Speed and allocations matter — especially when you’re writing performance-critical C# code. But not all heap allocations are obvious. Some come from interface calls, lambdas, value type boxing, and other seemingly innocent code. In this video, we’ll use BenchmarkDotNet to measure and expose hidden memory costs in real C# code. No Unity, no guesswork — just precise numbers, explained clearly. If you’ve ever wondered where your allocations are really coming from, this is for you.
