How do you reverse engineer a database in EF Core (DB First) into entity classes & DbContext?

Short answer: Use the CLI or Package Manager Console: dotnet ef dbcontext scaffold "YourConnectionString" Microsoft.EntityFrameworkCore.SqlServer -o Models OR Scaffold-DbContext "YourConnectionString" Microsoft.EntityFrameworkCore.SqlServer -OutputDir Models ✅ It generates: Entity classes DbContext class Mappings based on database schema

Real-world example (ShopNest)

ShopNest registers AppDbContext as scoped. One HTTP request = one context. Never inject it as a singleton.

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.
