Is there any proof that async await is actually better than . . . Libraries now need to offer both sync and async variants of any component which could depend on either a sync or async component Every method adorned with async requires a heap allocation for Task, and the alternative ValueTask has significant caveats
Async Await - Best Practices in Asynchronous Programming Async void methods have different composing semantics Async methods returning Task or Task<T> can be easily composed using await, Task WhenAny, Task WhenAll and so on Async methods returning void don’t provide an easy way to notify the calling code that they’ve completed
How to separate sync and async methods in C# type? Should I add async methods to the same file in a #region Async? Never #region is a bandaid You're better off taking the time and refactoring things well, or splitting them off into components
Should I expose asynchronous wrappers for synchronous methods? The choice of whether to invoke the synchronous method asynchronously is left up to the developer Async wrappers around sync methods have overhead (e g allocating the object to represent the operation, context switches, synchronization around queues, etc )
C#: Async vs Sync | Differences between Asynchronous and . . . The main difference between async and sync programming in C# is that async allows for non-blocking code execution, while, sync blocks the calling thread until the called method returns With async, the thread continues to execute other code while the called method is running
