What do you get in this .NET newsletter?
This isn't a link dump. Every issue has original content you won't find on the blog or anywhere else.
Real Benchmarks, Not Theory
I benchmark things in actual .NET projects so you don't have to. EF Core vs Dapper? Minimal API vs Controllers? Get numbers, not opinions.
"Use X, Not Y" Verdicts
Every week I pick a common .NET decision and give you a straight answer. No "it depends" — just a clear recommendation with reasoning.
5-Minute Production Tips
Quick wins you can ship today. Middleware tricks, EF Core gotchas, Docker optimizations — the stuff you only learn from building real apps.
Weekly Interview Question
A senior-level .NET question with a detailed answer. Great for interview prep — or just to test how well you really know the framework.
