Question

Given the following ASP.NET MVC 4 controller action:

public async Task<ActionResult> FooAsync()
{
    using (var httpClient = new HttpClient())
    {
        var responseMessage = await httpClient.GetAsync("http://stackoverflow.com");
        string response = await responseMessage.Content.ReadAsStringAsync();

        return Content(response);
    }
}

Do I need to put the “Async” suffix in FooAsync for the action to be run asynchronously?

Answer 1

No, this is not a requirement.

By convention, you append “Async” to the names of methods that have
an Async or async modifier.

You can ignore the convention where an event, base class, or interface
contract suggests a different name. For example, you shouldn’t rename
common event handlers, such as Button1_Click.
