![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 digs into Entity Framework Core from setup through CRUD operations and schema migrations, plus a deep run on the Memento pattern and other C# design patterns like Interpreter and Mediator. New videos cover tackling tech debt, build vs buy decisions, and growing into senior and leadership roles.
This week is a full walkthrough of the SOLID principles in C# -- single responsibility, open/closed, Liskov substitution, and interface segregation -- plus design pattern guides for the mediator, iterator, and memento patterns. There's also practical ASP.NET Core Web API coverage on deploying to Azure and Docker and writing integration tests, with new videos on engineering management, plugin architecture, and tech debt.
This week digs into building ASP.NET Core Web APIs: controllers, minimal APIs, model validation, error handling, versioning, and JWT auth. Plus a full run through the iterator, mediator, and chain of responsibility patterns in C#, with new videos on engineering careers, testing, and single points of failure.
This week covers the chain of responsibility design pattern in C# end-to-end with the complete guide, implementation, decision guide, and best practices, plus the template method pattern with a real-world example, best practices, and a strategy pattern comparison. On the reflection side, we have expression trees as a reflection alternative, UnsafeAccessor for private member access, Native AOT safety with DynamicallyAccessedMembers, reflection vs source generators, and how DI containers use reflection internally. Rounding it out: the complete ASP.NET Core Web API guide and a deep look at ASP.NET Core routing.
This week dives deep into C# reflection in .NET 10 with the complete guide, anti-patterns, performance benchmarks, custom attributes, PropertyInfo and MethodInfo, FrozenDictionary caching, and the Activator.CreateInstance vs compiled expressions trade-off. Plus complete coverage of the template method pattern, the proxy pattern with a real-world example, best practices, and a decorator comparison, a flyweight real-world example, and a tour of the new LINQ methods in .NET 6 through 10.
This week takes a deep tour of LINQ in C# covering grouping, aggregation, set operations, joins, deferred execution, and element access, plus complete guides to the proxy, flyweight, and bridge design patterns. The video lineup tackles context switching, generational dynamics on engineering teams, and where AI tooling actually fits in a real developer workflow.
This week brings deep coverage of LINQ in C# (filtering, projection, ordering, and the complete guide), advanced regex topics including named capture groups and pattern syntax, plus practical guides on the bridge, facade, and flyweight design patterns. Plus four new videos covering platform team work, agentic systems, and developer mindset.
This week delivers complete coverage of C# enums -- flags, switch patterns, and string conversion -- plus the facade and bridge design patterns in C#. Videos cover manager effectiveness and building for reusability.
This week covers complete guides on C# regular expressions, state pattern best practices, and command pattern real-world implementations. Plus feature slicing vs clean architecture, CQRS per feature, and C# string performance deep dives.
This week covers complete guides on command, state, adapter, and composite design patterns in C#, plus deep dives into string manipulation and feature slicing in .NET. New videos discuss AI tool costs, burnout, and managing context switching.
This week covers building extensible plugin systems in C#, the adapter design pattern in depth, and practical C# source generator testing. Plus new videos on developer burnout, staying sharp after promotion, and whether Copilot CLI is finally replacing Visual Studio.
This week covers building AI developer tools with the GitHub Copilot SDK in C# -- from CLI tools and coding agents to ASP.NET Core AI APIs -- plus deep dives into C# source generators with incremental pipelines and Roslyn syntax trees, and practical guides on observer, singleton, decorator, and factory method design patterns.
This week covers C# design patterns with deep dives into Singleton and Decorator patterns, plus source generator internals and getting started with the GitHub Copilot SDK in C#. Videos tackle developer career topics including tech debt, overcommunicating, and the ROI of learning C#.
Build multi-agent orchestration with Semantic Kernel in C#, including ChatCompletionAgent, vector stores, and plugin patterns. Plus C# design patterns including Singleton, Decorator, Strategy, and Prototype!
This week covers building AI-powered applications with Semantic Kernel and the GitHub Copilot SDK in C#, from custom plugins and RAG to multi-agent patterns. Plus a deep dive into C# design patterns -- Strategy, Prototype, and Factory Method complete guides.
This week covers the Microsoft Agent Framework in C# -- from core AIAgent abstractions to AgentSessions and function tools -- plus Semantic Kernel agents and plugins, Builder pattern deep dives, and GitHub Copilot SDK development. Also included: new videos on software engineering planning and hiring insights.
