SaveChanges Correctly in EF Core

Summary

The transcript discusses an inefficient approach to database operations when looping through a list and saving items individually, which creates multiple transactions and degrades performance. The key recommendation is to batch database inserts by adding all items first and then saving them collectively, allowing Entity Framework to optimize transaction handling. By using bulk save methods instead of per-row saves, developers can significantly reduce database round trips and minimize lock contention. This technique provides a simple performance optimization strategy for .NET database interactions.
