Make navigation properties virtual:?

Short answer: public virtual Category Category { get; set; } public virtual Category Category { get; set; } public virtual Category Category { get; set; } public virtual Category Category { get; set; } public virtual Category Category { get; set; } public virtual Category Category { get; set; } public virtual Category Category { get; set; } public virtual Category Category { get; set; }

Example code

public virtual Category Category { get; set; } public virtual Category Category { get; set; } public virtual Category Category { get; set; } public virtual Category Category { get; set; } public virtual Category Category { get; set; } public virtual Category Category { get; set; } public virtual Category Category { get; set; } public virtual Category Category { get; set; }

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.
