Entity classes can be used as object
data sources, and as such can be added to the Data Sources window and placed on forms like any other
Windows Forms controls. By placing an entity-based data source on a Windows form, you can create
databound controls.
On the first page of the wizard, choose a data source type (specify where your data for the data source
will come from). By default, Database is selected, but what you want to select is Object because the
data will be coming from an entity object. So, select Object and click Next.
The next page asks you to select the object that you would like to bind to. Listed on this page are those
objects in the current assembly. Your project is listed, and you need to expand that node to get to the
information you want. Expand the LINQ node and select the Contact object (see Figure 15-18).
Notice that all of the objects here are objects within your project plus entities you have defined in the
O/R Designer.
