.NET Tasks, List's ForEach, and Problems

This technical article analyzes a common pitfall in C# when using the List.ForEach method with asynchronous lambda expressions, which leads to unexpected behavior because the delegate returns void. It recreates the problematic code, explains why the async operations are not awaited, and offers two solutions: using a standard foreach loop or implementing a custom ForEachAsync extension method to properly await tasks.
