Hey! Some of you might have red the book "Head first C#."
I was looking for some help on the Service-based Datebase (page 52) as I try to open it, it come up with the following error: Connections to SQL Server files (*.mdf) require SQL Server Express 2005 to fuction properly. Please verity the intallation of the component or download from the URL: bla bla bla.
The thing is... I've been downloading it, and upgraded to version 2008. And it still doesn't work.
Any help will be good;P
