Real-world example (ShopNest)

In a ShopNest .NET service, explain the idea in one sentence, show where it sits in the request/data flow, then give one production trade-off.

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.

Short answer: ASP.NET Core is cross-platform, uses Kestrel, middleware pipeline, and built-in DI. Requests flow: routing → middleware → endpoints → filters → action.
