impressive – wordpress knows how to handle silverlightplugins:

thanks to the plugins

• Simply Silverlight by David Wright

and

• PJW Mime Config by Peter Westwood

thank you guys!

Instructions:

• install the Plugins
• Add a new MimeType: “.xap” with “application/x-silverligth-app” using Mime Config (this will allow to upload .xap files to WordPress without messing with the PHP-code)
• Upload the .xap and remember the path to it (copy&paste FTW)
• Add the silverlight-applet using simply silverlights tag and the path you found in – that’s it
