F# and ADO.NET - idiomatic F#

Question

I\'m just starting to learn F#. I wrote this F#/ADO.NET code last night. In what ways would you improve the syntax - make it feel like idiomatic F#?

    let cn =

Well, there's not much you can change in the first bit but whenever you're processing collections of data like in the last few rows, you can use the built-in Seq, List, Array functions.

for i in 0 .. (rowCount - 1) do
  let row:DataRow = rowCol.[i]
  printfn "%A" row.["LastName"]

=

rowCol |> Seq.cast 
       |> Seq.iter (fun row -> printfn "%A" row.["LastName"])
