The Route labeled (1) is named ‘Default’ and it's a url template of variety controller / action / id . Notice the third parameter, which can be an anonymous object with a few Attributes, each of which matches a piece in the url template.
This is the code from the application get started function in Worldwide.asax from the MVC App which we designed within the former chapter.
This portion displays a primary example of customizing routing applying software product. The subsequent code tends to make routes about line up Along with the folder framework of the challenge.
Anything following the “” could be regarded as the controller identify. In the same way, anything at all after the controller name will be considered as the action name and the value in the id parameter.

This sort of routing is utilized to simply accept any amount of url arguments and popularly often called CatchAll circumstance exactly where any details soon after particular segments are caught.
I uploaded the resource code to GitHub if you wish to down load it and Participate in a tiny bit all over with unique routes.
