Map Table Name and Column Name in Entity Framework

Table name

[Table("blogs")]
public class Blog
{
    public int BlogId { get; set; }
    public string Url { get; set; }
}
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
    modelBuilder.Entity<Blog>()
        .ToTable("blogs");
}

Table schema

[Table("blogs", Schema = "blogging")]
public class Blog
{
    public int BlogId { get; set; }
    public string Url { get; set; }
}
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
    modelBuilder.Entity<Blog>()
        .ToTable("blogs", schema: "blogging");
}

Rather than specifying the schema for each table, you can also define the default schema at the model level with the fluent API:

protected override void OnModelCreating(ModelBuilder modelBuilder)
{
    modelBuilder.HasDefaultSchema("blogging");
}

Column name

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

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