How do you structure Clean Architecture in a .NET solution?
PICTURE THIS: A REST CALL
ClientGET /users/1
ServerFind row
JSON back200 OK
Simple meaning
Domain has no infra references
WHY — Architecture instead of guessing?
Why interviewers care about Architecture:
This is a process
question about Architecture.
Panels listen for order,
trade-offs, and what you would actually do on a .NET project - not buzzwords.
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:
- 1Define it
Domain has no infra references
- 2Why it exists
application defines ports
- 3How it works
infrastructure implements EF and HTTP.
- 4Give an example
Web layer only orchestrates.
- 5I keep vertical slices
when the team finds too many projects heavy.
- 6Close
When you pick this over the alternative.
EXAMPLE — See it in action
Here's a short line you can speak, broken into clear beats:
Say this line
“Web layer only orchestrates.”

Note: Adapt this scaffold to your own project — keep it under 60–90 seconds.
Key takeaway
Domain has no infra references application defines ports
