I mark this as a Community Wiki.
Please clarify your intent. What do you mean by a Silverlight feature ?
Silverlight is a subset of WPF, but is intended for a Web application (i.e. running inside a Web browser, using the .NET framework provided by the browser plug-in), while WPF is meant for a desktop application (i.e. running outside of a browser, using the full .NET present on the disk).
(there is the notion of running WPF inside the browser, but that is still using the full .NET framework).
