Relaxation APIs need to use attribute routing to product the app's performance as being a list of means wherever operations are represented by HTTP verbs.
We may also constrain the routes by specifying the Typical Expression for controller, action strategy and many others.
The worth of controller and motion are Portion of both of those ambient values and values. The method Url.Motion often takes advantage of the current values of action and controller and generates a URL route that routes to The existing motion.
..By defining a different Route that tells the routing handler the way to navigate to an action method, any time a ‘group’ parameter is specified to the Index process. The route is follows
