Connecting to a SQL Server from Windows Phone 7

I have a concept for a WP7 app but I need to establish a connection to a SQL Server from the app. Problem is I cant the method to do this in the the 4.0 framework. I know how to do this in a desktop app but I dont have the same methods available to me when developing开发者_如何学运维 a windows 7 phone app. Anyone know how to do this? If the concept is wrong can you direct me to how it should be done?

Silverlight (either on a phone, or a browser) simply can not make such network connections. You're going to need a server to talk to, likely with WCF

Doesn't look like you can at the moment -

It would be a better practice to front your database server with some kind of web service as exposing a database directly to the internet is generally considered too much exposure for your database.
