Real benchmark results comparing IAsyncEnumerable and Task.WhenAll. Learn when to choose speed vs responsiveness, memory efficiency, and user experience in C# async operations.
Why I Avoid Static Helpers in Modern C# Projects
Most projects I review have a Utils or Helpers class packed with static methods. At first glance, static helpers look like the fastest way to solve problems. You don’t need to new up objects or wire dependencies. Just call Helper.DoSomething() and move on. That convenience is exactly why they sneak into codebases. But over time, static helpers turn into a source of pain, especially in production systems that need to evolve. ...
