Excerpt

Optimizing EF Core Queries

Diagnose and fix slow Entity Framework Core (EF Core) queries. Start from the generated SQL/logs, apply the smallest change that removes the bottleneck, and confirm the fix by re-reading the SQL and the query count. Prefer changes that reduce round-trips, duplicated rows, scans, or per-call translation cost over micro-optimizations. Apply one change at a time and re-measure.
