A practical guide to spotting N+1 queries in EF Core 11: what the pattern looks like in real code, how to surface it via logging, diagnostic interceptors, OpenTelemetry, and a test that fails the build when a hot path regresses.

A practical guide to EF Core 11 compiled queries: when EF.CompileAsyncQuery actually wins, the static-field pattern, the Include and tracking gotchas, and how to benchmark before and after so you can prove it was worth the extra ceremony.

Strip Android and iOS from a .NET MAUI 11 project so it ships Windows and Mac Catalyst only: the csproj edits, the workload commands, and the multi-targeting that keeps your code clean.

A practical guide to mixing C# records and EF Core 11. Where records fit, where they break change tracking, and how to model value objects, entities, and projections without fighting the framework.

Seven ways to return more than one value from a C# 14 method: named tuples, out parameters, records, structs, deconstruction, and the extension-member trick for types you don't own. Real benchmarks and a decision matrix at the end.
