Entity Framework Core best practices guide covering design, performance, security, and testing patterns.

• Covers eight core areas: DbContext design, entity modeling, performance optimization, migrations, querying strategies, change tracking, security, and testing approaches
• Emphasizes practical patterns like DbContextFactory, IEntityTypeConfiguration separation, AsNoTracking() for read-only queries, and compiled queries for frequently executed operations
• Includes migration best practices such as descriptive naming, SQL verification before production, and data seeding through migrations
• Addresses common pitfalls: N+1 query problems, SQL injection prevention, appropriate DbContext lifetimes, and concurrency control for multi-user scenarios
• Recommends testing strategies using in-memory providers for unit tests and SQLite for integration tests
