- References to the System, System.Data, System.Windows.Forms, and System.XML assemblies.
For information about building this example from the command line for [!INCLUDEvbprvb] or [!INCLUDEcsprcs], see Building from the Command Line or Command-line Building With csc.exe.

.NET Framework Security
Storing sensitive information, such as a password, within the connection string can affect the security of your application. Using Windows Authentication (also known as integrated security) is a more secure way to control access to a database. For more information, see Protecting Connection Information.
