How to handle exceptions using middleware (UseExceptionHandler, UseDeveloperExceptionPage) ● UseDeveloperExceptionPage() shows detailed errors (development only). ● UseExceptionHandler("/Error") handles errors in production with

Short answer: custom page or handler. if (env.IsDevelopment()) pp.UseDeveloperExceptionPage(); else pp.UseExceptionHandler("/Error"); Or inline: pp.UseExceptionHandler(errorApp => { errorApp.Run(async context => { context.Response.StatusCode = 500; wait context.Response.WriteAsync("An error occurred"); }); }); custom page or handler.…

if… (env.IsDevelopment()) pp.UseDeveloperExceptionPage(); else pp.UseExceptionHandler("/Error"); Or inline: pp.UseExceptionHandler(errorApp => { errorApp.Run(async context => { context.Response.StatusCode = 500; wait context.Response.WriteAsync("An error occurred"); }); }); custom page or handler.

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.
