EF Core Tools & Extensions
These tools and extensions provide additional functionality for Entity Framework Core.
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
EF Core Power Tools
EF Core Power Tools is a Visual Studio extension that exposes various EF Core design-time tasks in a simple user interface. It includes reverse engineering of DbContext and entity classes from existing databases and SQL Server DACPACs, management of database migrations, and model visualizations. For EF Core: 6-8.

Extends your DbContext with high-performance bulk operations: BulkSaveChanges, BulkInsert, BulkUpdate, BulkDelete, BulkMerge, and more. For EF Core: 2-8.
Expressionify
Add support for calling extension methods in LINQ lambdas. For EF Core: 3-6.

- 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".
