Database First Approach with EF Core (Scaffold) — ShopNest
Article 21 of 75 · Module 2: Entity Framework Core · ShopNest Legacy HR System Migration
Target keyword: ef core database first · Read time: ~28 min · .NET: 8 / 9 · Project: ShopNest Legacy HR System Migration

Introduction

Not every ShopNest integration starts greenfield. Database First scaffolds entities from an existing HR database — common when migrating legacy systems at TCS/Wipro-style maintenance projects.

After this article you will

  • Run dotnet ef dbcontext scaffold with options
  • Extend scaffolded models with partial classes
  • Refresh after DBA schema changes
  • Map stored procedures and database views
  • Mix Code First for new modules on same DB

Prerequisites

Concept deep-dive

dotnet ef dbcontext scaffold   "Server=.;Database=LegacyHR;Trusted_Connection=True;"   Microsoft.EntityFrameworkCore.SqlServer   --output-dir Models/Scaffolded   --context-dir Data   --context LegacyHrContext   --force   --no-onconfiguring

Partial classes: never edit scaffolded files — add Employee.Partial.cs with computed properties.

// Keyless entity for DB view
modelBuilder.Entity<EmployeeSummaryView>(b =>
{
    b.HasNoKey();
    b.ToView("vw_EmployeeSummary");
});

// Stored procedure
var results = await _db.EmployeeBonuses
    .FromSqlRaw("EXEC hr.GetBonuses @Year = {0}", 2025)
    .ToListAsync();

Hands-on — ShopNest Legacy HR System Migration

  1. Scaffold from sample LegacyHR database (or LocalDB script).
  2. Partial class adds FullName computed property.
  3. Map reporting view as keyless entity for read-only dashboard.
  4. Document re-scaffold workflow for team when DBA adds columns.

Common errors & best practices

  • Editing generated files — overwritten on re-scaffold; use partials.
  • Scaffolding entire server with 200 tables — scaffold specific tables with --table flags.

Interview questions

Q: When Database First?
A: Legacy DB, no ownership of schema, brownfield migration.

Q: Code First vs Database First?
A: Code First — dev owns schema. Database First — DBA owns schema, app adapts.

Summary

  • Scaffold-DbContext reverse-engineers existing SQL Server
  • Partial classes extend without losing regeneration
  • Views and sprocs map to keyless entities / FromSqlRaw
  • Common in legacy HR migration scenarios

FAQ

Can I mix Code First migrations with scaffolded context?

Use separate contexts or carefully merge — one DbContext per bounded context is cleaner.

How update after schema change?

Re-scaffold with --force or add migration if you own schema via Code First.
