Routing/Resolving asp.net mvc

Question

I have a question that I have been thinking about.

What happens from when I enter an URL in my browser and click enter to when the code in the corresponding controller actually executes?

Let's say I have an asp.net mvc application and a trivial Controller like this:

public class HomeController : Controller
{
  public ActionResult About(int id = 25)
  {
    //code
  }
}

So if I enter like myUrl/home/about?id=56 that controller gets invoked. I know there is a routing pattern like {controller}/{action}/{id} declared by default. But if an URL matches that pattern is a controller instance created then or what happens? Is there some Resolver class or similar? Is there like a List containing all the controllers so "Home" in the URL matches the HomeController?

I know the id parameter in the controller signature will be bound to the corresponding id value in the request context with the help of model binding. But there must be a lot of other magic happening here.

Hope someone can help a fresh confused asp.net mvc user

in a nutshell:

DefaultControllerFactory finds and instantiates the controller by its name using reflection (more info)
ControllerActionInvoker finds and invokes the action by its name using reflection (more info)

Good overall description can be found here.
