Why does Index() fire twice?

Question

ASP.NET

I have VS 2015 Community UP1, ASP.NET5 MVC6. When creating a new project, the HomeController class is created by default, where there is

public IActionResult Index()
 {
       return View();
 }

If we put a breakpoint on return View(), then we will fly there twice, WHY?

Answer 1

Well, you can have whatever you want in any configuration, as a rule, this does not play a special role. Let's clarify the sequence of actions - you deploy the application, turn on debugging, open the default page and you hit the breakpoint twice? Or do you take some other steps that you decided not to mention?
