How to Specify Entity Framework Core Table Mapping?

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");
         });
     }
 }

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)
                 .HasColumnName("MyPasswordHashColumn")
         );
     }
 }
