitive!)
4. If you don't already have it, add the lines $wgFileExtensions[] = 'xap'; $wgEnableUploads = true;

to your LocalSettings.php file.

Now you can use the extension with <silverlight>...</silverlight> in the wiki
