Of the four circumstances case one: is exciting for the reason that as we see, we can combine thoroughly clean urls with urls applying named query strings. This is due to the sequence of parameters is significant. So we can't blend up the sequence of parameters in URL and anticipate MVC to know it.

Including routes working with MapControllerRoute, MapDefaultControllerRoute, and MapAreaControllerRoute immediately assign an buy benefit for their endpoints according to the buy They are really invoked. Matches from a route that appears earlier have a better precedence. Common routing is order-dependent.

This mapping is finished by the routing principles outlined in your software. For instance, if we concern a ask for to your “/Dwelling/Index” URL, then it's the Index motion method of the house Controller course that is going to deal with the request as shown within the beneath picture.
