The goal of this chapter is to show how you can take advantage of the new features in .NET Framework 4.0 with Windows Forms. In this section you learn how to create an application that queries and manipulates master-detail data from the Northwind database via the ADO.NET Entity Framework, also showing data results as a chart. When you create a new Win Form project, add a new Entity Data Model to the project pointing to the Northwind database as you learned in Chapter 27, “Introducing the ADO.NET Entity Framework.” The EDM needs to get the
Order_Details tables. Ensure that your result looks like Figure 30.3.
