How to handle exceptions using middleware

Short answer: (UseExceptionHandler, UseDeveloperExceptionPage) UseDeveloperExceptionPage() shows detailed errors (development only). UseExceptionHandler("/Error") handles errors in production with a custom page or handler. Example: if (env.IsDevelopment()) app.UseDeveloperExceptionPage(); else app.UseExceptionHandler("/Error"); Or inline: app.UseExceptionHandler(errorApp => { errorApp.Run(async context => {

Example code

context.Response.StatusCode = 500;
await context.Response.WriteAsync("An error occurred"); }); });

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.
