Simply Silverlight is very easy to use. If you have a Silverlight .xap file you want to include in a post or page, follow this simple recipe.

1. Install Simply Silverlight as per the instructions above. Be sure to activate the plugin after you install it.
2. Place a copy of your .xap file in the /ClientBin directory off the root of your website. This is the plugin’s default storage location for Silverlight .xap files.
3. Create or edit any post or page on your site. In the location you want the Silverlight application displayed, insert the WordPress shortcode, [simply-silverlight xap=filename.xap]. The shortcode provides several attributes to refine the output. All of them are optional except the xap attribute. Here they are:
   xap – The name of the Silverlight .xap file. This attribute is required. path – The location of the .xap file relative to the root of the site. Can be an absolute URL. width – The Width attribute of the OBJECT tag. [Valid values: 0-9999] height – The Height attribute of the OBJECT tag. [Valid values: 0-9999] display – The CSS Display property of the DIV tag's Style attribute. [Valid values: inline, block or list-item] float – The CSS Float property of the DIV tag's Style attribute. [Valid values: left or right] style – The Style attribute of the DIV tag. Takes precedence over the Display and Float properties. [Valid values: any valid Style markup] background - The Background color of the OBJECT tag. [Valid values: any valid HTML color value, default is white] version - The minimum runtime version of Silverlight required by the control. [Valid values: 3.0.50106.0, 4.0.60531.0 or any valid version number] autoupgrade - The existing Silverlight runtime will attempt to upgrade itself if necessary. [Valid values: true or false] onerror - Define an error handler to call when the Silverlight plug-in encounters an error. initparams – These are user-defined initialization parameters for the control.
