Securing routes with [Authorize] and [AllowAnonymous]?

Short answer: [Authorize]: Requires authenticated user [Authorize(Roles = "Admin")]: Requires role [AllowAnonymous]: Allows access without login

Example code

[Authorize] public IActionResult Dashboard() { } [AllowAnonymous] public IActionResult Login() { }

Real-world example (ShopNest)

A ShopNest checkout request flows through middleware, hits a minimal API or controller, uses scoped services, and returns ProblemDetails on errors.

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
