Virtuoso Entity Framework School DB Windows Form Application. This section demonstrates how Visual Studio 2008 can be used to generate mapping files for an Entity Data Model (EDM), based on a 1:1 mapping to tables in the School database. This will be done by creating a Windows Forms application in Visual Studio, create queries that access data in the School model, bind the query results to display controls to show the results of the queries, and then make updates to objects and persist the changes to the database.
