How to Specify Entity Framework Core Table Mapping?

Question

I\'ve made a simple Entity Framework ASP Core Application which works but I do not know why:

I\'ve made a context like this:

public class AstootCont

1. To specify the name of the database table, you can use an attribute or the fluent API:

   Using Attributes:

   [Table("MyAccountsTable")]
   public class Account
   {
        public string PasswordHash { get; set; }
   }
   

   Using Fluent API:

   public class YourContext : DbContext
   {
       protected override void OnModelCreating(ModelBuilder builder)
       {
           builder.Entity<Language>(entity => {
               entity.ToTable("MyAccountsTable");
           });
       }
   }
   

2. To name your columns manually, it's very similar and you can use an attribute or the fluent API:

   Using Attributes:

   public class Account
   {
       [Column("MyPasswordHashColumn")]
       public string PasswordHash { get; set; }
   
   }
   

   Using Fluent API:

   public class YourContext : DbContext
   {
       protected override void OnModelCreating(ModelBuilder builder)
       {
           builder.Entity<Language>(x => x
               .ToTable("MyAccountsTable")
               .Property(entity => entity.PasswordHash)
                   .HasField("MyPasswordHashColumn")
           );
       }
   }
