Sharepoint 2010 silverlight web part not available

I have developed a silverlight application with WCF-RIA services and is working fine. I have to deploy this application on a Sharepoint 2010 site.

I am new to Sharepoint 2010. I am having "Full Control" on the site. But when I am in edit mode, not able to see "Media and Content" category which is having "Silverlight" web part.

New web page -> edit page -> Insert -> Web part.

This may be a simple setting issue. Can so开发者_C百科meone please help. Thanks.

Along with whatever Thorsten has mentioned, I had to make another setting. Providing access to the web parts which was preventing users from viewing all the web parts

you've to activate the "SharePoint Server Publishing Infrastructure" Site Collection Feature. After activating all the Silverlight WebParts are available.
