	string sql = "SELECT '1' AS A WHERE @Fizz = 1 FOR XML RAW";
     var dict = new Dictionary<string, object> {{"@Fizz", 1}};
	
	using (var conn = new SqlConnection(FiddleHelper.GetConnectionStringSqlServer()))
    {
        conn.Open();
        
		//C# Extension Method: SqlConnection - ExecuteXmlReader
        using (XmlReader reader = conn.ExecuteXmlReader(sql, dict.ToSqlParameters()))
        {
            reader.Read();

            object result = reader[0];
        	Console.WriteLine(result);
