为什么在ASP.NET CORE MVC中应用了错误的路由？

Question

I am working on ASP.NET CORE MVC project. Which has 2 routes:

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

    routes.MapRoute(
       name: "news",
       template: "News{controller}/{action}");
});

---

I noticed that in CORE 2.0 Framework the concept of defining specific routes at first do not apply for my 2 routes shown above. Is there a Bug? or there something wrong with my code?

---

When the URL - '/NewsHome/Index' is fetched it is calling the Home Controller Action method.

It should actually call the NewsHome Controller's Index method . What is wrong ?

I am also giving an extract from the book - 'Pro ASP.NET Core MVC 2 by Adam Freeman' to make my point. Please see below:

what is wrong, please guide me?

Answer 1

The answer is in the screenshot you posted. You should reverse the order of the mappings. In the screenshot it's showing how it would be wrong.

Answer 2

It's behaving exactly as explained in the book. Just invert the order of your routes.

Answer 3

change

routes.MapRoute(
   name: "news",
   template: "News{controller}/{action}");

TO

routes.MapRoute(
   name: "news",
   template: "/news/{action}");
