Entity Framework

EF Core is a modern object-database mapper for .NET.

In .NET applications, ADO.NET is an old and powerful method for accessing databases and requires a lot of coding. Simply put, all of the work is done manually. Microsoft has therefore introduced Entity Framework to automate the database technique.

EF Core

Entity Framework (EF) Core is a open source and cross-platform object-relational mapper (O/RM) for .NET, which:

• Enables developers to work with a database using .NET objects.

• Eliminates the need for most of the data-access code that typically needs to be written.

• It supports LINQ queries, change tracking, updates, and schema migrations.

• EF Core works with many databases, including SQL Database (on-premises and Azure), SQLite, MySQL, PostgreSQL, and Azure Cosmos DB.
