Weekly Recap

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.
