Entity Framework Core

Framework Core is an open-source -relational mapping (ORM) framework for ASP.NET applications. It provides a way to interact with using .NET , allowing developers to work with data in a more intuitive and object-oriented manner.

Example:

Let's say we have a database table “Customers” with columns such as “Id”, “Name”, and “”. With Entity Framework Core, we can define a corresponding C# class called “Customer” that represents this table:


public class Customer
{
    public int Id { get; set; }
    public  Name { get; set; }
    public string Email { get; set; }
}

Entity Framework Core allows us to perform various database on this “Customer” class, such as querying, inserting, updating, and deleting records.

Example:

Here's an example of querying the “Customers” table using Entity Framework Core:


using (var context = new DbContext())
{
    var customers = context.Customers.ToList();
     (var customer in customers)
    {
        Console.WriteLine($"Id: {customer.Id}, Name: {customer.Name}, Email: {customer.Email}");
    }
}

In this example, we create a new instance of the “DbContext” class, which represents the database context. We then use the “Customers” property of the context to query all the records from the “Customers” table and store them in a list. Finally, we over the list and print the details of each customer.

Entity Framework Core simplifies the process of working with databases in ASP.NET applications by providing a higher-level abstraction over the underlying database operations. It eliminates the need for writing raw SQL queries and allows developers to focus more on the application logic rather than the database interactions.
