type Stocks = CsvProvider<"msft.csv">
let stockData = Stocks.Load("msft.csv")

// Show AST of Rows getter
<@ stockData.Rows @>.Raw

// Normal usage of Rows 
stockData.Rows
|> Seq.iter (fun row -> printfn "Date: %A Open: %A" row.Date row.Open)

// Iterate through Rows again, but this time show the AST provided
// that gets the strongly-typed tuple value for the 'Low' column
stockData.Rows
|> Seq.iter (fun row -> printfn "%A" <@ row.Low @>)
