How do I use async and await in C#?

Using async and await in C# allows you to write asynchronous code more easily. You can mark a method with the 'async' keyword and use 'await' to call asynchronous methods.

Can you give me an example of an async method?

Sure! Here's a simple example:

public async Task<string> GetDataAsync()
{
    await Task.Delay(1000); // Simulates a delay
    return "Data retrieved!";
}

What happens if I don't use await?

If you don't use await, the method will return immediately, and the code after the asynchronous call will execute without waiting for the task to complete.

Are there any best practices for using async and await?

Yes, some best practices include avoiding blocking calls, using ConfigureAwait(false) in library code, and keeping async methods short and focused.
