SQLite cause XamlParseException when executing ExecuteNonQuery()

Today I tried to use SQLite database with my small WPF application, but I keep getting XamlParseException was unhandled. By taking out lines of code, I managed to notice that cmd.ExecuteNonQuery();causes the exception. In the rest, the SQLite connection seems working and also creating the database file.

public MainWindow()
{
    InitializeComponent();
    SQLiteConnection conn = new SQLiteConnection(@"Data Source=C:\Users\Vitas\Desktop\TimeCounter.sqlite");
    conn.Open();
    string commandText = "CREATE TABLE  [EmpInfo]";
    SQLiteCommand cmd = new SQLiteCommand(commandText, conn);
    cmd.ExecuteNonQuery();
    conn.Close();
}
