What are the best practices for using async and await in C#?

What are the best practices for using async and await in C#?

Some best practices include using async all the way down, avoiding blocking calls, and handling exceptions properly.

Can you explain why I should avoid blocking calls?

Blocking calls can lead to thread pool exhaustion and degrade performance, especially in high-load applications.

What about exception handling in async methods?

You should use try-catch blocks within async methods to handle exceptions, as they won't propagate like in synchronous code.

Are there any specific scenarios where I shouldn't use async/await?

Yes, for CPU-bound operations, consider using Task.Run instead of async/await to avoid blocking the main thread.
