Top 10 EntityFramework Libraries in 2017

EntityFramework is an open source object-relational mapping (ORM) framework for ADO.NET. Initially it was a part of .NET Framework, but eventually, it is separated from .NET framework since Entity framework 6. It continues to remain the favorite ORM for .NET developers and is a part of the huge portion of startups and organization.

Entity framework is valuable in three situations;

  • Database First: You have already a database, or you need to plan your database in front of different parts of the application and after that create your domain classes from the database.
  • Code First: You need to concentrate on your domain classes and after that create the database from your domain classes.
  • Model First: You need to design your database schema and afterward create the domain classes and database.

In Entity Framework, programmers execute queries using LINQ, to retrieve and manipulate data. It also provides services like change tracking, identity resolution, lazy loading, and query translation so that programmers can concentrate on their application-particular business logic instead of data access fundamentals.

There are a lot of libraries available which can enhance, extend, and improve the functionality of Entity Framework, e.g., EntityFramework is reputed to be very slow when saving multiple entities. The performance issue is mainly due to the DetectChanges method and the number of database round-trip. Z.EntityFramework.Extensions is a library that dramatically improves the performance because it only requires a few database round-trip.

In this article, we will discuss the top 10 libraries, or you can say the most useful libraries which are used in 2017.
