DeveloperExceptionPage (for development) Example:?

Short answer: pp.UseExceptionHandler("/Home/Error"); or public class GlobalExceptionFilter : IExceptionFilter { public void OnException(ExceptionContext context) { context.Result = new ViewResult { ViewName = "Error" }; } } 🧩 19.

Explain a bit more

pp.UseExceptionHandler("/Home/Error"); or public class GlobalExceptionFilter : IExceptionFilter { public void OnException(ExceptionContext context) { context.Result = new ViewResult { ViewName = "Error" }; } } 🧩 19. {

Example code

public void OnException(ExceptionContext context)
{
context.Result = new ViewResult { ViewName = "Error" };
}
} 🧩 19. How to return partial views? Partial views are used to render reusable page sections (like headers, sidebars). Example: public IActionResult ProductList()
{
var products = _service.GetAll();
return PartialView("_ProductListPartial", products);
} In Razor: @Html.Partial("_ProductListPartial", Model.Products) 🧾 20. Explain Razor Pages vs MVC. Feature Razor Pages MVC Structure Page-based (.cshtml + .cshtml.cs) Controller + View Best For Simple or CRUD pages Complex or large web apps URL /Products/Edit → /Pages/Products/Edit.cshtml /Products/Edit → ProductController.Edit() Code Location In the same file (PageModel) Separate Controller class Example: Razor Pages are like simplified MVC without controllers — great for admin dashboards or forms. Dependency Injection (DI)

Real-world example (ShopNest)

ShopNest admin screens use MVC: controller loads data, Razor view renders HTML, Tag Helpers build forms safely.

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.
