![Weekly Recap: Entity Framework Core, the Memento Pattern, and C# Design Patterns [Jun 2026]](https://devleader-d2f9ggbjfpdqcka7.z01.azurefd.net/media/SquareBanner.webp)
This week: A heavy dose of Entity Framework Core -- the complete guide, getting started in ASP.NET Core, CRUD operations, and managing your schema with migrations. On the design pattern side there's a full run on the Memento pattern (implementation, best practices, when to use it, and Memento vs State), plus Interpreter and Mediator pattern guides and a look at SOLID violations and the Dependency Inversion Principle. The videos lean into engineering leadership: prioritizing tech debt, build vs buy vs adopt, agent orchestration, and what it takes to earn a senior promotion.
Like what you read or watched from the recap? I'd love if you helped share on Reddit or Daily.dev so others can see!
