ASP.NET - Routing maps

Routing maps incoming URLs to controllers, actions, or endpoints. It determines how HTTP requests are processed by the application.

ASP.NET supports conventional routing, where URL patterns follow predefined rules, and attribute routing, where routes are defined directly on controllers or actions.

Routing improves readability and SEO by allowing clean, meaningful URLs instead of file-based paths. Example: /products/details/5.

In ASP.NET Core, routing is middleware-based and highly customizable. Developers can define route constraints and defaults.

Correct routing design is critical. Poor routing leads to broken links, security issues, and maintenance problems.
