Add data to the SQLite database using Textbox

I have a problem, need to get data (string) from textboxes and add to the new string of the table, but my code causes an exception:

SQL logic error or missing database

no such table: NoteTestTable2

Code:

public partial class MainWindow : Window
{
    string dbConnectionString = @"Data Source=NoteTest.sqlite;Version=3;";//Создаем соединение с нашей базой данных "NoteTest"

    public MainWindow()
    {
        InitializeComponent();
    }

    private void NameTextBox_TextChanged(object sender, TextChangedEventArgs e)
    {
    }

    private void SaveData_Click(object sender, RoutedEventArgs e)
    {
        SQLiteConnection sqliteCon = new SQLiteConnection(dbConnectionString);

        try
        {
            sqliteCon.Open();//Открываем соединение с бд
            string Query = "INSERT INTO NoteTestTable2 (Name,LastName) VALUES('" + this.NameTextBox.Text + "' , '" + this.LastNameTextBox.Text + "' )";//Создаем наш запрос SQL и помещаем его в переменную Query

            SQLiteCommand CreateCommand = new SQLiteCommand(Query, sqliteCon);

            CreateCommand.ExecuteNonQuery();

            SQLiteDataReader dr = CreateCommand.ExecuteReader();
            MessageBox.Show("Запись внесена!");
            sqliteCon.Close();
        }
        catch(Exception ex)
        {
            MessageBox.Show(ex.Message);
        }
    }
}
