ASP.NET Core Guide

Best Databases for ASP.NET Core (2026)

Compare the best database solutions for ASP.NET Core. We review SQL Server, PostgreSQL, and managed databases with Entity Framework Core integration.

Entity Framework Core is .NET's premier ORM with excellent provider support. We've evaluated databases that work well with EF Core's features and migration system.

Pourquoi C'est Important

EF Core provides powerful LINQ queries, change tracking, and migrations. The right database choice affects query performance, hosting options, and operational costs.

Considérations Clés

Entity Framework Core

EF Core is the standard ORM. Supports SQL Server, PostgreSQL, MySQL, SQLite, and more. LINQ queries, migrations, change tracking.

SQL Server vs PostgreSQL

SQL Server integrates best with Azure. PostgreSQL offers better value and works everywhere. Both have excellent EF Core providers.

Connection Resilience

Use EnableRetryOnFailure() for cloud databases. EF Core handles transient failures automatically.

Migrations

dotnet ef migrations add/update. Run in CI/CD or on startup. Works with all EF Core providers.

Dapper Alternative

Dapper for micro-ORM needs. Faster for simple queries. Use alongside EF Core for performance-critical paths.

Questions Fréquemment Posées

Should I use SQL Server or PostgreSQL with ASP.NET Core? ▼

SQL Server if you're on Azure and want first-party support. PostgreSQL for better value, cross-platform, and excellent Npgsql provider. Both work great with EF Core.

How do I run EF Core migrations in production? ▼

Use 'dotnet ef database update' in CI/CD, or call Database.Migrate() on startup. For production, prefer CI/CD migrations for better control.

When should I use Dapper instead of EF Core? ▼

Use Dapper for simple queries where you don't need change tracking. Use EF Core for complex domain models. They work well together in the same app.
