Should I use await with async Action method?

Question

I need to implement an asynch Action in my Controller for a long running external API call.

Looking at some tutorials, I have implemented my method like this:

As the other person wrote you need an asynchronous action to await it, to make View() async wrap it in a Task.Run

[AsyncTimeout(200)]
public async Task DoAsync()
{
    // Execute long running call.
    return await Task.Run(() => View());
}

Afterwards this method is mainly useful for calling from other async functions or callbacks.
