See the interpreter pattern in action with a complete real-world C# example building a search query DSL with expression parsing and evaluation.

Welcome to another issue of Dev Leader Weekly! In this issue, I dig into a Reddit thread about engineers reporting directly to a product manager -- the healthy conflict you lose, the career and delivery risks, and how to make it work if you find yourself in that spot.

How to use IHttpClientFactory in .NET 10 the right way -- comparing basic factory, named clients, and typed clients with real C# examples, and explaining why typed clients can break in singletons.

How to implement the visitor pattern in C# with step-by-step code examples for double dispatch, element hierarchies, and algorithm separation.

This week goes deep on Entity Framework Core -- relationships, LINQ querying, performance tuning, testing strategies, and how it compares to Dapper -- plus HttpClient and IHttpClientFactory patterns in .NET. There's also a full run of C# design patterns covering Visitor, Interpreter, and Memento, alongside new videos on debugging, AI in your development workflow, and engineering leadership.

The definitive guide to HttpClient in C# and .NET 10 -- covering correct usage patterns, IHttpClientFactory, DNS pitfalls, resilience, streaming, HTTP/3, testing, and observability. No other article you'll need.
