To read a table in ASP.NET Core using the database-first approach, follow these steps:

  1. Create a DbContext class that inherits from DbContext.
  2. In your DbContext class, add a property for each table that you want to read. The property should be of type DbSet.
  3. Create a controller that exposes display the data to user. Your controller should have a method to retrieve data from the DbContext class.
  4. In the view, bind the controller data to the UI.

Here is an example of how to read a table in ASP.NET Core with database first approach:

C#

public class MyContext : DbContext
{
    public DbSet<Customer> Customers { get; set; }
}

public class CustomerController : Controller
{
    private readonly MyContext _context;

    public CustomerController(MyContext context)
    {
        _context = context;
    }

    public ActionResult Index()
    {
        var customers = _context.Customers.ToList();
        return View(customers);
    }
}

In this example, we first create a DbContext class named MyContext. The class MyContext has a property called Customers of type DbSet. This property represents the Customers table in the database.

Then we create a controller named CustomerController. The class CustomerController has a method called Index(). The Index() method gets the data from the Customers table in the database and returns it to the view.

The view then binds the data from the controller to the UI.
