10:55 Mapping to JSON columns using SQLite
13:53 Leverage the new support for performance improvements, e.g. when using Contains
16:42 Use C# structs with DDD value object semantics in your classes while still splitting the contents to multiple columns in the database
23:58 Raw SQL queries for unmapped types
27:53 Official `HierarchyId` support for EF Core on SQL Server
33:29 In Summary Improvements to lazy loading and the change tracking APIs
