![Weekly Recap: C# Reflection in .NET 10, Template Method, and Proxy Patterns [May 2026]](https://devleader-d2f9ggbjfpdqcka7.z01.azurefd.net/media/SquareBanner.webp)
This week: Seven articles take a deep look at C# reflection in .NET 10 -- the complete guide, anti-patterns, performance benchmarks, custom attributes, PropertyInfo and MethodInfo, FrozenDictionary caching, and the Activator.CreateInstance vs compiled expressions trade-off. Three template method pattern articles and four proxy pattern articles round out the design pattern coverage, alongside a flyweight real-world example and a tour of the newer LINQ methods in .NET 6 through 10. Six new videos cover handling tough manager situations, code coverage gates, useless certifications, recognizing great developers, building agentic AI workflows, and why I stopped giving my opinions at work.
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!
