What are some examples of using async and await in C#?

Can you explain how async and await work in C#?

Sure! In C#, async and await are used to write asynchronous code. The async keyword is applied to a method, indicating that it contains asynchronous operations, while await is used to pause the execution of the method until the awaited task completes.

Can you provide a simple example of using async and await?

Absolutely! Here's a simple example:

public async Task<string> GetDataAsync() {
    await Task.Delay(2000); // Simulates a delay
    return "Data retrieved!";
}

In this example, GetDataAsync simulates a delay of 2 seconds before returning a string.

What happens if I don't use await with an async method?

If you don't use await, the method will start executing asynchronously, but the calling method won't wait for it to complete. This can lead to unexpected behavior, as the calling method may continue executing before the async method finishes.

Are there any best practices for using async and await?

Yes! Some best practices include:

1. Always use await with async methods to avoid unhandled exceptions.
2. Avoid blocking calls like .Result or .Wait() on async methods.
3. Keep async methods short and focused.
