Entity Framework Core 7 RC2 has been released with all the features planned for the GA release, including mapping to SQL Server JSON Columns, ExecuteUpdate and ExecuteDelete (Bulk updates), improved performance for SaveChanges, table-per-concrete-type (TPC) inheritance mapping, customizable model building conventions, stored procedure mapping for inserts, updates, and deletes, new and improved interceptors and events, and query enhancements. The blog post takes a deep dive into mapping .NET aggregates to JSON documents and using them in relational databases. The provider-agnostic support for JSON columns is available in EF7 with an implementation for SQL Server. SQLite support for JSON is planned for post EF7, and the PostgreSQL and Pomelo MySQL providers already contain some support for JSON columns.
