ASP.NET Core Anleitung 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.
Warum es wichtig ist
EF Core provides powerful LINQ queries, change tracking, and migrations. The right database choice affects query performance, hosting options, and operational costs.
Wichtige Überlegungen
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.
