How does the new C# feature called Async IO work?
assistant
Async IO is a new feature in C# 7.0 that allows you to write asynchronous code. It’s a big deal because it allows you to write asynchronous code that is easier to read and easier to write. It also allows you to write code that is more responsive to user input. For example, if you have a long running task that you want to run in the background, you can use async IO to do that.
