I'm doing a project where I have to use EF, but trying to add new data to the table seems to fail every time. I have no knowledge to why/how I can fix it.

The code executing is:

private static void AddCustomer()
{
        WriteAdminMenu("Add new customer");
        Console.Write("First name: ");
        ...
        WriteAdminMenu("Adding customer...");

        using (var db = new EshopContext())
        {
            db.Addresses.Add(new Address(customerStreet, customerZip, customerCity, customerCountry));
        }
    }

And I get the following error:

System.InvalidOperationException: No suitable constructor was found for entity type 'Address'. The following constructors had parameters that could not be bound to properties of the entity type: cannot bind 'zip' in 'Address(string street, string zip, string city, string country)'

Context file:

public class EshopContext : DbContext
{
    public DbSet<Customer>? Customer { get; set; }
    public DbSet<Address>? Addresses { get; set; }
    public DbSet<Order>? Orders { get; set; }
    public DbSet<Product>? Products { get; set; }
    public DbSet<Tag>? Tags { get; set; }

    protected override void OnConfiguring(DbContextOptionsBuilder options)
       => options.UseSqlServer("Data Source=TotallyMyIp;Initial Catalog=MyDatabaseName;Persist Security Info=True;User ID=TotalyMyUserName;Password=totallySecretPassword");
}

And my address model:

public class Address
{
    public int Id { get; set; }
    public string Street { get; set; }
    public string Zipcode { get; set; }
    public string City { get; set; }
    public string Country { get; set; }

    public Address(string street, string zip, string city, string country)
    {
        Street = street;
        Zipcode = zip;
        City = city;
        Country = country;
    }
}

CodePudding user response：

The framework has no way to know that zip is the same as Zipcode.

Keep your names consistent:

public Address(string street, string zipcode, string city, string country)
