What is the difference between async and threading in C#?

What is the difference between async and threading in C#?

In C#, 'async' is used for asynchronous programming, allowing methods to run without blocking the main thread. Threading, on the other hand, involves creating new threads for concurrent execution.

Can you give me an example of when to use async instead of threading?

Sure! Use 'async' for I/O-bound operations like web requests, where waiting for a response is common. Threading is better for CPU-bound tasks that require heavy computation.

What are the performance implications of using async vs threading?

Async can be more efficient for I/O-bound tasks since it doesn't require additional threads, reducing overhead. Threading can be more performant for CPU-bound tasks but may lead to context switching overhead.

Are there any scenarios where threading is preferred over async?

Yes, for tasks that require parallel processing of data or heavy computations, threading is often preferred as it can utilize multiple CPU cores effectively.
