Short answer: pplication). Example (Using Paging in SQL): string query = "SELECT * FROM Customers ORDER BY CustomerID OFFSET @Offset ROWS FETCH NEXT @PageSize ROWS ONLY"; SqlCommand command = new SqlCommand(query, connection); command.Parameters.AddWithValue("@Offset", pageNumber * pageSize); command.Parameters.AddWithValue("@PageSize", pageSize);… connection.Open();……… SqlDataReader reader = command.ExecuteReader(); while…

Explain a bit more

(reader.Read()) { // Process data } reader.Close(); connection.Close(); pplication).

Real-world example (ShopNest)

ShopNest’s reporting job still uses ADO.NET for a heavy SQL query where raw performance and stored procedures matter more than EF convenience.

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
