What are scalar properties, complex properties, and shadow properties?

Short answer: Scalar: Simple types like int, string, DateTime Complex: Nested objects mapped to multiple columns (Value objects) Shadow: Properties not defined in the .NET class but tracked by EF Core

Real-world example (ShopNest)

ShopNest’s order service uses EF Core to save an Order and its line items in one SaveChangesAsync() call inside a transaction.

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.
