Define an ADO.NET entity data model for the customer table

To have a strongly-typed model for accessing the data, you can add an Entity Model to your project in Visual Studio in the following way:

1. Create a folder, named Model, under the root of your project.
2. Open the context menu of the folder and click Add » New Item...
3. In the left pane, under Visual C#, click Data.
4. In the center pane, click ADO.NET Entity Data Model.
5. In Name input field, enter MembershipModel.edmx and click Add.
   The Entity Data Model Wizard window appears.
6. Select the EF Designer from database model and click Next.
7. Connect to the database you created.
8.   Add the Customers table from the database to the model and click Finish.

The data model is created and a CustomMembershipProviderEntities class is created, which is used later on in the sample code.
