High-intent search queries and answers about installing and using this skill.

FAQPage Schema
What is the best way to choose between EF Core and Dapper for a .NET data access layer?▼

Choosing between EF Core and Dapper requires evaluating performance, productivity, and AOT compatibility. EF Core prioritizes developer productivity, while Dapper offers better performance through lightweight object mapping.

When should I use raw ADO.NET instead of an ORM in my .NET application?▼

Use raw ADO.NET when you require maximum performance and full control over SQL execution. It provides the highest execution speed and AOT/trimming compatibility, but lacks the productivity features of ORMs like EF Core.

Can I combine EF Core and Dapper within a single .NET application?▼

Yes, you can combine EF Core and Dapper in a single .NET application. Implementing a hybrid data access strategy allows you to use EF Core for complex CRUD operations and Dapper for high-performance read-only queries.

Does EF Core support Native AOT and trimming in .NET data access scenarios?▼

EF Core has limitations with Native AOT and trimming due to its heavy reflection use. For .NET data access scenarios requiring strict AOT compatibility, lightweight micro-ORMs like Dapper or raw ADO.NET are recommended.

How do I migrate from Entity Framework Core to Dapper for better performance?▼

Migrating from EF Core to Dapper involves replacing ORM-managed queries with manual SQL statements. A hybrid approach is recommended, gradually migrating critical read paths to Dapper while leaving complex domain logic on EF Core to balance performance and productivity.
