EF Core Tools & Extensions

These tools and extensions provide additional functionality for Entity Framework Core 3 and later.

Important

Extensions are built by a variety of sources and aren't maintained as part of the Entity Framework Core project. When considering a third party extension, be sure to evaluate its quality, licensing, compatibility, support, etc. to ensure it meets your requirements. In particular, an extension built for an older version of EF Core may need updating before it will work with the latest versions.

Tools

LLBLGen Pro

LLBLGen Pro is an entity modeling solution with support for Entity Framework and Entity Framework Core. It lets you easily define your entity model and map it to your database, using database first or model first, so you can get started writing queries right away. For EF Core: 2, 3, 5, 6.

nHydrate ORM for Entity Framework

An O/RM that creates strongly-typed, extendable classes for Entity Framework. The generated code is Entity Framework Core. There is no difference. This is not a replacement for EF or a custom O/RM. It is a visual, modeling layer that allows a team to manage complex database schemas. It works well with SCM software like Git, allowing multi-user access to your model with minimal conflicts. The installer tracks model changes and creates upgrade scripts. For EF Core: 3.

  • Full C# support for query creation: multiple statements inside lambda, variables, functions, etc.
  • No semantic gap with SQL. EntityLinq declares SQL statements (like SELECT, FROM, WHERE) as first class C# methods, combining familiar syntax with intellisense, type safety and refactoring.

As a result SQL becomes just "another" class library exposing its API locally, literally "Language Integrated SQL".
