Hands-On RESTful Web Services with ASP.NET Core 3

Custom attribute routing

The routing engine of ASP.NET Core also provides a way for us to create our routing attributes. This technique is useful in complex routing systems where it is essential to keep a conceptual order between different routes. An example of a custom routing definition is as follows:

using System;using Microsoft.AspNetCore.Mvc.Routing;namespace SampleAPI.CustomRouting{    public class CustomOrdersRoute : Attribute, IRouteTemplateProvider    {        public string Template => "api/orders";        public int? Order { get; set; }        public string Name => "Orders_route";    }}
