I’ve been programming async C# for years, but today was the first time I noticed a method that returns a Task without using the async and await keywords.

What is the difference between these 2 methods?

Task<int> SomeMethod()
{
  return SomeAsyncMethod();
}

versus

async Task<int> SomeMethod()
{
  return await SomeAsyncMethod();
}

In what situation should/shouldn’t we use the async and await keywords?

Is there a performance difference?

There is probably already an answer to this question, but I can not find it.
