How can I effectively use async and await in C#?

How can I effectively use async and await in C#?

To effectively use async and await in C#, ensure your methods are marked as async and return a Task or Task<T>. This allows for non-blocking calls.

Can you explain the difference between Task and ValueTask?

Sure! Task is a reference type and is more commonly used, while ValueTask is a value type that can be more efficient in certain scenarios, especially when the result is already available.

What are some common pitfalls when using async in C#?

Common pitfalls include forgetting to await a task, which can lead to unexpected behavior, and using async void methods, which can make error handling difficult.

How do I handle exceptions in async methods?

You can handle exceptions in async methods using try-catch blocks. Just wrap your await calls in a try block to catch any exceptions that may occur.

Can you give an example of using async with a database call?

Certainly! You can use async with Entity Framework like this: await dbContext.SaveChangesAsync(); to save changes without blocking the thread.
