- EF Core 11 translates Contains to JSON_CONTAINS on SQL Server 2025
EF Core 11 auto-translates LINQ Contains over JSON collections to the new SQL Server 2025 JSON_CONTAINS function, and adds EF.Functions.JsonContains for path-scoped and mode-specific queries that can hit a JSON index.
- EF Core 11 Adds GetEntriesForState to Skip DetectChanges
EF Core 11 Preview 3 introduces ChangeTracker.GetEntriesForState, a state-filtered enumerator that avoids an extra DetectChanges pass in hot paths like SaveChanges interceptors and audit hooks.
- EF Core 11 turns on Cosmos DB transactional batches by default
EF Core 11 groups Cosmos DB writes into transactional batches per container and partition on every SaveChanges, giving best-effort atomicity and fewer roundtrips without any code changes.
