I am creating a simple SqlHelper which will simplify the ADO.NET method usage. Can someone please review this class for any issue or missing something?public static class SqlHelper{    public static async Task<int> ExecuteNonQueryAsync(string connectionString, CommandType cmdType, string cmdText,        params SqlParameter[] commandParameters)    {        using (var connection = new SqlConnection(connectionString))        {            using (var command = new SqlCommand(cmdText, connection))            {                try                {                    command.CommandType = cmdType;                    command.Parameters.AddRange(commandParameters);                    connection.Open();                    return await command.ExecuteNonQueryAsync();                }                finally                {                    connection.Close();                }            }        }    }    public static async Task<SqlDataReader> ExecuteReaderAsync(string connectionString, CommandType cmdType,        string cmdText, params SqlParameter[] commandParameters)    {        using (var connection = new SqlConnection(connectionString))        {            using (var command = new SqlCommand(cmdText, connection))            {                try                {                    command.CommandType = cmdType;                    command.Parameters.AddRange(commandParameters);                    connection.Open();                    return await command.ExecuteReaderAsync();                }                finally                {                    connection.Close();                }            }        }    }    public static async Task<object> ExecuteScalarAsync(string connectionString, CommandType cmdType, string cmdText,        params SqlParameter[] commandParameters)    {        using (var connection = new SqlConnection(connectionString))        {            using (var command = new SqlCommand(cmdText, connection))            {                try                {                    command.CommandType = cmdType;                    command.Parameters.AddRange(commandParameters);                    connection.Open();                    return await command.ExecuteScalarAsync();                }                finally                {                    connection.Close();                }            }        }    }}
