What does app.MapGet do in minimal APIs?
PICTURE THIS: A REST CALL
ClientGET /users/1
ServerFind row
JSON back200 OK
Simple meaning
It maps an HTTP GET endpoint to a handler delegate.
WHY — ASP.NET instead of guessing?
Why interviewers care about ASP.NET:
ASP.NET questions separate people
who only read docs from people who shipped.
Keep it short, concrete,
and tied to .NET 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.
STEPS — What happens step by step?
Before you speak the answer, walk the interviewer through these steps:
- 1It maps an HTTP
GET endpoint to a handler delegate.
- 2Why it exists
Great for small APIs.
- 3Larger apps still use
controllers when organization helps.
- 4Give an example
One tiny concrete case you can say aloud.
- 5Common mistake
What juniors usually get wrong.
- 6Close
When you pick this over the alternative.
