The Route labeled (one) is named ‘Default’ and it's got a url template of style controller / action / id . Notice the third parameter, that's an anonymous item with three Homes, Each and every of which matches a bit inside the url template.

Defaults specify which controller, motion method, or worth of id parameter need to be made use of if they don't exist inside the incoming request URL.

Routing with Specific people can result in surprising final results. Such as, take into account a controller with the following motion technique:

Attribute routing works by using a set of attributes to map actions on to route templates. The following StartUp.Configure code is normal for just a Relaxation API and is Utilized in the next sample:

ASP.Web Core apps can blend the usage of traditional routing and attribute routing. It really is common to make use of conventional routes for controllers serving HTML pages for browsers, and attribute routing for controllers serving Relaxation APIs.

Attribute routing supports defining many routes that get to the identical action. The most typical utilization of this is to imitate the habits from the default common route as demonstrated in the subsequent case in point:
