    EF Core Data Correctness and Safe Schema Delivery

    A practical .NET 10 and EF Core 10 course for developers who know C# and basic database access. Follow one evolving order-management scenario through safe tracked updates, optimistic concurrency, retry-safe transactions, reviewed migrations, resumable backfills and deployment recovery. Six substantial lessons include worked examples, exercises with solutions, and a separate 10-question scenario assessment for every lesson. All lessons and tests are included in TechInterviewNotes Full Access. SQL Server-specific behavior is identified explicitly.
