I know there could be restriction for Silverlight application to access local file system and resources. Is it possible for a browser based silver light application made full trustable at client local machine by doing some settings in client machine?

Thank you so much for your reply.

Thank you for your reply. Are you saying that we need to host a webbrowser control inside our WPF application and programatically load the Silverlight control at runtime?

"but only inside a web browser instance running inside the WPF application" means?

I have a user control which is created in Silverlight. Can I include the same user control in WPF? Please reply.
