How do you write a custom middleware?

Short answer: wait _next(context); // Post-processing logic } } Register it: pp.UseMiddleware<MyCustomMiddleware>(); wait _next(context); // Post-processing logic } } Register it: pp.UseMiddleware<MyCustomMiddleware>(); wait _next(context); // Post-processing logic } } Register it: pp.UseMiddleware<MyCustomMiddleware>(); wait _next(context); // Post-processing logic } }… Register it: pp.UseMiddleware<MyCustomMiddleware>();

Real-world example (ShopNest)

ShopNest pipeline order matters: exception handling → HTTPS → auth → authorization → endpoints. Auth must run before protected APIs.

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.
