Why Async/Await Don't Work With Array Methods in .NET
Because of its many advantages in terms of scalability and responsiveness, asynchronous programming in.NET has become a standard feature in modern application development. However, attempting to utilize async/await with array methods like ForEach, Select, or Map (in contexts inspired by JavaScript) is one of the main mistakes that developers face. In addition to offering workable options for managing asynchronous actions with collections in.NET, this article investigates why this method doesn't function as intended. Understanding the Problem Array Methods and Delegates Array methods in .NET, such as ForEach or LINQ’s Select, are designed to execute synchronously. For example: These methods allow you to pass a delegate (like a lambda function) that is either executed sequentially or in a manner that follows the method's design. The compiler allows the usage of an async lambda but gives a warning if you try to do so: LINQ and Deferred Execution LINQ methods like Select and Where...
