XBAP with entity framework

Question

Hello,

I am trying to write a xbap application (WPF browser application). This application need to be very simple. It doesn't have services or logic and just reads data from database by using entity framework. However, I setup a reference to entity framework in my xbap app. It tells me that "that assembly does not allow partially trusted callers ".

Now I doubt my if my idea is even possible, since xbap will be deployed to user's machine (in IE) and my database is on server.

Thanks.
