What is the purpose of async and await in Xamarin.Forms?

Async and await are used in Xamarin.Forms to simplify asynchronous programming, allowing for non-blocking UI updates.

Can you give me an example of how to use async and await in a Xamarin.Forms application?

Sure! You can define an async method like this: async Task LoadDataAsync() { var data = await GetDataAsync(); }.

What happens if I don't use async and await?

If you don't use them, your UI may freeze while waiting for tasks to complete, leading to a poor user experience.

Are there any best practices for using async and await?

Yes, always use async methods for I/O-bound operations, avoid blocking calls, and handle exceptions properly.
