SOLID Design Principles Tutorial · ASP.NET Core

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

How to structure your answer (60–90 seconds)

Define ASP.NET Core in plain language for SOLID Design Principles.
Context — where it appears in a typical .NET project.
Example — one sentence from work, internship, or a practice app.
Trade-off — what you gain vs what you sacrifice.

Real-world example

A ShopNest checkout API registers authentication middleware before authorization, uses scoped DbContext, and returns ProblemDetails for errors.

Step-by-step talking points

Draw the request pipeline
Explain middleware order (auth before endpoints)
Mention DI lifetimes (scoped per request)
Give one production tuning tip (compression, caching)

Mistakes to avoid

Blocking async calls in controllers
Singleton service holding scoped DbContext
Missing HTTPS redirection in production

Practice aloud. Pair this with the full SOLID Design Principles interview library and timed practice exams on Toolliyo.

Step-by-step talking points

Define in one sentence
Explain where it fits in the stack
Give a concrete example
Name one failure mode and prevention

Mistakes to avoid

Rambling over 3 minutes
No project context
Buzzwords without implementation detail
