Why EF Core Performance Matters
Entity Framework Core is the most popular ORM in the .NET ecosystem. It makes data access simple, but that simplicity can hide inefficient queries, excessive database round trips, and memory issues.
Without proper optimization, EF Core can become the bottleneck in your application - especially under load.
This guide collects the most impactful performance techniques, organized from quick wins to advanced strategies.
