EFCore.BulkExtensions is a library that extends Entity Framework Core with high-performance bulk operations for database CRUD tasks.
The library addresses the performance limitations of standard Entity Framework Core operations when working with large datasets. It provides bulk Insert, Update, Delete, Read, Upsert, and Sync operations that use direct database protocols rather than the standard ORM mapping layer, delivering significantly faster execution. The tool also offers batch operations for Update and Delete with chunk-oriented processing, and includes a Truncate operation. It supports five major SQL databases: SQL Server, PostgreSQL, MySQL, Oracle, and SQLite, with compatibility across recent versions of Entity Framework Core.
Developers should adopt this tool when working with applications that require moving large volumes of data efficiently. It suits projects where standard Entity Framework Core operations create performance bottlenecks, particularly those handling big-data scenarios or fintech workloads with substantial datasets. The library is lightweight and maintains compatibility with the Entity Framework Core ecosystem, making it a drop-in enhancement rather than a replacement. The tool has been recognized by Microsoft as a recommended EF Core extension.
The project maintains a substantial user base, with most issues raised by adopters reporting real-world use rather than by the core team. Maintainers typically respond to new issues and pull requests within a few days. Work in the issue tracker centers on questions, enhancements, and bug reports.
