Restore NuGet packages
Visual Studio C# projects included with the Ventura SQL templates have their NuGet packages folder deleted. This was done to keep the Ventura SQL installer small.
The Visual Studio solution needs to restore the NuGet packages folder. See topic Restore NuGet packages for more information.
In Visual Studio go to Build -> Rebuild Solution and wait for the packages to be restored.
Right-click "References" in the Solution Explorer and select "Manage NuGet Packages".
Select the "Installed" tab.
The package "System.Data.SqlClient" is the ADO.NET Provider for SQL Server (including Azure SQL).

The MainWindow is the starting point for the application.
Depending on the radio-button selected in the main window dialog, the VenturaConfig.DefaultConnector property is set to an AdoConnector or HttpConnector.
The AdoConnector connects to the Azure SQL demo database.
The HttpConnector connects with the the middle-tier. We will walk through the middle-tier project in the next topic.
The Recordset.ExecSql() and Recordset.SaveChanges() methods will use the VenturaConfig.DefaultConnector if no connector is specified as a parameter.
The code-behind for the CustomerList window.
1) The CustomersListRecordset _rs is declared.
