How and when to use ‘async’ and ‘await’

Question

From my understanding one of the main things that async and await do is to make code easy to write and read - but is using them equal to spawning background threads to perfo

Answer 1

The way I understand it is also, there should be a third term added to the mix: Task.

Async is just a qualifier you put on your method to say it's an asynchronous method.

Task is the return of the async function. It executes asynchronously.

You await a Task. When code execution reaches this line, control jumps out back to caller of your surrounding original function.

If instead, you assign the return of an async function (ie Task) to a variable, when code execution reaches this line, it just continues past that line in the surrounding function while the Task executes asynchronously.
