Kas on Entity Framework ja milleks seda kasutatakse arenduses?

Entity Framework (EF) is an object-relational mapper (ORM) for the .NET platform, which allows developers to work with a database using .NET objects instead of writing SQL queries directly.

Key features of EF:

• Automatic conversion of data from database tables to objects and vice versa.
• Management of database migrations.
• Support for LINQ queries for convenient and type-safe data access.

Example of using EF to retrieve a list of users:

using(var context = new AppDbContext()) {
    var users = context.Users.Where(u => u.IsActive).ToList();
}

Thus, EF simplifies working with data, increases development productivity, and reduces the likelihood of errors when working with the database.
