非异步异步方法的命名约定是什么？

Question

As is known to all, in C#, async methods are supposed to be named with suffix "Async" (eg ReadAsync , CreateAsync ).

But in many cases, async/await is not necessary in an asynchronous method, for instance:

public async Task<string> DoSomethingAsync()
{
    return await GetAsync();
}

can be rewritten as:

public Task<string> DoSomethingAsync()
{
    return GetAsync();
}

My question is:

1. For the situation above where async/await is totally optional, which version is the more correct? Keep the async/await or return a Task directly?

2. If the second version is better (returning a Task directly), should it conventionally still be named with suffix "Async" (ie DoSomethingAsync ) or not (ie DoSomething )?

I prefer returning a Task directly, but I've written an entire blog post on when this is appropriate and not .

Yes. The Async suffix means "returns an awaitable".
