How to disable change tracking globally?

Short answer: You can disable tracking by default for a specific DbContext using: optionsBuilder.UseQueryTrackingBehavior(QueryTrackingBehavior.NoTrac king); Or per-query using .AsNoTracking().

Real-world example (ShopNest)

Read-only catalog pages use AsNoTracking() so EF Core does not spend time snapshotting entities you will never update.

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.
