Asynchronous Methods

Question

I am trying to convert my methods to asynchronous.
I have added async Task<IActionResult> and seems the methods work fine.
However, just it is enough to make them asynchronous? Wouldn't I need an "await" somewhere? but where ?

// CONTROLLER
public async Task<IActionResult> GetProducts()
{
try
{
return Ok(_productServices.GetAllProducts());
}
catch (Exception ex)
{
return StatusCode(500, "");
}
}

// SERVICES
public IEnumerable<ProductModel> GetAllProducts()
{
var products = List<ProductModel>() {
...
}
return products
}

Thank you,

Yes you need an await somewhere. More important to that is it helps to understand that neither await nor async creates tasks, they support multitasking. You need to do something (else) that creates a task.

Many developers prefer await and async but in my opinion they are unnecessarily complicated. You can do multitasking without them.

If GetProducts don't call await, It‘s unnecessary to claim async.
Only Task and async functions need to await. async and await.
