You add [MemoryDiagnoser] and [Benchmark] to a class, run dotnet run -c Release , and BenchmarkDotNet hands you back a beautifully formatted table: mean, median, standard deviation, allocated bytes per operation. It's one of the best measurement tools in any ecosystem. And then what? You read the numbers. You compare them, in your head, to what you remember from last week. Maybe you screenshot the table and paste it into a Slack message. Maybe you don't, because nothing regressed...
