adding initial rows into tables using Fluent migrator

Question

Im a classic programmer that is newbie at generics and this is an asp.net MVC5 sample application for learning purposes of integrating authorization (users/roles) using fluent migrator lib. I wantto add some sample datas into tables as they created (using migrator console tool).

getting compilation error: USERNAME does not exist in the current context
what should I add in to using section or any example of: Insert.IntoTable method ?

(thanks)

namespace SampleApp.Migrations
{
    [Migration(1)]
    public class AuthMigrations:Migration
    {
        public override void Up()
        {
            Create.Table("users").
                WithColumn("ID").AsInt32().Identity().PrimaryKey().
                WithColumn("USERNAME").AsString(128).
                WithColumn("EMAIL").AsCustom("VARCHAR(128)").
                WithColumn("PASSWORD_HASH").AsString(128);

            Create.Table("roles").
                WithColumn("ID").AsInt32().Identity().PrimaryKey().
                WithColumn("NAME").AsString(128);

            Create.Table("role_users").
                WithColumn("ID").AsInt32().Identity().PrimaryKey().
                WithColumn("USER_ID").AsInt32().ForeignKey("users", "ID").OnDelete(Rule.Cascade).
                WithColumn("ROLE_ID").AsInt32().ForeignKey("roles", "ID").OnDelete(Rule.Cascade);

            //Error:The name 'USERNAME' does not exist in the current context

            Insert.IntoTable("users").Row(new { USERNAME:"superadmin",EMAIL:"[email protected]",PASSWORD_HASH:"dfgkmdglkdmfg34532+"});
            Insert.IntoTable("users").Row(new { USERNAME:"admin",EMAIL:"[email protected]",PASSWORD_HASH:"dfgkmdglkdmfg34532+"});
        }

        public override void Down()
        {
            Delete.Table("role_users");
            Delete.Table("roles");
            Delete.Table("users");
        }

    }

and

 namespace SampleApp.Models
{
    public class User
    {
        public virtual int Id { get; set; }
        public virtual string Username { get; set; }
        public virtual string EMail { get; set; }
        public virtual string passwordhash { get; set; }
    }

    public class UserMap : ClassMapping<User>
    {
        public UserMap()
        {
            Table("Users");
            Id(x => x.Id, x => x.Generator(Generators.Identity));
            Property(x => x.Username, x => x.NotNullable(true));
            Property(x => x.EMail, x => x.NotNullable(true));
            Property(x=>x.passwordhash,x=>
            {
                x.Column("PASSWORD_HASH");
                x.NotNullable(true);
            });
        }
    }
}

In C#, you must use an equals sign ("=") in the object initializer instead of a colon (":").

Insert.IntoTable("users").Row(new { USERNAME = "superadmin",EMAIL = "[email protected]",PASSWORD_HASH = "dfgkmdglkdmfg34532+"});
Insert.IntoTable("users").Row(new { USERNAME = "admin",EMAIL = "[email protected]",PASSWORD_HASH = "dfgkmdglkdmfg34532+"});
