Home Archive EF Core, C# 14, and clean code tradeoffs – .NET News Daily Issue #433 (Apr 14, 2026)

Editor's note

I pulled together another deliberately mixed issue today, with a nice balance of language features, architecture, and data access. The EF Core transactions article is practical and worth your time if you deal with consistency bugs, and the piece on calling ToList() before Where() is a useful reminder that small LINQ choices can turn into real performance costs. I also liked seeing both sides of the clean code discussion represented in the same lineup.
