Insert a Silverlight-based application into a page
Microsoft Silverlight is a cross-browser, cross-platform plug-in for delivering rich interactive applications for the web. You can use programs such as Microsoft Expression Blend 2 or Microsoft Expression Encoder to create a Silverlight 1.0–based application for the web.
To insert a Silverlight-based application into a page
Open your website, and then open a web page from that website.
On the Insert menu, point to Media, and click Silverlight.
In the Insert Silverlight 1.0 dialog box, click Select Folder.
If the folder that you selected in the previous step contains more than one web page, in the Insert Silverlight 1.0 dialog box that appears, select the homepage of your Silverlight application, and click Select.
The folder that Expression Web adds to your website contains the imported assets for your Silverlight-based application. You can move and rename the imported folder, but you should not move or rename the contents of the imported folder. Otherwise, the Silverlight-based application may not work.
