Q. Why it is important to Connection close an ADO.NET in application?
A. Connections need to be closed properly because it affects the scalability and reliability of the applications.
For open connections it is always vulnerable to attack, so to be short, ‘Open connections as late as possible and close it as early as possible’. We can ‘Close’ the connections by ‘final’ block or ‘using’ the USING statement.
