What is HttpNotFoundResult?
PICTURE THIS: A REST CALL
ClientGET /users/1
ServerFind row
JSON back200 OK
Simple meaning
Legacy style 404 result.
WHY — MVC instead of guessing?
Why interviewers care about MVC:
MVC questions separate people
who only read docs from people who shipped.
Keep it short, concrete,
and tied to .NET MVC work.
Stay structured
Name the idea, why it exists, then one short example.
Close cleanly
End with when you use it and one common pitfall.

- 5Common mistake

When you pick this over the alternative.
