I'm a MCT and currently in the process of preparing the Course 6464A: Visual Studio® 2008: ADO.NET 3.5.
In that course the studets need the ContosoMedicalDb sample database. As in our training facility we do not use the official images that Microsoft provides, I was myself in search for this database. Finally I found it somewhere on the net, but only in a SQL Server 2005 backup format. As I use SQL Server 2008 it took some time until I had it ready to use.
To spare you the trouble of having to do the same, I provide here a SQL script for the ContosoMedicalDb that will create the database (including the data). The script however assumes that you have already created a database with the name ContosoMedicalDB yourself.
Hope this saves someone some time.
