ASP.NET Controller: An asynchronous module or handler completed while an asynchronous operation was still pending

Question

I have a very simple ASP.NET MVC 4 controller:

public class HomeController : Controller
{
    private const string MY_URL = \"http://smthing\";
    private r

I ran into related issue. A client is using an Interface that returns Task and is implemented with async.

In Visual Studio 2015, the client method which is async and which does not use the await keyword when invoking the method receives no warning or error, the code compiles cleanly. A race condition is promoted to production.
