As I am using .Net Core MVC something like this helped me:

    public class HomeController : Controller
    {
        public IActionResult Index()
        {
            var url = Request.Path + Request.QueryString;
            return App(url);
        }

        [Route("App")]
        public IActionResult App(string url)
        {
            return View("/wwwroot/app/build/index.html");
        }
   }

Basically in MVC side, all the routes not matching will fall into to Home/Index as it specified in startup.cs. Inside Index it is possible to get the original request url and pass it wherever needed.

startup.cs

        app.UseMvc(routes =>
        {
            routes.MapRoute(
                name: "default",
                template: "{controller=Home}/{action=Index}/{id?}");

            routes.MapSpaFallbackRoute(
                name: "spa-fallback",
                defaults: new { controller = "Home", action = "Index" });
        });
