Entity Framework Core data access, query behavior, and production pitfalls.
Practice items tagged with EF Core.
Explains how tenant query filters help, where they can be bypassed, and what extra safeguards protect tenant isolation.
Explains audit fields and data change tracking with practical .NET data-access examples and production trade-offs.
Loads a resource once, evaluates owner-or-capability authorization, and avoids trusting route ownership claims.
Explains dynamic filters and SQL injection risk with practical .NET data-access examples and production trade-offs.
Implements bounded filtering and deterministic keyset pagination without accepting arbitrary query expressions.
Creates a resource through an explicit request DTO and returns typed 201, 409, and validation outcomes.
