25 Async Await, Async File IO, HttpClient

In this hands-on session, we explore modern *Asynchronous Programming in .NET* using `async` and `await`. You’ll understand why synchronous I/O blocks threads and how asynchronous I/O improves scalability and responsiveness in web and UI applications.

We walk through practical examples including async File I/O, working with `FileStream`, and making HTTP requests using `HttpClient`, along with JSON deserialization.
