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

Async and await are used in C# to simplify asynchronous programming. For example, you can use them to perform I/O operations without blocking the main thread.

Can you show me a simple code example?

Sure! Here's a basic example:

public async Task<string> GetDataAsync()
{
    using (HttpClient client = new HttpClient())
    {
        var response = await client.GetStringAsync("https://api.example.com/data");
        return response;
    }
}

What happens if I don't use await?

If you don't use await, the method will return a Task immediately, and the code following 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 as short as possible.
