Explore the inner workings of Entity Framework Core (EF Core) to optimize database access in C# applications. Gain insights into querying techniques, relationship handling, unit testing strategies, and Domain-Driven Design implementation. Discover the changes introduced in EF Core 3, including Cosmos DB integration. Learn how to write more efficient database access code by understanding EF Core's internal processes, from basic database operations to advanced concepts like relational fixup and soft delete. Dive into practical examples, including a super-simple database demonstration, various querying methods, and the SQL generated by EF Core. Enhance your skills in configuring EF Core through code and leverage ValueConversions for improved data handling.
