    Entity Framework Plus

    Entity Framework Plus

    Entity framework plus extends your DbContext with must-haves features

    Entity Framework Plus extends your DbContext with must-haves features, include filter, auditing, caching, query future, batch delete, batch update, and more. Deleting using Entity Framework Core can be very slow if you need to delete hundreds or thousands of entities. Entities are first loaded in the context before being deleted which is very bad for the performance and then, they are deleted one by one which makes the delete operation even worse. EF+ Batch Delete is the most efficient way to delete records. You drastically improve your application performance by removing the need to retrieve and load entities in your context and by performing a single database roundtrip instead of one for every record. ...
