You need to modify Web.config to map requests for your HTML files to TransferRequestHandler.

like so:

<system.webServer>
    ...
    <handlers>
      <add name="HtmlFileHandler" path="*.html" verb="GET" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
    </handlers>
    ...
  </system.webServer>

This is explained here by Jon Galloway.

And put this to your RouteConfig:

public static void RegisterRoutes(RouteCollection routes)
        {
            ...
            routes.MapRoute("Default", "{controller}/{action}.html", new { controller = "Home", action = "Index" });
            ...
        }

Than accessing http://localhost:{port}/Home/Index.html will send you to your Home page.
