Learning F# 3.0 : LINQ in F# (sample for FizzBuzz)

To use LINQ in F#, There is no need for creating mapper function. And there is also no need for using accumulator in reducer function. The below is the sample for FizzBuzz.

module FizzBuzzLinq =
    open System.Data
    open System.Data.Linq

    let fizzBuzz (fromNum:int) (toNum:int) =
        let fizzBuzzReducer (number:int) =
            match (number % 3, number % 5) with
            | (0, 0) -> "FizzBuzz"
            | (0, _) -> "Fizz"
            | (_, 0) -> "Buzz"
            | (_, _) -> number.ToString()
        let numberList = [ fromNum..toNum ]
        query { for number in numberList do
                select (fizzBuzzReducer number) }

(FizzBuzzLinq.fizzBuzz 1 40) |> Seq.iter (fun elem -> System.Console.WriteLine(elem))
