How to pass data from controller to view

Short answer: Via ViewBag / ViewData / Model: return View(model); // Strongly typed ViewBag.Message = "Hello"; ViewData["Count"] = 5;

Example code

Via ViewBag / ViewData / Model: return View(model); // Strongly typed
ViewBag.Message = "Hello";
ViewData["Count"] = 5;

Real-world example (ShopNest)

A ShopNest checkout request flows through middleware, hits a minimal API or controller, uses scoped services, and returns ProblemDetails on errors.

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.
