При попытке сменить пароль выдает ошибку

The property 'password' is part of the object's key information and cannot be modified.

[SRC=csharp]
private void button3_Click(object sender, EventArgs e)
{
string _user = txtUsername.Text;

tbl_user _tbl = _dbObj.tbl_user.First(i => i.username == txtUsername.Text);
_tbl.password = txtPassword.Text;
_dbObj.SaveChanges();
MessageBox.Show("Update Successfully....");
}

[SRC="csharp"]account.Password = "password";

using (var context = new PlayerContext())
{
context.Accounts.AddOrUpdate(account);
context.SaveChanges();
}

Так же подозреваю, что не установлен ключ (атрибут Key для Id). Изучай.

Каким образом это относится к PointBlank/Piercing Blow?
