adding initial rows into tables using Fluent migrator - asp.net-mvc-5

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:"superadmin#mvcapp.com",PASSWORD_HASH:"dfgkmdglkdmfg34532+"});
Insert.IntoTable("users").Row(new { USERNAME:"admin",EMAIL:"admin#mvcapp.com",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 = "superadmin#mvcapp.com",PASSWORD_HASH = "dfgkmdglkdmfg34532+"});
Insert.IntoTable("users").Row(new { USERNAME = "admin",EMAIL = "admin#mvcapp.com",PASSWORD_HASH = "dfgkmdglkdmfg34532+"});
