To improve the performance of ADO.NET applications, you can follow these steps: 1) Use parameters instead of string concatenation to prevent SQL injection attacks and improve query performance. 2) Use CommandBehavior.SequentialAccess when dealing with large amounts of data to read data in chunks instead of all at once. 3) Use typed datasets or DataTables instead of untyped datasets for better performance and type safety. 4) Avoid unnecessary round trips to the database by using caching strategies like Query Notification and DataSet Caching. 5) Optimize SQL queries by using indexes, joining tables efficiently, and reducing the number of subqueries.
