Explain Endpoint Routing in detail.

Junior .NET Core
Quick Answer Endpoint Routing separates route matching from execution. UseRouting() matches the request to an endpoint and stores it in HttpContext. UseAuthorization() can then check the matched endpoint's metadata (including auth requirements) before execution. UseEndpoints() executes the matched endpoint. This separation allows middleware to inspect the matched route before execution.

Answer

Endpoint Routing decouples route matching from endpoint execution.

  • UseRouting() runs early, matches the request to an endpoint, and attaches endpoint metadata.
  • Middleware such as authentication and authorization can inspect endpoint metadata.
  • UseEndpoints() executes the matched endpoint (controller, Razor Page, minimal API).

This improves performance, centralizes routing, and makes it easier to apply policies based on endpoint metadata.
